Opis:
Arbuscular mycorrhizal fungi (AMF) and dark septate endophyte (DSE) associations were studied in 36 medicinal plant species from 33 genera and 17 families, collected from the Botanical Garden of the Jagiellonian University in Kraków. Arbuscular mycorrhiza (AM) was found in 34 species (94%); 26 were of the Arum-type, 4 – Paris and 4 taxa revealed intermediate morphology. The abundance of AMF hyphae in roots varied with particular species, ranging from 2.5% (Helianthus tuberosus) to 77.9% (Convallaria majalis). The mycelium of DSE was observed in 13 plant species (36%), however, the percentage of root colonization by these fungi was low. Spores of 7 AMF species (Glomeromycota) were isolated from trap cultures established from rhizosphere soils of the investigated plants: Archaeospora trappei (Archaeosporaceae), Glomus aureum, Glomus caledonium, Glomus claroideum, Glomus constrictum, Glomus mosseae, Glomus versiforme (Glomeraceae). Our results are the first detailed report of root endophyte associations of the plant species under study. Moreover, the mycorrhizal status of 14 plant species is reported for the first time.

Opis:
Abscisic acid (ABA) is an ubiquitous plant hormone and one of the foremost signalling molecules, controlling plants' growth and development, as well as their response to environmental stresses. To date, the function of ABA has been extensively investigated as an abiotic stress molecule which regulates the plants' water status. However, in the context of symbiotic associations, ABA is less recognized. In contrast to well-described auxin/cytokinin and gibberellin/strigolactone involvement in symbioses, ABA has long been underestimated. Interestingly, ABA emerges as an important player in arbuscular mycorrhiza and legume-rhizobium symbiosis. The plant's use of stress hormones like ABA in regulation of those interactions directly links the efficiency of these processes to the environmental status of the plant, notably during drought stress. Here we provide an overview of ABA interplay in beneficial associations of plants with microorganisms and propose ABA as a potential factor determining whether the investment in establishing the interaction is higher than the profit coming from it.

Opis:
Zinc (Zn) is an important element for the proper plant growth and development. However, Zn is also a metal commonly used in the industry, which may cause its excessive accumulation in soil. High soil Zn content leads to its increased uptake by plants growing near industrialized areas. Arbuscular mycorrhizal fungi (AMF) live in symbiosis with the majority of plant species. These fungi have the ability to reduce Zn uptake by plants, when this element is present in an increased concentration in the plant root zone. An experiment was carried out to determine the effect of AMF on Zn uptake by lettuce plants grown in rockwool at increasing levels of Zn in the nutrient solution. This effect was investigated at two P levels in the nutrient solution, i.e. 40 mg P (optimal for lettuce) and 10 mg P dm-3. Mycorrhizal parameters, yield, content of dry matter, ascorbic acid, glucose, fructose and sucrose as well as the plant’s nutritional status in P, Cu, Mn, Mo, Fe and Zn were determined in the study. The effectiveness of mycorrhization of lettuce grown in rockwool was proven in the study. AMF reduced the Zn content in lettuce grown under excessive Zn concentrations in the root zone. Moreover, this decrease was greater in plants receiving the nutrient solution with a lower concentration of P. Additionally, mycorrhiza decreased the content of Cu, Fe, Mn and Mo in lettuce, despite an optimal (not increased) concentration of these micronutrients in the nutrient solution supplied to plants. Arbuscular mycorrhiza did not affect the plant yield, content of ascorbic acid, glucose, fructose, sucrose or the content of P in lettuce leaves.

