- Abstract
【Objective】 To study the effects of drought stress on germination of wild Elymus L. materials and evaluate its drought resistance. 【Method】The experimental materials were seven wild germplasms which were collected from different areas of Xinjiang. During the whole germination period, PEG-6000 was used to simulate the drought environment and 6 different concentrations (0, 10%, 15%, 20%, 25% and 30%) were set and indicators of germination, radicle and plumule length of each material under different drought stress were measured.【Result】Low concentration of PEG promoted the germination of some materials, radicle and plumule of P03, P04, P06 and P07 germplasms. When the concentration of PEG reached more than 20%, the germination of all materials was inhibited and the length of radicle and plumule decreased.【Conclusion】The seven materials were sorted according to their drought resistance as follows: P01>P02>P03> P04>P07> P05>P06.
