Opis:
There are many serious pests in forest nurseries, which can be killed by entomopathogenic nematodes (EPNs) applied to soil. The paper presents a method of biological control, which is appropriate for destroying harmful insects, and is an alternative to chemicals−based approach. Both, the rules and technical conditions concerning the application of biological preparations for insects control are discussed. Facing the problem of excessive chemicalization, especially in the forest nurseries, the authors, in accordance with EU Directives, reviewed the opportunities for biological methods of forest crops protection against seven of the most harmful species of insects. Selection of EPNs for control of a particular pest insect is based on several factors that include the nematode’s host range, host finding or foraging strategy, tolerance of environmental factors and their effects on survival and efficacy (temperature, moisture, soil type, exposure to ultraviolet light, salinity). The most critical factors are moisture, temperature, pathogenicity for the targeted insect, and foraging strategy. Entomopathogenic Nematodes for Control of Insect Pests from the genera Steinernematidae and Heterorhabditidae cooperating with mutualistic bacteria were described accurately in this paper. They are capable of killing a broad range of insects. Applied to the soil, they can persist long in the environment and moreover they improve the soil quality. However, along with all the benefits, disadvantages of presented method were also discussed. Namely the abiotic conditions, technique, and limitations of their effectiveness. We presented a list of commercially produced EPNs, which are currently in use in Poland. We also reviewed the World’s literature on the successful use of EPNs and discussed aspects of their commercialization. The wider use of biological preparations containing EPNs should be implemented in the near future.

Opis:
Nanoparticles are gaining ever−wider application in plant production (for both agriculture and forestry), in the role of pesticides, as well as stimulators of plant growth and resistance. We sought to determine the efficacy of silver and copper nanoparticles (AgNPs and CuNPs respectively), used as seed dressings or subjected to foliar application, in affording protection from parasitic damping−off disease among soil−grown seedlings of Scots pine in a forest nursery. Experiments also assessed the influence of the nanoparticles on the growth of the plants potentially safeguarded in this way. Nanoparticles were used in seed soaking and foliar spraying at 50 ppm concentration. Pines treated with fungicides (Zaprawa Nasienna T 75 DS, Acrobat MZ 69 WG, Topsin M 500 SC, Gwarant 500 SC, Thiram Granuflo 80 WG and Signum 33 WG) or unprotected at all were used for comparison. In each treatment (AgNPs, CuNPs, fungicides or unprotected), seedlings were inventoried 6 weeks after the sowing and at the end of the growing season, while all individuals on 80 1−m−long segments of seed row were counted. At the end of the growing season, shoot length, root−collar diameter, root length and dry mass of shoots and roots were determined. The seedlings treated with nanoparticles had longer root systems of greater dry mass, but also only more weakly−developed above−ground parts (both height and dry mass being limited) in comparison with young Scots pines that had been fungicide−treated or were unprotected. It resulted in a significantly more favourable ratio between shoot and root masses, where nanoparticle treatment had been applied. The effectiveness of the protection extended to the germination and first−growth stages up to 6 weeks from the time of sowing was furthermore shown to be greatest where AgNPs had been applied, while at the season end there were comparable results among pines treated with either nanoparticles or fungicides. Our results thus indicate that nanoparticles limit damping−off disease in pine seedlings (AgNPs more effectively than CuNPs), with that effectiveness also proving comparable with that noted for the fungicides applied traditionally.

Opis:
Pinus × rhaetica is holoarctic species, which represents mixed morphological features from both P. uncinata and P. mugo. It is a typical species living in peat−bogs in highlands and it is endangered by drainage and the decline of its natural area. By now, the greatest population of peat−bog pine is living in the Wielkie Torfowisko Batorowskie peat−bog, but its health condition is alarming. In Poland P. × rhaetica is placed on the red list of plants and fungi as an endangered species, with a high risk of extinction in the wild. In order to preserve the genetic potential of the population, the national park has taken active protective measures, establishing a conservative nursery. The aim of this study was to determine the potential role of fungi growing on needles of peat−bog pine in health condition. The study was carried out in three conservative pine nurseries in the Góry Stołowe National Park (SW Poland). Needles and dead wood of peat−bog pine were collected in July 2016. Material was decontaminated in 1% surfactant solution of sodium hypochlorite. The next step was the liner of about 0.5 cm pieces of needles of 6 Petri dishes with solidified, acidified PDA medium (agar−potato glucose). The dominant microscopic fungi inhabiting needles are Lophodermium pinastri, isolated from all of the plots, and Truncatella hartigii, which was observed only on Wielkie Torfowisko Batorowskie peat−bog (tab. 1). A much greater diversity of species of fungi characterized that peat−bog (tab. 2).

