a
Mean values ± se. The numbers in the parentheses indicate the sample size. The letters indicate ANOVA Tukey multiple comparison test groupings. Mean values with the same letter in the group are not significantly different (α = 0.05). ND, not determined.
b
The plus sign indicates elongated petioles and premature shoot meristem activation in the dark.
