Effect of Temperature on Seed Germination of Some Steppe Species

摘要

ABSTRACT Climate change is becoming more restrictive for growth and development of plants particularly in semiarid and arid areas. This natural stress (drought) has changed the ecosystem stability and is largely the cause of desertification and land degradation as a consequence of vegetation. If the species is auto-ecologically suited to the site, its growth and development still require adaptation to local conditions of intra-and interspecific competition. In particular, it has been shown that.
