Abstract:

Tibet wild Elymus sibiricus seeds were used as the material, and the water and temperature environment of Elymus sibiricus seed germination was simulated by the interaction of different temperatures (10, 15, 20, 25℃) and different concentrations (0, 5%, 10%, 15%, 20%, 25%) of PEG-6000 to study the seed germination characteristics of wild Elymus sibiricus under different hydrothermal conditions. The results showed that different water and temperature conditions had a significant effect on the germination of Elymus sibiricus (P<0.01); The germination rate, germination potential, germination index and vigor index of Elymus sibiricus were increased with the increase of temperature, with the best response under 25℃; When PEG concentration was 5%, the seed germination rate was higher under 15℃ and 20℃than that under control. When PEG-6000 concentration was 15%, seed germination rate, germination potential, germination index and vigor index were significantly inhibited (P<0.05) and the higher the temperature, the more significant the inhibitory effect. The best germination rate of the wild Elymus sibiricus seeds was at temperature of 25℃ and the concentration of PEG solution was 0-5%. The response of seed germination to moisture depends on the temperature changes, lower temperature inhibited seed germination.

Key words: Elymus sibiricus, Temperature, PEG-6000, Germination, Tibet