Opis:
The effect of arbuscular mycorrhizal fungi (Glomus geosporum) inoculation on Telfairia occidentalis grown in saline soil was investigated in a pot experiment. The experiment was laid out in a completely randomized design, with treatments replicated thrice. Standard recommended methods were used to determine photosynthetic pigments, minerals contents, biomass yield, AMF colonization and dependency. Our results show that saline soil treatment significantly (p=0.05) reduced total photosynthetic pigments contents - from 39.73 to 21.30 mg/kg, percentage AMF root colonization - from 53.97 to 22.41%, mineral contents; N - from 5.84 to 3.13%; P - 424.11 to 212.31 mg/kg; K - 3215.00 to 1220.00 mg/kg; Mg - 326.00 to 107.04 mg/kg; and Ca - 1640.00 to 813.00 mg/kg. Biomass yield of T. occidentalis was also significantly (p=0.05) reduced. In contrast, mycorrhizal dependency was significantly (p=0.05) increased in saline soil plants - from 15.13% to 100.00%. Herein, inoculation with G. geosporum significantly (p=0.05) increased total photosynthetic pigments - from 39.73 to 45.53 mg/kg; N - from 5.84 to 6.07%; P - 424.11 to 463.00 mg/kg; K - 3215.00 to 3470.12 mg/kg; Mg - 326.00 to 345.00 mg/kg and Ca -1640 to 1658.12 mg/kg; leaf dry weight - from 0.13 to 0.17g; vine dry weight - 5.21 to 5.81g; roots dry weight - 0.57 to 1.03 and total dry weight - 5.91 to 7.01g. Biomass yield was also significantly increased. R. irregularis colonization (from 22.41 to 53.97%) and mycorrhizal dependency in C. maxima was evident in both saline and non-saline soil treatments. The results of this work have shown that G. geosporum can enhance the ability of T. occidentalis to resist salt stress (possibly through several morphological/physiological changes and through improved vigour) via the extensive network of the mycorrhizal roots (which increases nutrient and water uptake). Inoculation with appropriate AMF can, therefore, be used to increase the productivity of T. occidentalis in saline soils.

Opis:
In December 1997 and June-July 2000, 49 and 113 rhizosphere soil and root mixtures were collected, respectively, to determine the occurrence of arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota in different sites of Israel. Except for five samples taken from under cultivated plants, all the others came from under Ammophila arenaria and Oenothera drummondii colonizing sand dunes adjacent to the Mediterranean Sea. After a continuous cultivation of the mixtures in pot trap cultures with Plantago lanceolata as the plant host up to 2006 and their examination at least twice a year, spores of AMF were found in 41 and 103 cultures with the 1997 and 2000 soil and root mixtures, respectively. The spores represented 30 species and 8 undescribed morphotypes in 7 genera of the Glomeromycota. The AMF most frequently found in Israeli soils were Glomus aurantium and G. constrictum, followed by G. coronatum, G. gibbosum, an undescribed Glomus 178, and Scutellospora dipurpurescens. Up to 2001, 21 species of AMF were known to occur in Israel, and this paper increases this number to 33, of which 11 are new fungi for this country. Moreover, four species, G. aurantium, G. drummondii, G. walkeri and G. xanthium, were recently described as new for science based on spores isolated from Israeli soils. Additionally, the general distribution in the world of the formally described species found in Israel was presented.

Opis:
This is the first report of an ecological investigation on endomycorrhizal symbiosis in Curcuma aeruginosa, a medicinally and nutritionally important herb. Samples were collected from the field, where the plant grows under natural condition. AM fungal and soil fertility parameters were analysed as per standard methods. Altogether 16 different AM fungal species from seven different soil series are discovered. AM fungal species composition varied among soil series. Species richness of AM fungi was positively correlated with organic carbon content of soil. Shannon's diversity index and Simpson's index in the study area were measured. High intensity of AM fungal colonization in the roots of naturally growing C. aeruginosa suggests the need of proper management of the association in its cultivation practices also. Data obtained from the present investigation may help for the development of native AM fungi based biofertilizer based for a sustainable soil fertility management and cultivation of the crop.

