Phenotype of GA-treated bamboo seedlings. a: Effects of GA3, PAC or GA3 + PAC on moso bamboo. Two-week-old bamboo seedlings were treated with H2O, GA3 (100 μM), PAC (200 μM) every day for two weeks, and phenotypic characteristics were then recorded. Internode length: the length between second and third leaf. Stem length: from the top node to the first node. Root length: the length of primary root. Leaf width: the width of the leaf at the widest point. First elongated internode: the internode between second and third node. White line represents 3 cm in that pixel. b: Statistical analysis of the effects of GA3, PAC or GA3 + PAC on internode length, leaf width, root length and stem length of moso bamboo. Values were Mean ± SEM from replicates, and the bars represent SEM. Student t test was used to evaluate the difference at the 0.05 probability level. Asterisk indicates a significant difference. “***”: P < 0.001; “****”: P < 0.0001. The number of seedlings is presented in the parentheses on the bars
