Opis:
This study examines the influence on growth parameters, in particular the morphological features of the root system, of 1-year-old European beech seedlings cultivated in containers with two different densities. The experiment was conducted in the container nursery in Skierdy (Forest District of Jabłonna) in spring 2011. After 10 months of cultivation in Hiko polyethylene containers, above- and below-ground parts of the seedlings were measured. The measurements of the root system were conducted with a scanner and the WinRHIZO software. No influence due to the seedling density on either shoot height or thickness was observed, but instead the research showed that different seedling densities affected the development of root systems. The mean root thickness and dry mass of the European beech seedlings were significantly higher at the lower density. The influence of seedling density on the development of root mass deserves special attention as it is the most important factor affecting future growth of the seedlings during cultivation. This tendency also suggests that the amount of nutrients allocated to shoot development may be higher in order to improve the efficiency of photosynthesis. At both densities, differences in biomass accumulation affected the root-toshoot ratio. In seedlings cultivated at the lower density, the increased dry root matter of the seedlings resulted in a significant increase in the root-to-shoot ratio. This may cause a potential growth advantage of these seedlings after they are planted and may thus result in a more productive cultivation.

Opis:
Pinus sylvestris L. seedlings grown for 12-17 months in pure culture after inoculation with S and P strains of Heterobasidion annosum (Fr.) Bref. were studied with the help of light and transmission electron microscopy. Standardized inoculation procedure and uniform in vitro conditions allowed evaluation of the host/pathogen interactions. Necrotic reaction of the bark cells associated with the accumulation of dark-stained material in vacuoles, and lignification of their walls in root regions in proximity to mycelium were the common host reaction. Hypertrophy of the bark cells in areas invaded by hyphae caused a tension that was responsible for strong deformation of the bark cells. Injury to the vascular cambium resulted in formation of barrier zone parenchyma and abnormal xylem elements. High amount of polyphenolic material accumulated in new formed parenchyma cells was an effective chemical “barrier” to the centripetal spread of hyphae. Resin-plugged tracheids and row parenchyma cells rich in polyphenolic material were common in wood areas colonized by the fungus.

Opis:
Prepenetration and penetration phenomena after inoculation of roots of Pinus sylvestris seedlings grown in vitro with the P-, S- and F-group isolates of Heterobasidion annosum were observed using scanning electron microscop. There were no differences in the behaviour of hyphae and in the appearence of mycelia formed by the three IS-group isolates. Four types of the root penetration by hyphae were observed. In the first, the entrace of hypha into root was achieved throught tiny pore formed in walls of the cortical cells. In the second, swellings resembling appressoria were formed by the hyphal tips at the points of contact with the root surface. In the third, the hyphae penetrated cells through holes in eroded areas of roots, and in the fourth by the natural crevices at points of the cortical cell junctions. It is concluded that the different frequencies of the four types of penetration observed after inoculation with isolates of the three IS group should be carefully explained in term of their different pathogenic and saprobic capabilities on pine.

Opis:
Grapevine seedlings Vitis vinifera were grown in a greenhouse under optimum conditions (soil moisture ca 70%) and under drought stress (soil moisture ca 35%). In addition, some of the plants subjected to drought underwent subsequent regeneration under optimum conditions. Drought stress caused accumulation of total phenolic compounds in grapevine roots, which may indicate that these compounds play an important role in the adaptation of roots to growth under stress conditions. Phenolic acids found in the roots occurred in the ester-bound form only. p-coumaric acid was present in the highest concentrations (6.2 to 10.5 µg/g fresh matter). The content of ferulic acid was lower, ranging from 2.4 to 4.6 µg/g fresh matter. The lowest concentration in grapevine roots was achieved by caffeic acid (2.4 to 2.9 µg/g fresh matter). The levels of p-coumaric and ferulic acids in roots rose significantly under the drought stress, while the concentration of caffeic acid increased during the post-drought recovery period. This may suggest that some of the phenolic acids protect plants under stress conditions. All the extracts from grapevine roots had antioxidative properties, but the antiradical activity of the extracts obtained from roots subjected to drought stress was inferior to the control. The same extracts were also characterised by depressed reducing power. The results imply that tolerance of grapevine to soil drought may be associated with the value of antioxidative potential in root tissues of these plants.