Opis:
The influence of mycorrhizal fungi (Rhizophagus irregularis) on salt tolerance of Cucurbita maxima grown in saline soil was investigated in a pot experiment. The experiment was laid out in a completely randomized design, with treatments replicated thrice. Accordingly, soil salinity significantly (p=0.05) reduced total photosynthetic pigments from 58.06 to 38.06 mg/kg. Mineral contents, biomass yield, AMF colonization were also significantly (p=0.05) reduced. In contrast, mycorrhizal dependency was significantly (p=0.05) increased in saline soil plants (from 26.91% to 66.45%). Furthermore, inoculation with R. irregularis significantly (p=0.05) increased total photosynthetic pigments from 58.06 to 62.06 mg/kg; N from 4.88 to 5.47%; P 860.40 to 896.22 mg/kg; K 4430.00 to 4630.00 mg/kg; Mg 558.99 to 592.10 mg/kg and Ca 2810.00 to 3151.00 mg/kg; biomass yield; leaf dry weight from 0.06 to 0.14g; vine dry weight 3.68 to 5.09g; roots dry weight 0.32 to 0.74 and total dry weight 4.06 to 5.97g, R. irregularis colonization (from 33.77 to 58.44%) and mycorrhizal dependency in C. maxima was evident in both saline and non-saline soil treatments. The results of this work shows that R. irregularis can enhance the ability of C. maxima to resist salt stress - possibly through some morphological/ physiological changes, as well as improved vigour, probably via the extensive network of the mycorrhizal roots. This last is considered to be one of several mechanisms that magnify the salt tolerance of host plants through increased nutrient acquisition (N, P, K, Mg and Ca) and water uptake. Inoculation with appropriate AMF can, therefore, be used to increase the productivity of C. maxima in saline soils.

Opis:
Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.

Opis:
The distribution of trees depends on the climate, but mycorrhizal symbiosis shapes their distribution along the climatic gradient and the ability of trees to resistant the effects of climate change. Ectomycorrhiza is adapted to the cold climate so ectomycorrhizal trees predominate in boreal, mountain and temperate forests. Arbuscular mycorrhizal tree species are few in temperate forests but common in the dry and warm climate in tropical and subtropical zones. Some trees can enter dual mycorrhizal symbiosis, i.e. ectomycorrhizal and arbuscular mycorrhizal symbiosis. Both types of mycorrhizae benefit the plants, but each type is more adapted to the other environmental conditions. On the roots of dual mycorrhizal trees, the dominance of one mycorrhizal type over another is switching with the increasing value of environmental factors such as temperature of soil, moisture and nutrient availability. Thus dual mycorrhizal trees are more resistant to shift in habitat conditions including seasonal flooding and/or drought and inhabit ecosystems like floodplains, riparian forests and savanna. In general, dual mycorrhizal trees in compared with the single−type mycorrhizal trees are characterized by greater survival, growth, nutrient uptake and longitude range in both native and invasive range put together, so seems to be more resistant to climate changes. These adaptations are an asset for native trees, but on the other hand, the threat of alien tree species. The general proportion of plant species naturalized outside their native range is significantly higher for plants able to enter the dual mycorrhizal symbiosis than only one type. The similar patterns concerning the invasive tree species. Dual mycorrhizal tree species constitute about one−third of all the invasive tree species, but about twice as many among those, which are invasive in five or more of seven biogeographic regions of the world, including willow, poplar, eucalyptus and acacia species. Most of all, invasive tree species from subtropical and tropical zones, such as eucalyptus and black locust threaten European forests. These trees are well adapted to dry conditions so are less affected than European trees by drought, but their plantations caused the drop in groundwater level, intensify the effects of drought on native trees and reduce the efficiency of surrounding agricultural production. In the context of climate changes and the seasonal drought in Poland, expanding knowledge of interactions among microbial symbionts and tree species is necessary to a better assessment of the future benefits and risk involved in the use of each individual tree species.

