摘要
Abstract
In order to find out the effects of the agent"Daoqing"on grain yield and its components of rice under heat stress, an ex-periment was conducted by using japonica hybrid rice Changyou 1 as material. The heat stress treatment was applied at the flowering stage, and meanwhile the agent was sprayed with different concentrations. The results showed that, heat stress significantly decreased the seed setting rate, grain weight and grain yield of rice. The agent"Daoqing" significantly increased the seed setting rate, grain weight and grain yield whether under normal or heat stress condition. The increased grain yield was mainly due to the decreased pani-cle temperature, increased activities of antioxidant enzymes, the decreased reactive oxygen species and peroxides. Moreover, the fertil-ity and germination of pollen was increased, slip of the anther was enhanced, and finally resulted in the reduced damage of heat stress to rice production.关键词
