The experiment in treating three proce ssed grape species, Roudin gxiang, Baixiexi and Jinyu,with brassinolide (BR)was carried out and the effect s of 0.01mg/L BR were tested by spray ing on leaves and soaking the fruit-spike on the bearing. It showed that BR ca n o utstandingly raise the bearing rate, and increase the weight of single fruit, th e ratio of length/diameter of fruit and the soluble carbohydrates in fruit in di fferent degree. It was obvious that spraying BR 0.01mg/L on the grape leaves would raise the degree of soluble carbohydrates in fruit.