Opis:
In this study, the effect of arbuscular mycorrhizal fungus − AMF Rhizophagus intraradices inoculum (prior or with transplanting) to different pepper type (Capsicum annuum L.) cv. Arlequin F1 (long fruits) and Raiko F1 (bell pepper), on plant growth and physiological parameters in response to elevated soil P concentrations from organic greenhouse production with enhanced soil salinity, was investigated. To explain the physiological growth of mycorrhizal inoculated (M) and non-mycorrhizal inoculated (NM) plants, the parameters of fungal root length colonization, shoot concentration of P an N during growth, plant height, width of stem, yield, number of fruit per plant and also the quality parameters of fruits such as soluble solid content (SSC), fruit color, mineral profile, total soluble phenolics (TSP) and antioxidant activity (FRAP), were determined. This study showed that application of AMF in cv. Raiko cultivated in high P saline soil generally enhanced growth, fruit yield and number of fruits per plant when inoculated at planting time in the greenhouse. AM inoculated plants, regardless of the time of application in cv. Arlequin grown under the same conditions, did not have any significant differences in comparison with NM plants. Arbuscular mycorrhizal inoculation has great potential in enhancing the pepper growth and yield even in high soil P, however, because of the complexity and interaction of involved genotypes of pepper and AMF, the method and time of inoculation, the system of pepper production and environmental conditions, as well as assays have to be performed to verify positive effects.

Opis:
The influence of Cd concentration in growing substrate (0, 10, 20, 40 mg·dm⁻³) and AMF colonization of root system on growth, flowering, and Cd accumulation in osteospermum shoots were examined. Cd in the applied concentrations did not affect decorative value of osteospermum, no chlorosis or necrosis were observed on leaf margins frequently visible on leaves of other bedding plants. Cd at higher concentrations (20 and 40 mg·dm⁻³) lowered dry weights of shoots and roots in non-mycorrhizal plants. Mycorrhizal plants were lower and had lower dry weights of shoots and roots. Cd did not affect dry weights of shoots and roots in mycorrhizal plants. The effects of Cd and mycorrhization on flowering of osteospermum were negligible. Cd content of osteospermum shoots increased with the increasing content of Cd in growing substrate. Mycorrhizal plants grown in substrate containing 40 mg Cd·dm⁻³ accumulated more Cd in shoots than non-mycorrhizal plants. Obtained results showed that osteospermum is very tolerant to Cd toxicity and can accumulate great amount of Cd in shoots.
Badania miały na celu określenie wpływu zawartości kadmu w podłożu (0, 10, 20, 40 mg·dm⁻³) i mikoryzy arbuskulamej na wzrost, kwitnienie i akumulację Cd w pędach osteospermum. Cd w zastosowanych stężeniach nie obniżał wartości dekoracyjnej osteospermum, nie powodował chlorozy i nekroz na brzegach liści, wyraźnie widocznych u innych roślin rabatowych. Cd w wyższych stężeniach (20 i 40 mg·dm⁻³) powodował spadek suchej masy części nadziemnych i korzeni roślin niezmikoryzowanych. Rośliny zmikoryzowane były niższe i miały mniejszą suchą masę niż niezmikoryzowane. Cd nie obniżał suchej masy pędów i korzeni roślin zmikoryzowanych. Wpływ Cd i mikoryzacji na kwitnienie osteospermum był nieznaczny. Zawartości Cd w pędach osteospermum wzrastały wraz ze wzrostem zawartości tego pierwiastka w podłożu. Rośliny zmikoryzowane rosnące w podłożu zawierającym 40 mg Cd·dm⁻³ akumulowały znacznie więcej Cd w pędach niż rośliny niezmikoryzowane. Otrzymane wyniki wskazują, że osteospermum można zaliczyć do roślin bardzo tolerancyjnych w stosunku do kadmu i zdolnych do akumulacji znacznych ilości tego pierwiastka w pędach.

