Studying the structure of pricopopulations and quality of seed seeds of bushes Ural river loan

Abstract

Abstract The article presents the results of studying the species structure, abundance and quality of seed material of shrubs in the floodplain of the Ural River. The most frequently encountered species was Rosa majalis and Lonisera tatarica (the frequency of occurrence for both species is 63%), which remain viable after more or less prolonged flooding with flood waters and withstand their alluvial sleep. Rhamnus cathartica (53.6%) and Prunus spinosa (51.2%) can also be attributed to the number of commonly seen speciesThe least encountered species were Elaeagnus angustifolia, Euonymus verrucosa, Cotoneaster melanocarpus, Corylus avellana, Crataegus ambigua, which were found in only one type of forest. At the same time, germination, viability and high quality met standard quality indicators. Cerasus fruticosa seeds were characterized by the highest sowing qualities, the least - by Ribes nigrum.
