【Abstract】 Effects of engineered diazotrophs(Alcaling enes faecalis) on salt tolerance of rice in field and pot were studied. The results indicated that engineered diazotrophs increased SOD activity and photosynthetic rate and decreased MDA content of rice leaves under salt stress. The yield of rice in salinized field was promoted over 17% when inoculated with engineered deazotrophs. The basic theory on improvement of salt tolerance in rice by using engineered diazotrophs is also presented in this paper.更多还原
