| Abstract/Contents: | "In order to investigate the drought resistance of 5 perennial graminoid grasses during the germination period, polyethylene glycol (PEG-6000) was used to simulate drought stress. A series of PEG-6000 concentrations,0, -0.05, -0.15, -0.30, -0.49 MPa, were used as osmotic media. The perennial graminoid studied were Elymus sibiricus cv. Tongde, Elymus breviaristus cv. Tongde, Poa crymophila cv. Qinghai, Poa pratensis cv Qinghai and Festuca sinensis cv Qinghai. The germination rate, germination potential, germination index and shoot length, root length and dry weight of seedlings were used as indicators. The results showed that the seed germination rate, germination potential, germination index, shoot length and dry weight of the 5 grasses reduced with the decease of osmotic potential, but the response of different indicators of each grass was inconsistent. High osmotic potential media did not affect the germination, but promoted the growth of seedling roots of Poa crymophila cv. Qinghai and Festuca sinensis cv. Qinghai, and inhibited the roots of the other three grass seedlings. The Membership Function showed that the overall drought resistance of the five grasses during the germination period was ranked as: Elymus sibiricus cv.Tongde > iPoa pratensis cv. Qinghai > Elymus breviaristus cv. Tongde > Poa crymophila cv. Qinghai>iFestuca sinensis cv. Qinghai." |
