Abstract
The study cultured the seedlings of '52-7',a transgenic rice line with transformed BADH gene and its BADH——recipient parents,'Zhonghua 8','Kaixi 7',a dryland variety,and 'Baizhenzhu',a upland rice variety,in the specialized nutrient solutions whose NaCl contents were separately set at 0,5 and 7 g·L~(-1) to examine the salt resistance and its mechanism of '52-7' with the parents as the controls.It showed that under normal circumstances the seedlings of the transgenic rice line had stronger vigor of growth and roots,higher soluble sugar and chlorophyll contents,higher SOD and POD activities than the seedlings of the controls.Under the salt stresses the rice seedlings grew slowly,reduced their root/shoot ratios and increased the vigor of their roots;they increased their membrane permeability,MDA content and SOD and POD activities;they increased their proline and soluble sugar contents and decreased their chlorophyll content and intensified their protein breakdown;as the salt contents increased all these parameters increased differently.Under the salt stresses,the seedlings of the transgenic rice line showed high growth rate,high root-shoot ratio,low electrolyte-exudation rate,low MDA content and weak protein and chlorophyll breakdowns thus having strong salt resistance compared with the seedlings of the controls.Under the stresses the seedlings of the transgenic rice line had much higher proline and soluble sugar contents,much higher SOD and POD activities than those of the controls so that they have strong salt resistance.
