  1. *Percentage data were transformed to the Arcsin ()1/2 before the performance of ANOVA Values within the same column followed by different letters are significant different at P ≤ 0.05 by Tukey’s test for the different temperature and photoperiod treatments. The data are the means of three replicates, each with 5 plants.
