CK, normal watering conditions only; CK + 6-BA, 0.5 mM of 6-BA plus normal watering conditions; W, waterlogged; W + 6-BA, addition of 0.5 mM of 6-BA plus waterlogging stress conditions. Data represent means ± SD of three replicates. For each variable, means with different lowercase letters represent significant differences (P < 0.05).
