Seeds harbor a complex fungal community, of which some members may be pathogenic. For this reason, seeds are often treated with fungicides before sowing. Plant protection is constantly looking for environmentally friendly technological solutions and nanotechnology can provide a solution that is a green and environmentally friendly alternative to fu...

Silver birch Betula pendula is a pioneer tree species that often naturally regenerates on post−agricultural land. The succession of ectomycorrhizal fungi depends on many factors including local environmental conditions and in particular soil conditions. Therefore, the objective of this study was to analyse the mycorrhizal fungal communities in four...

Wood technology is constantly looking for environmentally friendly technological solutions. It seems that nanotechnology can provide green and environmentally friendly alternatives for wood protection. In this study, the antifungal activity of silver and copper nanoparticles against the white rot fungus Fomes fomentarius was investigated under in v...

In European forests, the Scots pine (Pinus sylvestris L.) most often regenerates on clearcuts, following mechanical site preparation. Both of these silvicultural treatments (the removal of trees and preparation) have an impact on soil properties, and on the mycorrhizal fungi associated with the roots of seedlings. We therefore compared assemblages...

Ectomycorrhizal fungal assemblages in 35−years−old Scots pine stand growing on former agricultural land. Sylwan 165 (1): 50−60. DOI: https://doi.org/10.26202/sylwan.2020112. Ectomycorrhiza is one of the key factors influencing the success of afforestation of post−agricultural land. Currently, the assemblage of mycorrhizal fungi occurring in young f...

Modern forestry in the European Union and in Poland is in constant search of environment-friendly technological solutions. These also relate to nursery production , in which attempts are made to apply non-chemical plant-protection products. The objective of this study was to assess the effects of salicylic acid, oxalic acid and chitosan (applied in...

Metal nanoparticles are gaining ever-wider application in agriculture and forestry, as alternatives to chemical agents used as fertilisers, growth stimulators and pesticides, establishing a need for eco-toxicological risk assessment of these agents. We tested the effects of foliar-applied silver nanoparticles (AgNPs) on chlorophyll a fluorescence a...

Recent research points to the possibility of nanoparticles being used as fertilis-ers, growth stimulators, and promoters of plant resistance or pesticides. In this study, we sought to determine the influence of nanoparticles of silver and copper (AgNPs and CuNPs) on growth parameters and spontaneous mycorrhizal colonisation of roots in 2-year-old c...

Metal nanoparticles (NPs) are finding ever-wider applications in plant production (agricultural and forestry-related) as fertilisers, pesticides and growth stimulators. This makes it essential to examine their impact on a variety of plants, including trees. In the study detailed here, we investigated the effects of nanoparticles of silver and coppe...

While some tree species can regenerate naturally without mechanical site preparation (MSP), Scots pine has been shown to benefit from this process. We compared three methods: using a double-mouldboard forest plough (FP), an active single-disc plough (AP), and a forest mill (FM), as well as a no-MSP control, in terms of growth, survival and density...

As research indicates a role for metal nanoparticles as fungicides, the work described here addresses the influence of copper nanoparticles (CuNPs) and silver nanoparticles (AgNPs) on the growth in vitro of pathogens causing damping-off as well as wood-decay fungi; i.e., Rhizoctonia solani (2 strains), Fusarium oxysporum, F. redolens and Phytophtho...

Scots pine stands in central Poland are now seen to be experiencing dynamic development of lower layers formed by oaks. The under-canopy natural renewal taking place in this way is sometimes characterised by good silvicultural quality, and could therefore be taken advantage of in the process of stand conversion. The study assess the quality of exis...

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 most cases, mechanical site preparation (MSP) is a precondition if high-quality (natural or artificial) regeneration of forests is to be achieved. However, the measures involved here may differ in terms of the level of intervention of the soil environment, at both the surface and deeper down. The choice of MSP methods should be based on climatic...

Successful tree regeneration is a key process in ensuring forest sustainability and one of the most crucial investments made in silviculture. This study compared the effects of three reforestation methods (planting, direct seeding, and natural regeneration) and three mechanical site preparation methods (double mould-board forest plough (FP); active...

The aim of this study was to determine the mycorrhizal status of nursery seedlings of the wild service tree (Sorbus torminalis), which belongs to the Rosaceae family. Its mycorrhizal associations are still fragmentarily known, and data from the few existing studies indicate that it forms ectomycorrhizal symbiosis (ECM). We analyzed the degree of my...

Different methods of logging slash management (LSM) and methods of soil preparation (MSP) can create different conditions for the growth of forest trees. This occurs through variation in soil aeration, tree nutrition or microbial conditions. These factors are modified by climate, soil fertility, treats from insects or fungal pathogens and renewed s...

Chitosan has become a promising biological agent for disease control and plant growth promotion. The objective of this study was to assess the effects of chitosan, applied as an active ingredient of Beta-chikol (Poli-Farm, Łowicz, Poland), to control damping-off and Lophodermium needle cast on Scots pine seedlings growing in field conditions. Beta-...

Mechanical site preparation (MSP) is commonly used to enable forest regeneration of clear-cuts. Less intense methods may be more suitable from an environmental point of view, but such a method can result in the lack of natural regeneration. We compare the influence of three MSP methods on natural regeneration of Scots pine. The methods differ in th...

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 th...
