Abstract

To investigate the effects of melatonin (MT) on kiwifruit seedlings under low temperature (LT) stress, seedlings of Actinidia eriantha were primed with MT solution by root irrigation, relative electrolyte leakage (REL), malonaldehyde (MDA) content, chlorophyll content (ChI), hydrogen peroxide (H2O2) content and antioxidant enzyme activity were measured. The results showed that under LT stress, REL, MDA, H2O2 content, ChI content and POD activity increased apparently in seedling leaves. However, MT application not only effectively reduced REL, H2O2 content and MDA content, but also improved significantly the activity of SOD and CAT in leaves of kiwifruit seedlings under low temperature stress. The results suggested that exogenous MT alleviated the damage by low temperature stress in kiwifruit seedlings and thus improve the ability of plants to tolerance low temperature.
