Abstract:
Taking the excellent variety of melon ‘Yangguomimi’ as the experimental material，the seedlings were subjected to flooding stress treatment when they reached three leaves and one heart stage.After 3 days of flooding，different concentrations of 2，4-dichlorophenoxypropionic acid (EBR) (0，0.1，0.2，0.4，0.6，0.8 mg·L-1) were sprayed.The phenotypic and physiological indicators of the melon seedlings were measured and analyzed to study the effect of EBR on the growth of melon seedlings under flooding stress，in order to provide reference for solving the problems such as flooding stress and flooding damage encountered in melon production.The results showed that under flooding stress，the phenotypic traits and physiological indicators of the melon seedlings were significantly affected.The EBR treatment at 0.4 mg·L-1 significantly increased the root length and dry weight of the seedlings.It also led to a significant increase in the activities of peroxidase (POD) and superoxide dismutase (SOD)，as well as an increase in soluble protein content，while the levels of malondialdehyde (MDA) and proline significantly decreased.The comprehensive analysis indicated that the 0.4 mg·L-1 EBR treatment could more effectively alleviate the inhibitory effect of flooding stress on the growth of melon seedlings.
