摘要:

为了解海岛植物普陀樟在低温胁迫下的生理反应,以普陀樟引种实生苗的叶片为实验材料,于冬季对其进行不同低温梯度的处理,测定了叶片相对电导率、丙二醛含量的变化和过氧化氢酶活性的变化。结果表明,随着温度的降低,普陀樟叶片相对电导率基本处于上升趋势;丙二醛含量也随着温度的降低而增加;过氧化氢酶活性随着温度的降低呈现 “M”型的变化趋势。

关键词: 普陀樟, 抗寒, 相对电导率, 丙二醛, 过氧化氢酶

Abstract:

In order to study physiological responses to the island plant  Cinnamomum japonicum under low temperature stress, the relative electric conductivity, the content of MDA and the activity of CAT were determined under different low temperature treatments for the leaves of Cjaponicum in winter. The results showed that the relative electric conductivity increased, MDA content also increased, CAT showed “M”type changes trend with decreasing temperature.

Key words: Cinnamomum japonicum, Cold-resistance, Relative electric conductivity, MDA, CAT
