Abstract

Drought is one of the most important factors limiting plant GROWTH around the world and it is the most common environmental stress. The lack of water in the pastures causes GROWTH reduction and the establishment of varieties in this areas. Due attention to ecological importance of pastures and effects of three level of DROUGHT STRESS FC, FC50% on, for conserve the soil, in present research, the GROWTH of varieties: Secale montanum, Bromus tomentellus, Agropyron desertorom from grasses and Onobrychis sativa, Medicago sativa from legoms was considered. From each species two genotypes were selected. Factorial experiment based on completely randomized design in 4 replications was conducted in greenhouse conditions. Root length, shoot length, seedling length, root to shoot ratio, root, shoot and seedling dry weight as well as dry weight to fresh ratio, the amount of CHLOROPHYLL a, b, and total were assessed. Under DROUGHT STRESS increased root length and the amount of CHLOROPHYLL increased and the most other traits, especially at FC 50% reduction was significant. Secale cermond ecotype seedlings had the most GROWTH and Agropyron cristatum ecotype seedlings had the lowest GROWTH rate and CHLOROPHYLL. In examining the interaction of drought and species the highest total CHLOROPHYLL and b CHLOROPHYLL were observed in Medicago 44 that were treated with FC 50%.From ten under studied ecotypes under DROUGHT STRESS, Secale cermond had the better GROWTH.
