  1. Different small letters with values indicate significant differences from each other (P < 0.05; Tukey’s test).
  2. Treatments: PAS (pre-acclimation stage), CAS1 (cold acclimation stage 1), CAS2 (cold acclimation stage 2), CAS3 (cold acclimation stage 3).
  3. Genotypes: cold tolerant (CT), cold sensitive (CS).