The mycorrhizal status of 24 plant species considered as endemic, endangered in Poland and included in the IUCN Red List of Threatened Plants is reported. Selected plants and rhizosphere soil samples were collected in the Tatra Mts (Western Carpathians). Individuals of seriously threatened taxa were obtained from seeds and inoculated with available AM fungal strains under laboratory conditions. AM colonisation was found in 16 plants; 9 species were of the Arum-type, 4 - Paris and 3 taxa revealed intermediate morphology. The mycelium of the fine endophyte (Glomus tenue) and dark septate fungi (DSE) were observed in the material collected in the field. 20 AMF species (Glomeromycota) found in the rhizosphere of the investigated plants were reported for the first time from the Tatra Mts. The results provide information that might be useful for conservation and restoration programmes of these species. Application of AMF in active plant protection projects is discussed.

Opis:
155 rhizosphere soil and root mixtures were collected from under Ammophila arenaria colonizing maritime dunes of the island Bornholm (Denmark) to determine arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota co-existing with this plant. In the laboratory, each mixture was divided into two parts. One part was used to establish a pot culture with Plantago lanceolata as the host plant to initiate sporulation of fungi that had not produced spores in field conditions. In the second part, the numerical and species composition of the spore populations of AMF sporulating in the field was determined. Spores of AMF were found in 70 fieldcollected samples and 134 trap cultures. They represented 26 species and six undescribed morphotypes in six genera of the Glomeromycota. Of them, 20 species and three morphotypes in five genera occurred in the field, and 16 species and three morphotypes in five genera were found in trap cultures. The fungi most frequently revealed were members of the genus Glomus; a total of 17 species and six morphotypes of this genus were recognized. Considering the occurrence of spores in both field samples and trap cultures, the fungi most frequently co-occurring with roots of A. arenaria growing in the dunes of Bornholm were G. irregulare (present in 73.6% of samples), followed by Scutellospora dipurpurescens (19.4%) and Archaeospora trappei (10.3%). However, Glomus irregulare mainly sporulated in trap cultures; spores of this fungus were found in only 0.6% of field samples. Other relatively frequently found species were G. aggregatum (9.0%), G. eburneum (7.1%), Paraglomus laccatum (5.2%), and S. armeniaca (6.5%). The species most abundantly sporulating in the field were G. aggregatum (produced 28.36% of all spores isolated), G. badium (11.00%), and S. dipurpurescens (21.55%).

Opis:
The potential of mycorrhization of lettuce in hydroponic conditions was tested in a two-year experiment carried out in the autumn of 2011 and 2012 in an unheated foil tunnel. The experimental factors were as follows: inoculation of plants with arbuscular mycorrhizal fungi (AMF+ or AMF-), concentration of phosphorus in a nutrient solution (10 or 40 mg dm-3) and the type of substrate (rockwool or coconut coir). The inoculation of plants with arbuscular mycorrhizal fungi of the genus Glomus was performed twice, i.e. while sowing seeds and when planting lettuce plants into mats. The impact of the experimental factors on the degree of colonization of lettuce roots by AMF as well as the yield and nutritional status of plants, expressed as the content of macro- and micronutrients, was studied. The mycorrhizal frequency in roots inoculated with AMF reached 51.36%. The nutrient solution concentration of phosphorus and the type of substrate did not have any significant effect on the mycorrhizal frequency. There were no differences in the yield and content of macronutrients in lettuce leaves between plants inoculated and not inoculated with AMF (AMF+, AMF-). Likewise, there were no differences in the yield caused by different phosphorus levels in the nutrient solution or the types of substrate. Plants growing on rockwool accumulated significantly less P, Ca and Mg in comparison to plants growing on coconut coir. Regarding Ca, this effect was especially pronounced in plants receiving the nutrient solution with a higher concentration of P, i.e. 40 mg dm-3. Mycorrhiza had a significant effect on the content of Cu, Mn and Zn in lettuce leaves. Inoculated plants were characterized by a lower content of these micronutries compared to plants grown without AMF. With respect to Mn, this effect was particularly evident in plants grown on rockwool.