Opis:
In the nurseries, Scots pine seedlings that show symptoms of the damping−off usually die. Rhizoctonia solani, a rapidly growing fungus, is one of the pathogens that infect the roots of plants. The aims of this study were: (1) to evaluate the susceptibility of R. solani and saprotrophic fungi Mortierella elongata, Trichoderma hamatum and T. rossicum to fungicides, (2) to determine whether yeast isolates can be used as effective inhibitors of the pathogen's growth, and (3) to analyze phylogenetic relationships between filamentous fungi. The Switch 62.5 WG fungicide, containing cyprodinil and fludioxonil, most effectively suppressed the growth of the tested R. solani isolates, but also exerted ecotoxic effects on the analyzed saprotrophs. The R. solani RS 1 isolate did not respond to the presence of azoxystrobin in PDA. Most of the 13 yeast isolates tested in the study inhibited the growth of pathogen colonies, but only one isolate was characterized by inhibitory activity of 59.03% and exerted a strong antagonistic influence on the pathogen. A phylogenetic analysis revealed that the tested isolates represented three clades: 1) T. hamatum, 2) T. rossicum, and 3) R. solani. The phylogenetic tree of M. hamatum and T. rossicum showing their divergence due to mutations did not reflect their speciation.

Opis:
The aim of the study was to compare growth and survival of plug and bare−root seedlings planted at different dates. The experiment was established in 2003 in the Oleśnica Forest District (south−western Poland). Seedlings were planted at four dates: the end of August, September and October 2003 and the beginning of April 2004. The two−factorial experiment comprised eight treatments. It was established in the randomized complete block design in five replications. In each plot a total of 390 seedlings were planted. The objects were measured in the years 2004−2008 and 2013. At first height of all trees was measured using a scaled rod. In 2013 diameter at breast height was measured on all trees and height was measured for some randomly selected individuals. The ANOVA was supplemented with with Tukey's multiple comparison test. The height and diameter distributions in analysed variants were compared with Kolmogorov−Smirnov test. Treatments were found rather not to vary in terms of their survival rates (fig. 1). No variation was found for mean diameters at breast height (tab. 1). The difference between the treatment with the maximum (August planting, bare−root seedlings) and minimum (April planting, bare−root seedlings) tree height equaled 69 cm. No significant differences were recorded between mean heights of trees planted in August, September and October regarding the planting material type. Variation in basal area results both from survival rates and diameter at breast height. Only spring planting of bare−root seedlings was found significantly different from all other variants (tab. 1). Differences in height between the control and the mean for the experiment increased continuously (fig. 4). Scots pine seedlings may be successfully planted in late summer and autumn. Under relatively advantageous conditions, particularly moisture levels, 1 year old bare−root pine seedlings are not inferior to plug seedlings. Plug seedlings tolerate soil drought conditions better than bare−root seedlings. The effect of stress connected with drought after planting, measured by mean height, rather than disappearing, is continuously increasing with age.

Opis:
The possibility of using chemicals in European forestry is extremely limited due to the binding legal regulations and specific conditions concerning the market of plant protection products. This is reflected in the limited availability of active fungicides in forestry. Due to this limitation, practitioners using fungicides in forest nurseries and forest cultivation must have substantial knowledge of the biology of pathogens to ensure satisfactorily effective protection. The work presented here provides an overview of the currently recommended fungicides in Polish forestry as well as the mechanisms of interaction between the active substances and the pathogen, the plant and mycorrhizal fungi. In this paper we also discuss the risk of fungicide resistance, which has been insufficiently explored in the context of forest pathogens.

Opis:
Pedunculate oak (Quercus robur L.) is among the major managed tree species in Europe. In Poland, oak woodlands cover 6.9% of forest area. Furthermore, the significance of native oaks for Polish forestry is rising because the Polish National Forest Strategy predicts a growth of forest cover from 28.5% to 33% by year 2050 with the primary focus on the increase in contribution of deciduous tree species (from 22% to 33%). Therefore, for establishment of new stands, oak seedlings are grown for 2−3 years in forest nurseries. For optimal growth and development all European oak species are critically dependent on ectomycorrhizal fungi. The objective of this study was to describe the temporal dynamics of ectomycorrhizal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery. Experiment was conducted in forest nursery Miranowo (western Poland). The species structure of an ectomycorrhizal community was assessed every 10 or 15 days from May till October. Mycorrhizal colonization of tested seedlings changed from 0 to 85% depending of the time of sampling. Based on combination of morphological and molecular techniques, nine ectomycorrhizal fungal taxa were distinguished. The first ectomycorrhizas formed by Scleroderma verrucosum were detected 50 days after acorns sowing. In the next sampling days ectomycorrhizal community was dominated consecutively by Inocybe curvipes and Hebeloma sacchariolens (with maximum of abundance 60.98 and 75.55%, respectively). The obtained results were strongly influenced by the infection with the fungal biotroph Erysiphe alphitoides and resulted in a dramatic reduction in the abundance of living ectomycorrhizas down to 7.5%. Our investigation revealed that ectomycorrhizal fungal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery is rich in terms of number of species and a temporal changes are very dynamic. Thus we suggest, that in case of pedunculate oak artificial inoculation in general is not necessary for oaks seedlings in nursery practice.

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.

