摘要：
In this study, the wild kiwifruit seedlings were used as the research object to investigate the oxidation resistance of exogenous melatonin on leaves of kiwifruit seedlings under copper stress, adopting the root irrigation method. The results showed that exogenous melatonin effectively increased the content of proline in leaves of kiwifruit seedlings under copper stress, enhanced the osmotic adjustment ability of plant cells, increased the antioxidant substances and improve the antioxidant capacity, reduced the toxicity of copper stress on kiwifruit and promote the tolerance of plants. The results indicated that exogenous melatonin could availably alleviate the toxicity of copper stress on kiwifruit seedlings and increase the tolerance of plants to heavy metal stress.