Opis:
Apple scar skin viroid (ASSVd) is a serious pathogen of apple fruits that results in severe loss in apple production. Up to nowadays, many ASSVd management options are applied to resist the disease, but the diserable resulits are not achieved. Therefore, this study was conducted in 2010–2012 at experimental field of Penglai City, Shandong Province, China (E 120°57’22’’, N 370°38’33’’) to investigate whether arbuscular mycorrhizal (AM) Glomus versiforme protects Red Fuji apple trees (Malus × domestica Borkh) against apple scar skin viroid. Red Fuji apple trees were inoculated with Glomus versiforme and then potential protection mechanism was explored and compared to noninoculated plants. The results showed that inoculation with Glomus versiforme significantly increased root length colonization rate and clearly decreased the percentage of disease severity of apple scar skin disease. Compared to non-inoculated plants, Glomus versiforme obviously enhanced total nitrogen and phosphorus concentrations in leaves. Root colonization by Glomus versiforme induced an increase in defense-related enzyme activities in fruits, such as the enhanced activities of catalase, ascorbate peroxidase, chitinase and glucanase. Significant differences in acid content of fruit and fruit yield were observed as apple roots were colonized by Glomus versiforme. It is therefore concluded that Glomus versiforme can be regarded as a biocontrol agent to protect apple trees against the infection with ASSVd.
Wiroid bliznowatości skórki jabłek (ASSVd) jest poważnym patogenem jabłek powodującym znaczne straty w ich produkcji. Obecnie stosuje się wiele opcji kontrolowania ASSVd w celu uzyskania odporności na chorobę, ale nie osiągnięto jeszcze pożądanych rezultatów. Niniejsze badanie przeprowadzono w latach 2010–2012 na polu doświadczalnym miasta Penglai, prowincja Shandong w Chinach (E 120°57’22”, N 370°38’33”) w celu zbadania, czy mikoryza abuskularna (AM) Glomus versiforme chroni jabłonie Red Fuji (Malus × domestica Borkh) przed wiroidem bliznowatości skórki jabłek. Jabłonie Red Fuji zaszczepiono Glomus versiforme a następnie badano mechanizm potencjalnej ochrony oraz porównano go z roślinami nieszczepionymi. Wykazano, że inokulacja Glomus versiforme istotnie zwiększyła szybkość kolonizacji korzeni oraz wyrażnie zmniejszyła procent ostrej choroby bliznowatości skórki jabłek. W porównaniu z roślinami nieszczepionymi, Glomus versiforme wyrażnie wzmagał stężenia całkowitego azotu i fosforu w liściach. Kolonizacja korzeni przez Glomus versiforme powodowała wzrost aktywności enzymatycznej związanej z mechanizmem obronnym, np. wzmożoną aktywność katalazy, peroksydazy askorbinianowej, chitynazy oraz glukanazy. Zaobserwowano istotne różnice w zawartości kwasów oraz plonie owoców w miarę kolonizowania korzeni jabłoni przez Glomus versiforme. Można więc wyciągnąć wniosek, że Glomus versiforme może być uważany za czynnik bio-kontroli chroniący jabłonie przed zakażeniem ASSVd.

Opis:
The ontogenetic development and morphological properties of spores of two species of arbuscular mycorrhizal fungi (Glomeromycota) of the genus Glomus, G. claroideum and G. spurcum, are described and illustrated. Spores of the two species were not earlier found in Poland, and this paper is the first report of the occurrence of G. spurcum in Europe. In one-species pot cultures with Plantago lanceolata as the host plant, the mycorrhizae of G. claroideum consist of arbuscules, vesicles, as well as intra- and extraradical hyphae staining intensively with trypan blue. Glomus spurcum mycorrhizae were not recognized, because many attempts to establish one-species cultures of this fungus failed. Additionally, the distribution of both the fungi in the world is presented.