Opis:
Secondary plant substances - glucosinolates and saponins reduced seed germination and seedling growth of lettuce. Saponins showed greater inhibitory effect on both germination and growth of lettuce seedlings than glucosinolates. The effect depended on the concentration of these compounds in the ground. Tested compounds caused abbreviation of roots, browning their tips and prevented root hair development.
Testowano wpływ roślinnych metabolitów wtórnych: saponin lucerny i glukozynolanów rzepaku na kiełkowanie nasion sałaty. Stwierdzono hamujący wpływ obu badanych związków na kiełkowanie. Znacznie silniejsze działanie wykazywały saponiny, przy czym efekt ten zależny był od ich stężenia w podłożu. Badane związki wpływały nie tylko na liczbę skiełkowanych nasion, ale również na wygląd siewek (skrócenie korzonków, brunatnienie ich końców, brak włośników).

Opis:
Lupine diseases caused by pathogenic fungi constitute a serious problem in agriculture. They lead to partial yield loss and deterioration of crop quality through the changes in biochemical composition of seeds or their contamination with mycotoxins. Some of common lupine diseases are fusarioses caused by Fusarium oxyspomm f. sp. lupini. Morphometric and metabolic changes were investigated in yellow lupine seedlings infected with F. oxyspomm f. sp. lupini. It was found that infection caused temporary inhibition of seedling growth, overcome at later development, and activation of ß-glycosidase and peroxidases. The changes in enzymes activity indicate the induction of defense mechanism against F. oxyspomm f. sp. lupini and inhibition of pathogen spread.
Choroby łubinu powodowane przez grzyby chorobotwórcze stanowią poważny problem w rolnictwie. Prowadzą do zniszczenia części plonu oraz pogorszenia jego jakości, poprzez zmiany w składzie biochemicznym nasion lub zakażenie ich mykotoksynami. Do powszechnie występujących chorób łubinu zaliczane są fuzariozy powodowane przez Fusarium oxysporum f. sp. lupini. Badano zmiany morfologiczne oraz metaboliczne w siewkach łubinu żółtego infekowanych F. oxysporum f. sp. lupini. Stwierdzono, że infekcja spowodowała okresowe zahamowanie wzrostu siewek, przełamane w dalszej fazie ich rozwoju oraz aktywację ß-glikozydazy oraz peroksydaz. Poinfekcyjne zmiany aktywności enzymów wskazują na uruchamianie mechanizmu obronnego względem F. oxysporum f. sp. lupini i zahamowanie rozprzestrzeniania się patogena.

Opis:
The experiments were carried out on Lotus corniculatus (L.) seedling root explants of the cultivar varieties Skrzeszowicka, Caroll A10 and strain 175. Callus formation and shoot regeneration were the major explant response depended mainly on of the studied genotype and used plant growth regulators (PGRs). Primary cortex of proximal and distal end of explant was the most active tissue for callus proliferation. For shoot primordia differentiation deeper zones of cortex took a part. The process of meristematic centre initiation was not uniform and various level of shoot differentiation events were observed not earlier than 3 weeks of culture. Usually, the shoot primordia regeneration began on proximal rather than distal end of the explant. BAP rather than urea derivatives stimulated shoot proliferation in extended cultures. Increasing of BAP and TDZ concentrations brought about the explant polarity and expansion of the meristematic zones. The explant position in root did not have significant influence on the number of regenerated shoots. The cultures only had better bud formation by TDZ when compared to BAP. BAP stimulated bud formation and development of the shoots from them. Short term of TDZ treatment of explants stimulated meristem formation which developed into buds and shoots. CPPU stimulated callus proliferation and bud formation when explants pretreatment was prolonged from 12 to 36 hrs.

Opis:
While each individual root responds to such environmental factors as light or gravity the question arises how these reactions subordinate to the whole root system, which is supposed to maintain its primary functions. Data presented here confirm that in cucumber the gravity and light modulate the growth direction of the lateral roots subunits of the system. Another important factor affecting behavior of lateral roots is an orientation of the main root. These facts all together suggest that the root system functions as an integrated entity, capable of adapting its architecture to changing environmental conditions. Its flexibility, based on unknown signaling network, guarantees optimal functioning of the system.

