Note: Values represent the average surface area between the full flower and the full boll stages. Comparing water treatments within a cultivar, values within a column followed by different letters are significantly different at the 0.05 probability level. Values are means ± SD of three replicates. Abbreviations: CK: conventional irrigation; T1: slight deficit irrigation; T2: moderate deficit irrigation.
