Opis:
Actinomycetes are considered to be the biggest producer of bioactive compounds which are expected to have antifungal activity for controlling many fungi such as Rhizoctonia solani. The objective of this study was to obtain potential soybean rhizosphere actinomyc- etes as a biocontrol agent for R. solani which cause damping-off disease both in vitro and in vivo, including their ability to produce siderophore, chitinase, and HCN. Out of 26 isolates, 18 (56%) showed diverse antifungal activities against R. solani with percentages of inhibi- tion radial growth (PIRG) from 18.9 to 64.8%, as evaluated by a dual culture method. Ten isolates with the strongest antifungal activity were numbered for further characterization. All the tested isolates were not antagonistic towards Bradyrhizobium japonicum. These iso- lates were able to suppress damping-off disease caused by R. solani in the greenhouse exper- iment. Isolate ASR53 showed the highest disease suppression, 68% and 91% in sterile and non-sterile soil, respectively. Based on 16S rRNA sequence analysis this isolate belonged to Streptomyces violaceorubidus LMG 20319 (similarity 98.8%) according to GenBank data base available at www.ncbi.nlm.gov.nih. Furthermore, isolate ASR53 had significantly longer roots and shoots, as well as greater fresh and dry weights of seedlings than the con- trol. Crude extract derived from ASR53 isolates contained 10 dominant compounds that were biologically active against fungal pathogens. Thus, this study suggests that the applica- tion of potential actinomycetes of the soybean rhizosphere can act as a promising biocon- trol agent against damping-off disease caused by R. solani.

Opis:
The current study aimed to evaluate the biodiversity and antagonistic potential of 22 endophytic fungal species belonging to 10 endophytic genera, namely Acremonium, Alternaria, Aspergillus, Fusarium, Gliocladium, Nigrospora, Penicillium, Pochonia, Scopulariopsis, and Stachybotrys, along with 2 morphospecies of mycelia, namely a yellow sterile septate mycelium (YSSM) and a dark sterile septate mycelium (DSSM), living within healthy Triticum aestivum L. against nine wheat pathogenic fungi identified as Alternaria alternata, Alternaria cichorii, Alternaria dianthi, Alternaria sonchi, Aspergillus petrakii, Curvularia penniseti, Fusarium oxysporum, Fusarium semitectum, and Fusarium solani obtained from naturally infected plants. The highest count and frequency in T. aestivum were recorded for Fusarium subglutinans (n = 81 and Rf = 34.91%) followed by DSSM (n = 32 and Rf = 13.79%). In vitro DSSM studies showed the highest antagonistic activity of 56.52% reduction against A. petrakii, while F. subglutinans inhibited F. semitectum by 72.97%. These two endophytic isolates were then selected as fungal bioagents to control root rot disease in wheat caused by A. petrakii and F. semitectum under greenhouse conditions. Wheat plants growing from seeds inoculated with DSSM were more resistant to root rot disease in soil infected with A. petrakii, and they showed reduced root rot severity percentage (15.56%) and disease index (0.27) compared to the values of 40% and 1.13, respectively, for these parameters in untreated plants. Furthermore, treatment of seeds with F. subglutinans before planting in soil infected with F. semitectum reduced the disease severity percentage and the disease index from 50% and 2.20 to 20% and 0.47, respectively. These endophytic fungi also markedly increased the growth parameters (length, fresh weight, and dry weight of shoots and roots) of wheat plants growing in soils infected with these phytopathogens. The present study showed that wheat is a promising ecological niche for different fungal endophytes that assist their host plants to survive and resist the harmful effects of phytopathogenic fungi, improve wheat growth, and develop fungal strains as biological control solutions against wheat diseases.

