Mean values in the same column followed by the same letters within variables are not significantly different among six treatments, and the same row followed by the same letters in parentheses between the two cultivars with the same water and ABA or Flu treatment. Letters (a–c) showing least significant difference between treatments and cultivars at the 0.05 level.
