  1. The temperature was set at 15 °C for cold treatment and 27 °C for control. After 4 days of treatment, the temperature was adjusted to 27 °C for 3 days before harvesting
  2. ns non-significant
  3. #Different letters represent the significant difference with LSD tests among cultivars or treatments (p < 0.05)
  4. $G × T: effect of genotype and temperature interaction; *p < 0.05; **p < 0.01