This paper presents results on the restoration of Scots pine stands established on post-agricultural lands undergoing conversion into mixed stands. Sessile oak (Quercus petraea), common beech (Fagus sylvatica) and small-leaved lime (Tilia cordata) seedlings were planted in artificially created gaps (0,02 ha to 0,05 ha each) cut in six experimental plots (Forest Districts: Bielsk, Krynki, Sobibór, Dobieszyn, Skrwilno and Łupawa) located in 20–25-years-old pine stands. The experimental plots were spread across northern, central and eastern Poland and affected by root-rot fungus (Heterobasidion annosum). Nine years after planting, the number of individual trees and shrub species, their height sum and average height were calculated for fenced artificial gaps (LSO) as well as non-fenced artificial gaps (LSN) and compared to natural gaps (LN) and non-disturbed neighboring stands (D). Results were calculated separately for the planted species (oak, lime and beech) but combined for all other species. The results indicate satisfactory restoration in all of the investigated plots except in Krynki, which is located in a relatively poor site. Significant differences appeared between height sum as well as average height of planted species in fenced compared to non-fenced gaps. Furthermore, in both, natural and artificial gaps, the species composition of the young generation was enriched with natural regeneration of pioneer species, mainly silver birch (Betula pendula), rowan (Sorbus aucuparia) and aspen (Populus tremula).

Opis:
Throughout the world, charcoal rot, caused by Macrophomina phaseolina, is one of the most destructive and widespread diseases of crop plants such as soybean. In this study, the biological control capability of 11 Trichoderma spp. isolates against M. phaseolina was investigated using screening tests. Among all the tested Trichoderma spp. isolates, inhibition varied from 20.22 to 58.67% in dual culture tests. Dual culture, volatile and non-volatile tests revealed that two isolates of Trichoderma harzianum (including the isolates T7 and T14) best inhibited the growth of M. phaseolina in vitro. Therefore, these isolates were selected for biocontrol of M. phaseolina in vivo. The results of greenhouse experiments revealed that disease severity in the seed treatment with T. harzianum isolates was significantly lower than that of the soil treatment. In most of the cases, though, soil treatment with T. harzianum resulted in higher plant growth parameters, such as root and shoot weight. The effects of T. harzianum isolates on the activity of peroxidase enzyme and phenolic contents of the soybean root in the presence and absence of M. phaseolina were determined in greenhouse conditions. Our results suggested that a part of the inhibitory effect of T. harzianum isolates on soybean charcoal rot might be related to the indirect influence on M. phaseolina. Plant defense responses were activated as an elicitor in addition to the direct effect on the pathogen growth.

Opis:
Phenylalanine ammonia lyase (PAL) is a specific branch point enzyme of primary and secondary metabolism. It plays a key role in plant development and defense mechanisms. Phenylalanine ammonia lyase from Hevea brasiliensis (HbPAL) presented a complete open reading frame (ORF) of 2,145 bp with 721 encoded amino acids. The sequence alignment indicated that the amino acid sequence of HbPAL shared a high identity with PAL genes found in other plants. Phylogenetic tree analysis indicated that HbPAL was more closely related to PALs in Manihot esculenta and Jatropha curcas than to those from other plants. Transcription pattern analysis indicated that HbPAL was constitutively expressed in all tissues examined, most highly in young leaves. The HbPAL gene was evaluated by quantitative real-time PCR (qRT-PCR) after infection with Rigidoporus microporus at 0, 12, 24, 48, 72 and 96 hours post inoculation. The expression patterns of the PAL gene differed among the three rubber clones used in the study. The transcription level of the white root rot disease tolerant clone, PB5/51 increased sharply during the latter stages of infection, while it was relatively subdued in the white root rot disease susceptible clones, RRIM600 and BPM24. These results suggest that the HbPAL gene may play a role in the molecular defense response of H. brasiliensis to pathogen attack and could be used as a selection criterion for disease tolerance.

This study was done to assess the antifungal effect of some biocontrol agents effective microorganisms (EMs1), Pseudomonas fluorescences, and Bacillus pumilus, titanium dioxide (TiO2) nanoparticles, black cumin and wheat germ oils as well as the recommended fungicide (flutolanil) against root rot of tomato. Moreover, gas chromatography-mass spectrometry (GC-MS) examination was completed to identify the bioactive compounds in plant oils (dark cumin and wheat germ). Also the impact of these medicines on some biochemical and growth parameters of tomato was examined. Flutolanil was the best treatment followed by dark cumin, TiO2, EMs1, Pseudomonas fluorescens, Bacillus pumilus and wheat germ oil, individually in both test seasons. The outcomes demonstrated a marked increase in each biochemical character (chlorophyll substance, peroxidase and polyphenoloxidase) and plant development (height and fresh and dry weight) under all the tried treatments in comparison to the controls.

