Species belonging to different sections of the genus Polygonum L. were studied micro-morphologically. For this purpose, digital images were obtained from all species and lower taxa belonging to sections Persicaria, Bistorta, Tiniaria and Pleuropterus. Since section Polygonum is much diverse, pollens of three representative species Polygonum luzuloides, P. olivascens and P. setosum were photogra...

The main gradient in vascular plant, bryophyte and lichen species composition in alpine areas, structured by the topographic gradient from wind-exposed ridges to snowbeds, has been extensively studied. Tolerance to environmental stress, resulting from wind abrasion and desiccation towards windswept ridges or reduced growing season due to prolonged snow cover towards snowbeds, is an important ec...

We investigated changes in the root-associated fungal communities associated with the ectomycorrhizal herb Bistorta vivipara along a primary succession gradient using 454 amplicon sequencing. Our main objective was to assess the degree of variation in fungal richness and community composition as vegetation cover increases along the chronosequence. Sixty root systems of B. vivipara were sampled ...

Weed management is essential for sustainable crop production in all cropping systems. The use of herbicides causing the problems herbicide resistant weeds and environmental pollution. Plant-released phytotoxins have ability to promote or inhibit germination seedling growth surrounding crops weeds. Therefore, it imperative identify plant species having herbicidal potential as more safe weed appr...
