Cytokinin treatment is capable to change the FvDB identity. a The IAA, zeatin and ABA level were detected in FvDB, FvNDB and FpNDB by HPLC. The data were obtained from three biological replicates. P-values were determined by two-tailed Student’s t-test (*p < 0.05, **p < 0.01, ****p < 0.0001). b Statistical analysis of the bud outgrowth frequency in FvDB upon NPA treatment (100 μM for 14 days) or decapitation. The data were obtained from three biological replicates, (N = 20, 19, 20 for control, NPA, decapitation, respectively). c Statistical analysis of the bud outgrowth and turnover frequency in FvDB upon 6-BA and IAA co-treatment for 16 days (concentrations were indicated in the chart). The data were obtained from three biological replicates (From left to right, N = 20, 20, 20, 20, 21, 18, 15, 15, respectively). d NPA or decapitation promotes bud outgrowth of FvDB. Red box highlighted the new runner that was growing from the dormant-bud, and the two-times enlarged picture was shown. e Cytokinin treatment is able to switch the FvDB to FvNDB like identity. Red box highlights the turn-over bud which was shifted from dormant to non-dormant identity, and the two-times enlarged picture was shown
