- 摘要:
- 以月季品种‘中国红’为试材，研究了插穗在花朵不同开放时期及枝条不同部位扦插生根情况，并对插穗内源激素赤霉素(GA）、吲哚-3-乙酸（IAA）含量进行了测定。结果表明：不同处理间扦插成活率存在较大差异，花朵开放前期与中期的枝条上部和中部扦插成活率能够达到60%以上。内源激素GA、IAA含量均表现为随着花朵开放进度及枝条由上而下呈递减趋势，这与扦插成活率结果一致，内源激素GA、IAA的含量越高，扦插成活率越好。综合以上结果，在实际生产中，可以利用花朵开放前中期的上中部枝条作为插穗。
- 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.
