甲壳素对蔬菜抗逆性的影响

摘要

本文研究了甲壳素处理对樱桃番茄、番茄和小白菜抗逆性的影响。结果显示，甲壳素处理可提高樱桃番茄的番茄脯氨酸含量，降低其丙二醛（MDA）含量和电解质的渗透率，其中樱桃番茄脯氨酸增加量达到显著性水平，从而增强了它们的抗高温能力。另外，甲壳素处理可以显著提高小白菜叶片中脯氨酸的含量，降低丙二醛的含量，从而提高其抗寒能力。%In this paper, effect of chitin on vegetable resistance index was studied. The result showed that chitin increased the content of proline in tomato leaves, and decreased the content of MDA and electrolytic leakage. Proline content in tomato was significantly increased with chitin application. Chitin also increased proline content in Chinese cabbage leaves, and decreased the MDA content, improving its cold-resistance.
