Abstract:: Taking rose cultivar‘Chinese red’as test material，the flowers open at different stages as well as branches in different parts of rooting situation were studied，and the cuttings endogenous hormones gibberellic acid (GA) content，indole-3-acetic acid (IAA) content were determined.The results showed that the survival rate of cuttings of different treatments existed large differences,the survival rate of upper and middle branches in early and middle period of flower could reach more than 60%.Endogenous hormones GA，IAA contents with the performance of the law was open flowers and branches from top to down progress decreasing trend performance，which was consistent with the results of cutting survival rate，the endogenous hormone GA and IAA content was higher，cutting survival rate was higher.Based on the above results，in the actual production，the flowers open before the middle of the mid-branches could be used as cuttings.