China aster and gaillardia are flowering plants with high economic importance in floriculture. In the present investigation, response of China aster and gaillardia seedlings to inoculation with the arbuscular mycorrhizal fungus Funneliformis mosseae + the plant growth-promoting rhizobacterium Bacillus sonorensis was studied by growing in multipots (pro trays). The germination percentage and plant growth parameters: length of shoots, roots and whole seedlings, stem diameter, biovolume index, plant strength, vigor index, dry weight and nutrient uptake, were analyzed 60 days after sowing. The microbial parameters, mycorrhizal root colonization and spore count, and the population of B. sonorensis in the substrate were also determined. The results brought out that growth of inoculated seedlings was significantly improved as compared to uninoculated seedlings. Based on the plant growth and microbial parameters studied, it was concluded that inoculating the substrate in pro trays with the microbial consortium results in producing vigorously growing seedlings.

Opis:
This study presents root colonization of Deschampsia cespitosa growing in the immediate vicinity of a former Pb/Zn smelter by arbuscular mycorhizal fungi (AMF) and dark septated endophytes (DSE) at different soil depths. AMF spores and species distribution in soil profile were also assessed. Arbuscular mycorrhiza (AM) and DSE were found in D. cespitosa roots at all investigated soil levels. However, mycorrhizal colonization in topsoil was extremely low with sporadically occurring arbuscules. AM parameters: frequency of mycorrhization of root fragments (F%), intensity of root cortex colonization (M%), intensity of colonization within individual mycorrhizal roots (m%), and arbuscule abundance in the root system (A%) were markedly higher at 20–40, 40–60 cm soil levels and differed in a statistically significant manner from AM parameters from 0–10 and 10–20 cm layers. Mycorrhizal colonization was negatively correlated with bioavailable Cd, Pb and Zn concentrations. The number of AMF spores in topsoil was very low and increased with soil depth (20–40 and 40–60 cm). At the study area spores of three morphologically distinctive AMF species were found: Archaeospora trappei, Funneliformis mosseae and Scutellospora dipurpurescens. The fourth species Glomus tenue colonized roots of D. cespitosa and was observed in the root cortex at 20–40 and 40–60 soil depth, however, its spores were not found at the site.

Opis:
Murraya koenigii L. (family: Rutaceae), commonly referred to as curry leaf, is a highly valued plant due to its aroma and medicinal features. Two dominant AM species Glomus mosseae and Acaulospora laevis were isolated from the rhizospheric soil of M. koenigii. A pot experiment was performed to verify the interactive potential of G. mosseae and A. laevis alone or in combination with Pseudomonas fluorescens on M. koenigii. Various morphological and biochemical parameters were measured after 120 days. Overall results suggest that all co-inoculation treatments showed beneficial effects on all the growth, physiological and oil content. The overall results demonstrate that the co-inoculation of bioinoculants, like P. fluorescens with AM fungi, promotes higher AM colonization and spore number enhancing the nutrient acquisition, especially phosphorus (P), improving the rhizospheric condition of soil.

Physalis peruviana is one of the most promising tropical fruit plants because of its rapid growth, high yield, and nutritional quality. Th is study was designed to investigate plant development under heavy metal contamination (Cd, Pb) and responsiveness to arbuscular mycorrhizal fungi (AMF) colonization by Rhizophagus clarum and Claroideoglomus claroideum. Th e antioxidant capacity, total lipid content and fatty acid profi le in fruits, accumulation of Cd and Pb in diff erent plant parts, plant dry biomass, and mycorrhizal colonization were determined. As a result of inoculation, a considerable reduction in Cd and Pb in the fruits was observed, compared with non-inoculated plants. Th e fruit number and dry weight increased in plants associated with C. claroideum. Th ese plants also showed higher acid phosphatase activity, root protein accumulation and glomalin production. Th e type of antioxidant defense was AMF strain-dependent. Antioxidant activity and H2O2 neutralization were enzymatic rather than non-enzymatic processes in the fruits of C. claroideum plants compared with those forming an association with R. clarum. Mycorrhizal establishment changed the composition and concentration of fruits’ fatty acids. Th e ratio of unsaturated fatty acids was increased. With respect to the accumulation of bioactive compounds in golden berry the present fi ndings are important for obtaining the optimum benefi ts of mycorrhizal association under unfavorable conditions.