Opis:
Zucchini is a very valuable vegetable, easy to grow both in the field and under covers but it is often attacked by soil-borne fungi. The investigations were carried out in a farm near Lublin where three zucchini cultivars: Astra, Atena and Soraya, were grown in a tunnel and in the field in 2008-2009. Plants with stem and root rot were collected for laboratory tests. Mycological analysis showed that the predominant fungi were F. culmorum, F. equiseti and F. oxysporum. More Fusarium colonies were isolated from the roots of zucchini grown in the tunnel. In the pathogenicity test, all tested isolates of F. culmorum, F. equiseti and F. oxysporum proved to be pathogenic to zucchini seedlings, causing stunting, stem and root rot. The highest disease index was noticed in the combination with F. culmorum isolate fck61.

Opis:
During the last years an alarming dieback has occurred in 20 to 40 years old first-rotation pine stands (Pinus sylvestris L.) on mine sites, caused by the white rot fungus Heterobasidion annosum (Fr.) Bref. First thinning opens the infection path so that up to now 30 to 89 % of afforestations in different mining areas are affected. Infestation risk increases with rising pH of the top soil (0-30 cm). The mean pH(H2O) of the infestation foci is 6.2, whereas it is below 5.0 in uninfected stands. Common practise of lime amelioration speeds up the infection. Furthermore, soil water availability (PAWC) has a significant impact on the course of disease. The plant available water (0-100 cm soil depth) of dieback gaps is about 80 mm. In contrast, the water storage capacity of unin-fected reference plots falls below 50 mm.
W ostatnich latach wystąpiło niepokojące zjawisko zamierania 20-40 letnich sosen (Pinus sylvestris L.) pierwszej rotacji na terenach pokopalnianych, spowodowane przez korzeniowca wieloletniego (Heterobasidion annosum (Fr.) Bref.). Pierwsze przerzedzenie otwiera drogę zakażenia tak, że do tej pory objęło ono od 30 do 89% zadrzewień na różnych obszarach pogórniczych. Odnotowano wzrost ryzyka infekcji wraz ze wzrostem odczynu powierzchniowego poziomu gleb (0-30 cm). Średnia pH(H2O) z ognisk zakażenia to 6,2, podczas gdy na powierzchniach niezakażonych wyniosła poniżej 5,0. Powszechną praktyką zahamowania tempa zakażenia jest wapnowanie gleb. Ponadto, na przebieg choroby znaczący wpływ wywiera dostępność wody w glebie (PAWC). Dostępna woda dla roślin (0-100 cm gł.) na obszarach zamierania to ok. 80 mm. W przeciwieństwie, na obszarach nie zainfekowanych zdolność zatrzymywania wody spada poniżej 50 mm.

Badania przeprowadzono w latach 2004–006 na polach Hodowli Roślin Danko w Kopaszewie, woj. wielkopolskie. W każdym sezonie wegetacji w fazie dojrzałości późno-woskowej ziarna (87 w skali Tottmana (1987) oceniano porażenie korzeni i dolnych międzywęźli źdźbeł. Odsetek źdźbeł wykazujących objawy chorobowe wynosił od 32 (Rajtar) do 85% (Deresz) w 2004 roku, od 44 (Gniady) do 93% (Breton) w 2005 roku i od 8 (Cwał) do 34.5% (Rajtar) w 2006 roku. Średnio po 3 latach badań udział źdźbeł z objawami nekrozy korzeni i podstawy źdźbeł wynosił od 42% w przypadku odmiany Rajtar do 64 w przypadku odmiany Breton. Analiza mikologiczna chorych roślin wykazała, że przyczyną chorób podsuszkowych owsa, w każdym sezonie wegetacji były grzyby z rodzaju Fusarium, a w szczególności gatunek F. culmorum oraz Bipolaris sorokiniana.
The investigations were carried out in 2004–2006 in the plots of Plant Breeding Station in Kopaszewo. Disease symptoms were recorded in each vegetation season at the hard dough stage (87 in the Tottman scale (1987)). The percentage of diseased stems ranged from 32 (Rajtar) to 85% (Deresz) in 2004, from 44 (Gniady) to 93% (Breton) in 2005, and from 8 (Cwał) to 34.5% (Rajtar) in 2006. After a 3-year period the proportion of stems with root rot and stem bases necrosis ranged from 42% in cv. Rajtar to 64% in cv. Breton. A mycological analysis of the diseased plants showed that the causal agents of these diseases in each vegetation season were fungi belonging to Fusarium spp. particulary F.culmorum, and Biopolaris sorokiniana.