Opis:
The experiments were carried out in the years 2002 and 2003 on parsley seeds of 6 cultivars: Alba, Berlińska, Cukrowa, Kinga, Lenka, and Vistula. Mycological analysis of parsley seeds showed that the most common inhabitans were fungi from genus Alternaria (mainly A. alternata and A. radicina) and Fusarium, especially F. avenaceum and F. oxysporum. During the glasshouse investigations fungi Alternaria radicina, A. alternata and Fusarium avenaceum were the main reason for parsley damping-off. The highest number of infected seedlings was observed for Berlińska and Kinga, because in both years of experiments these cultivars had the lowest number of healthy seedlings. The highest number of healthy seedlings had cultivars Alba and Lenka, especially in the second year of experiments. In the field experiments not only fungi from genus Alternaria and Fusarium were the most often isolated from diseased parsley seedlings. Fusarium oxysporum was more often isolated from diseased field seedlings than from glasshouse parsley seedlings. Other fungies isolated often from parsley seedlings cultivated in the field were: Pythium spp., Rhizoctonia solani, Cylindrocarpon destructans and Stemphylium botryosum.
Badania przeprowadzono w latach 2002 i 2003 na sześciu odmianach pietruszki korzeniowej: Alba, Berlińska, Cukrowa, Kinga, Lenka i Vistula. Podczas analizy mikologicznej nasion stwierdzono, że najliczniej występującymi są grzyby z rodzaju Alternaria (głównie A. altrnata i A. radicina) oraz Fusarium (F. avenaceum i F. oxysporum). W doświadczeniach szklarniowych głównymi sprawcami zamierania siewek były grzyby: A. radicina, A. alternata oraz Fusarium avenaceum. Najsilniej porażone były siewki odmian Berlińska i Kinga. Najwięcej siewek zdrowych, zwłaszcza w drugim roku badań było w przypadku odmian Alba i Lenka. W doświadczeniach polowych z zamierających siewek izolowano obok grzybów z rodzajów Alternaria i Fusarium, także inne gatunki grzybów patogenicznych. Z siewek pobranych z pola uzyskano większą liczbę izolatów Fusarium oxysporum niż z siewek ze szklarni. Także dość licznie wystąpiły grzyby: Pythium spp., Rhizoctonia solani, Cylindrocarpon destructans i Stemphylium botryosum, które mogą być sprawcami zamierania siewek pietruszki.

A vanishing species in Poland - Plantago maritima L. was regenerated in vitro from tips of shoots (obtained in vitro) and from different explants of 4-week-old seedlings: seedling tips, hypocotyls, cotyledons, roots. Murashige and Skoog basal medium, supplemented with 0.6 pM indole-3-acetic acid in combination with cytokinins 6-benzyladenine, zeatin or kinetin, was used. The plants obtained in the result of micropropagation were normal in appearence. It was proved that Plantago maritima species was amenable to propagation from different kinds of explants. The method may be of significance for protection of sea plantain.

Opis:
Effects of 62 isolates (of 41 taxa) of fungi on growth of 1-year-old oak (Quercus robur) seedlings were studied in an inoculation experiment. The fungi were isolated from roots of 80–96-year-old Q. robur that had been subjected to periodic flooding and had symptoms of oak decline. The fungal genera included Alternaria, Aspergillus, Calonectria, Chaetomium, Cladosporium, Clonostachys, Corynespora, Cylindrocarpon, Dicyma, Geotrichum, Ilyonectria, Isaria, Metarhizium, Oidiodendron, Ophiostoma, Pezicula, Phialocephala, Phialophora, Pyrenochaeta, Sporendocladia, Sporothrix, Thelonectria, Trichoderma and Trimmatostroma. Mycelial colonies of fungi growing in potato-dextrose broth were used for soil inoculation. Plant growth was assessed 2 years after inoculation, when the plants were 3 years old. Stem lengths, and dry weights of stems, roots and leaves were measured. Stem growth was inhibited by 31 isolates (50%) and root growth by 12 isolates (19%). Stem growth was stimulated by two isolates (3%) and root growth by 17 isolates (27%). The overall ratio of inhibitors to stimulants was 2.1. The proportion of taxa that inhibited stem growth was 16 times greater than that which promoted stem growth. The proportion of taxa that promoted root growth was only 1.5 times greater than that which inhibited root growth. The structure of the fungal communities in periodically flooded oak forests suggests that they are more likely to inhibit than to promote vigour in oaks.
