Measurement of H₂O₂ content, enzymatic activities of POD, SOD, and CAT, and soluble sugar content in WT and transgenic lines under normal, cold, drought, and recovery conditions. 100-day-old banana seedlings were exposed to low temperature at 8°C for 5 days and recovery for 10 days or treated by withholding water for 15 days and recovery for 10 days, then the leaf samples were collected to examine physiological indices. Duncan’s range test was used for significance examination (n = 3; P < .05).
