Bu: bud formation, F: flower formation, FF: full flowering, and Se: seed formation. nd: not detected. Data are reported as means ± SD (n = 3) and compared to control (C). ANOVA is followed by Duncan multiple range test (P < 0.05). Values in the same column with different superscripts (a–d) are significantly different at P < 0.05.
