Abstract :
In order to further understand the stress tolerance of T1 generation of transgenic Perennial Ryegrass (Lolium perenne) with DREB1A gene, the research is focused on the analysis of the physiological properties of transgenic plants after saline and drought treatment at germination stage, with the control group of water treatment. Compared with the control group, stress treatment had a significant impact on all materials. The result of relative germination potential, relative germination rate, seedling height, chlorophyll content, wilting degree and survival range showed that, all materials with DREB1A gene showed a higher tolerance than the non-transgenic ones and the difference was significant. The contents of relative conductivity and relative water content showed the increased tolerance of transgenic plants, but the difference between transgenic plants and CK was not significant. This suggested that transgenic Perennial Ryegrass was stress-tolerant and could be extended in drought and salinity soil to improve drought and salinity land.
