Note:
Values are means ± standard errors (n = 4). Different alphabetical letters as superscripted within the same column indicate significant differences among various treatments according to a least significant difference test (LSD) at P < 0.05. WL, water-sprayed waterlogged-stressed plants; CK+WL, cytokinin (CK)-sprayed (50 mg L−1) waterlogged-stressed plants; GA3+WL, gibberellic acid (GA)-sprayed (50 mg L−1) waterlogged-stressed plants; DW, dry weight.
