摘要
在人工气候箱中,用不同低温和高温条件胁迫银杏幼苗,测定了叶片离子相对渗透率、超氧化物歧化酶活性、过氧化物酶活性、脯氨酸和丙二醛含量的相关变化关系。研究结果表明:银杏抗热性能较差,但有一定抗寒能力.
Measured the relatively ratio of leaves ions-leakage, SOD, POD, and content changes of proline and malonaldehyde of Ginkgo seedlings with different temperature condition in man-made climate equipment. The results show that: Ginkgo has some chilling-resistance, less hot-resistance capacity.
