The length of axillary buds in different time periods and different nodes was taken as the index for statistical analysis. *, comparison of axillary bud length between different time periods and 12d before yellow ripe stage, ^*p < 0.05, ^**p < 0.01,^***p < 0.001. #, comparison of axillary bud length between different nodes and the top 2nd, ^#p < 0.05, ^##p < 0.01, ^###p < 0.001. All values were shown as the means ± standard error of the mean of three replicates
