Vast areas of Western Siberia (about 40%) are occupied by saline soils. Solonetzic agricultural lands mainly used for growing perennial grasses - phytomeliorants. To increase the yield fodder crops on solonetz lands, specialists Siberian Research Institute Fodder Crops in 80s last century developed phytomeliorative crop rotations. The article considers effect grassing rotations with a mixture b...

In the conditions of northern arable farming, productivity and nutritional value dry mass pure stand Tr. pratense three-component agrophytocenoses with participation meadow clover, as well legume cereal representatives ( Galega orientalis Lam., Medicago varia Mart., Bromus inermis Leys., Phlum L.) were studied. Against background spring fertilizing N45P60K90 two-time mowing, yield biomass grass...

Bromus turcomanicus, a narrow endemic species in central Kopetdagh hitherto known only from the type locality in southern Turkmenistan, is newly recor...

Chromosome morphometry and nuclear DNA content are useful data for cytotaxonomy and to understand the evolutionary history of different taxa. For the genus Bromus Linnaeus, 1753, distinct ploidy levels have been reported, occurring from diploid to duodecaploid species. The geographic distribution of Bromus species has been correlated with chromosome number and ploidy level. In this study, the a...
