Abstract. Scientific novelty and practical significance. The increasing rates of soil degradation processes in the southern regions Russia make it urgent to increase productivity agricultural land, stabilize ecosystems restore potentially valuable forage vegetation. Phytomeliorative reconstruction low-productive lands is great importance for ensuring sustainable development region national food...

converting the native rangelands to simplified agronomic communities causessome changes in soil carbon, nitrogen and phosphorus. establishing of perennial plantcommunities on formerly cultivated rangelands is expected to stabilize soil properties andincrease the amount of c, n, p stored in rangeland soils, but there is little information on whatplant communities are the most effective for impro...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

Lophopyrum elongatum, a close relative of wheat, provides a source of novel genes for wheat improvement. Molecular markers were developed to monitor the introgression of L. elongatum chromosome segments into hexaploid wheat. Existing simple sequence repeats (SSRs) derived from genomic libraries were initially screened for detecting L. elongatum loci in wheat, but only 6 of the 163 markers teste...