Achieving high quality propagative material is difficult today due to the limited number of pesticides recommended for use. Simultaneously, EU regulations on Integrated Pest Management (IPM) in forest nurseries came into a force, requiring a search for alternative plant protection methods that are safe for humans, animals and the environment. In this paper, we present the possibilities of using bio-fungicides against diseases in forest nurseries, their mechanisms of action, as well as the direction of their development (according to IPM rules). We reviewed the results achieved by different research teams presenting the possibilities and trends in combatting Oomycetes and Fusarium spp. pathogens currently having the most important economic impact.

Opis:
The alkalization of soil is a common phenomenon in forest ground nurseries. Liming, inadequate fertilization and the use of hard water for irrigation are the main reasons for this alkalization. The aim of this study was to investigate the effect of fertilization with aluminium sulphate on soil pH, the activity of selected soil enzymes, efficiency as well as the growth parameters of pine seedlings. The study was conducted in a forest nursery, on a plot with soil pH 6.4 in water and 5.9 in 1MKCl. Such a pH is not conducive to the production of conifer seedlings, particularly pines. Two different doses of aluminium sulphate fertilizer were applied: 740 kg ha-1 and 1110 kg ha-1. Both doses significantly reduced the soil pH, whereas soil enzyme activity did not change. The lower dose had a positive impact on the growth parameters of pine seedlings, while the higher dose led to their deterioration. We observed statistically significant differences in average primary and lateral root lengths, number of short roots, and thickness of the neck root of seedlings. One- and 2-year-old seedlings did not show symptoms of nutrient deficiency and neither did concentrations of the investigated macronutrients and selected micronutrients in needles indicate such. After applying the higher fertilizer dose, we observed a favourable change in the composition of mycorrhizae. Out of the potential seedling pathogens we found Cylindrocarpon spp., Fusarium spp., Phytophthora spp., Pythium spp. and Rhizoctonia solani of which the most frequent were Fusarium oxysporum, Pythium spp. and R. solani. Their occurrence frequency differed between the treatments used in this experiment. This study confirms the positive effects of a low aluminium dose on the performance and growth parameters of pine seedlings. However, on the basis of the conducted experiments, it is difficult to say, whether this positive effect is due to a direct action of aluminium on the seedlings or rather an indirect effect caused by lowering the soil pH, which in turn impacts on mycorrhizae composition and hence pathogen development.

The aim of the study was to assess the effect of the application of Sincocin AL and inoculation with the fungi Hebeloma crustuliniforme or Laccaria bicolor on the growth and level of mycorrhizal colonization of Scots pine seedlings. Sincocin had no effect on the development of biometric parameters of pine seedlings inoculated with L. bicolor, it limited the growth of non−inoculated seedlings and stimulated the growth of the seedlings from the variant with H. crustuliniforme. Sincocin did not cause changes in the proportion of the mycorrhizae formed by H. crustuliniforme or L. bicolor, and affected in different ways (stimulation, inhibition, no effect) the spontaneous formation of mycorrhizae.

Opis:
The paper discusses the biologically active compounds contained in onion (Allium cepa L.) such as thiosulfinates and other organosulfur compounds, saponins and flavonoids as well as evaluates their biological role. Method for biofungicides preparation, whose essential element is an aqueous extract of onion, and the possibility of its application in forest nurseries are presented. Content of polyphenols (quercetin and its derivatives) in a biopreparation responsible for its biological activity is determined as well.

Opis:
Slow Sand Filters (SSF) are a biological method used to protect nursery plants, from pathogen infections which can cause serious diseases in many forest tree species. Thanks to SSF application the number of phytopathogens in nurseries can be significantly reduced, as demonstrated by many field and greenhouse experiments (e.g. in Polish nurseries, and for horticultural crops in Germany and The Netherlands). In this study, the effect of pollution from fertilizers and fungicides used in agriculture (e.g. PCNB) on the efficiency of SSFs was assessed. A quantitative analysis was performed of the copiotrophic and oligotrophic bacterial composition colonizing SSF biofilms. The efficiency with which selected Oomycete strains belonging to the genus Phytophthora (P. alni, P. cactorum, P. plurivora) were removed from water was determined based on genetic material (DNA of the organisms) found in the SSF filtrate. Specific primers and TaqMan probes (qPCR) appeared to be the most sensitive molecular methods. Moreover, the microbiological analysis of SSF biofilm performed with selective media allowed the growth of copiothrophic and oligothrophic bacteria to be estimated. The influence of fungicide (PCNB) and N-fertilizer on the number of bacteria in each biofilm was also evaluated. The pollution of water with fertilizer (being used for plant irrigation) was demonstrated to reduce the efficiency of filtration more than fungicide addition (the amount of DNA from those investigated pathogens in the water decreased with time). The amount of bacteria in SSF biofilm readily increased after application of N-fertilizer in contrast to fungicide (PCNB) addition.

Opis:
The study evaluated the effect of inoculation with Hebeloma crustuliniforme and application of Biochikol 020 PC to the soil in three doses (single, double and triple) on the growth of Scots pine in the nursery and plantation. Both treatments stimulated the growth of seedlings. The effect of Biochikol was found only in the nursery irrespective of the used doses of the preparation. The effect of mycorrhization on pine growth was stronger compared to the application of Biochikol both in the nursery and plantation.
