Abstract

In order to further understand the influence of exogenous GA on drought tolerance of transgenic Perennial Ryegrass (Lolium perenne) with BADH-CMO Gene, the research is focused on the analysis of the physiological properties of transgenic plants after drought and restoration treatment. The result of chlorophyll content, relative conductivity, relative water contend water content and sugar content showed that, drought tolerance of all materials was decreased by exogenous GA and the difference between plants with BADH-CMO gene and non-transgenic ones was significant. It suggested that exogenous GA had influence on stress tolerance of transgenic plants. The further study regarding on the mechanism of this phenomenon is wanted.
