CK control temperature, HT high temperature. Data are the average of three replicates ± standard error (n = 3). The different superscript lower-case letters indicate significance between the temperature treatments for the same cultivar at P < 0.05. Asterisk indicates significance between the two cultivars for same temperature treatment at P < 0.05