Opis:
The significance of root colonization by mycorrhizal fungi for the growth and development of Helichrysum arenarium was investigated in two independent experiments. In the first experiment the association of root colonization level with the pluviothermal conditions within the growing season and the age of a natural plant population was analyzed. In the second one, under controlled conditions, the influence of artificial inoculation with the arbuscular fungus Glomus intraradices on the features of plants raised from achenes was studied. It was shown that hydrothermal conditions during blooming period had a greater influence on reproduction processes of sandy everlasting than both the population age (the secondary succession progress) and the level of root colonization by mycorrhizal fungi. High amount of precipitation at plant generative development phase positively influences the potential and actual fertility of ramets. The presence of arbuscular fungus in the soil favors the growth and development of sandy everlasting specimens at their early growing stages: they have a better-developed root system and a greater photosynthetic area.
W dwóch niezależnych eksperymentach poddano ocenie znaczenie kolonizacji korzeni Helichrysum arenarium przez grzyby mikoryzowe, dla wzrostu i rozwoju roślin. W pierwszym doświadczeniu badano powiązanie stopnia kolonizacji korzeni z warunkami pluwiotermicznymi okresu wegetacji i wiekiem naturalnej populacji rośliny. W drugim doświadczeniu, w warunkach kontrolowanych, analizowano wpływ sztucznej inokulacji grzybem arbuskularnym Glomus intraradices na cechy roślin pozyskanych z siewu niełupek. Wykazano, że warunki termiczno-wodne w okresie kwitnienia kocanek piaskowych mają większy wpływ na procesy reprodukcyjne niż wiek populacji (zaawansowanie sukcesji wtórnej) oraz stopień ich kolonizacji przez grzyby mikoryzowe. Duża ilość opadów w okresie rozwoju generatywnego roślin korzystnie wpływa na płodność potencjalną i rzeczywistą ramet. Obecność w podłożu grzyba arbuskularnego sprzyja wzrostowi i rozwojowi kocanek piaskowych we wczesnych stadiach rozwojowych – mają one lepiej wykształcony system korzeniowy i większą powierzchnię asymilacyjną.

Opis:
Mycorrhizal fungi, algae and cyanobacteria are some of the most important soil microorganisms and major components of a sustainable soil-plant system. This study presents for the first time evidence of the impact of green alga and cyanobacterium solely and in combination with arbuscular mycorrhizal fungi (AMF) on plant-antioxidant capacity. In order to provide a better understanding of the impact of AMF and soil microalgae on Ocimum basilicum L. performance, changes in the pattern and activity of the main antioxidant enzymes (AOEs), esterases and non-enzymatic antioxidants including phenols, flavonoids, ascorbate, and α-tocopherols were evaluated. The targeted inoculation of O. basilicum with AMF or algae (alone and in combination) enhanced the antioxidant capacity of the plants and the degree of stimulation varied depending on the treatment. Plants in symbiosis with AMF exhibited the highest antioxidant potential as was indicated by the enhanced functions of all studied leaf AOEs: 1.5-, 2- and more than 10-fold rises of superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione reductase (GR), respectively. The greatest increase in the total esterase activity and concentration of phenols, flavonoids and ascorbate was marked in the plants with simultaneous inoculation of mycorrhizal fungi and the green algae. 2,2-diphenyl-1-pycril-hydrazyl (DPPH) free radical scavenging method and ferric reducing antioxidant power (FRAP) assay proved the increased plant antioxidant capacity after co-colonization of green algae and mycorrhizae.
