Abstract:
Taking Ligustrum quihoui Carr.as test materials,and using the spray method to investigate the effects of brassinolide on spring and summer shoot growth of L.quihoui.with the effective component content of 0.005-0.025 mg?kg-1,so as to provide a theoretical basis and technical guidance for the rational use of brassinolide on L.quihoui.The results showed that,with the increase of active components of brassinolide,the increment of shoots length and coarseness,length,width,thickness and weight of leaves increased,but the abnormal rate of leaves also increased,significantly.Compared with blank control,when the effective component content of 0.010-0.020 mg?kg-1 were applied,the increment of shoots length and coarseness,length,width,thickness and weight of leaves all increased,and the abnormal rate of leaves has no significant difference.Correlation analysis showed,as for the spring shoots,different brassinolide concentrations with the increment of shoots length,thickness and abnormal rate of leaves were highly significant positive correlation,the correlation coefficient was above 0.83.The different brassinolide concentrations with the increment of shoots coarseness,length,width and weight of leaves were significant positive correlation,the correlation coefficient was above 0.51.As for the summer shoots,in addition to the increment of shoots coarseness had no significant correlation between concentrations,other correlation with spring shoots were the same.With the increase of active components of brassinolide could effectively promote the growth of branches and leaves,but increase the abnormal rate of leaves.Comprehensive analysis,the L.quihoui could be used the effective component content of 0.010-0.020 mg?kg-1 by spray processing to treatment in the growth stage of spring and summer shoots,it increased the increment of shoots length and coarseness,length,width,thickness and weight of leaves,and the abnormal rate of leaves was low.
