Abstract This paper studied the effects of different external homone (GA 3 and 6-BA) on the regulation of leaf water and alleviatation of high temperature injury degree of common bean ( Phaseolus vulgaris L.) under high temperature condition. The results showed that,in a short period,the intercellular air spaces increased,leaf temperature became lower and cell membrane injury was alleviated in leaves,however,both external hormone treatment had less effects on leaf diffusion resistance.