Leaves, stem and pneumatophore of Avicennia marina and leaves and stem of Rhizophora mucronata were used as the organic amendments at 0.1, 1 and 5% concentrations in the control of root rot fungi like (Fusarium spp., Rhizoctonia solani and Macrophomina phasoelina) and root knot nematode Meloidogyne javanica on potato. In pot experiments, germination of seeds, shoot length, shoot weight, root length, root weight and number of knots were signifi cantly increased when plant parts like leaves, stem and pneumatophore of A. marina and R. mucronata were used at 1 and 5% concentrations. There was a complete suppression in infection of R. solani and M. phaseolina when A. marina and R. mucronata were used at 5% concentration on potato. Maximum inhibition of knots of M. javanica was observed when powder made from mangrove plant parts was used at 1 and 5% concentrations. Powder from all plant parts, like leaves, stem and pneumatophore, was effective in suppression of root infecting fungi and root knot nematode.

W doświadczeniach wazonowych kiełkowanie nasion, masa pędu, długość korzenia, masa korzenia znacznie zwiększyły się, a liczba narośli zmniejszyła się, kiedy części roślin A. marina i R. mucronata, takie jak liście, łodygi i pneumatofory, stosowano w stężeniu 1 i 5%. Nastąpiło zupełne zablokowanie zakażenia przez R. solani i M. phaseolina, kiedy części roślin A. marina i R. mucronata stosowano w stężeniu 5% w uprawach ziemniaka. Maksymalne zahamowanie narośli wywoływanych przez M. javanica obserwowano, kiedy proszek zrobiony z części roślin namorzynowych stosowano w stężeniu 1 i 5%. Proszek ze wszystkich części roślin, takich jak liście, łodygi i pneumatofory, był skuteczny w blokowaniu działania grzybów porażających korzenie i nicieni Meloidogyne javanica.

A comparative analysis of costs incurred during the application of the traditional method and a „dispersed treatment” method is presented in the paper. It has been demonstrated that the application of the proposed method brings about a significant reduction in costs.

Tolerance of several strains of the P-, S-, and F- intersterility groups of Heterobasidion annosum to low pH and high concentration of aluminium ions was studied on malt extract agar. There were marked intraspecific, but not intergroup, variations in tolerance to both factors. Some strains were relatively tolerant or sensitive to low pH and aluminium, while the others were tolerant to low pH but sensitive to Al. There was no relationship between tolerance of the strains to low pH and their tolerance to aluminium stress.

Opis:
The paper provides a characterisation of nine most important factors predisposing and stimulating the intensity and the scale of their occurrence, as well as risk limits (table 2). Important supplementary information about the intensity of occurrence of four main predisposing factors in forest districts is presented in the form of a table (data as of 2002).

Opis:
Changes in silvicultural and phytopathological parameters have been assessed in a 55−year−old pine stand established on post−agricultural land after 30 years from the application of three types of cutting (selective 10%, line every 4 and every 6 row) in this stand. It has been demonstrated that root rot causes changes in number and volume of merchantable timber of trees when protective treatments to stumps using the fungus Phlebiopsis gigantea are not applied during first improvement cuttings.
