以品系９３一１１４的橡胶叶片为材料，应用影响膜脂稳定因素为指标，检测、研究和比较离体受冷（０℃）叶片在不同相对湿度条件下的效应，以及经抗坏血酸（Ｖｃ）预处理叶片，对不同相对湿度的敏感性。结果表明，不饱和相对湿度条件下受冷叶片代谢发生急剧变化，且变化幅度大，而饱和相对湿度条件下受冷叶片，代谢变化较为平稳，且变化幅度小；与对照相比，经Ｖｃ预处理叶片，在相同低温不同相对湿度条件下，都有不同程度缓解冷害的效应，尤其在不饱和相对湿度条件下，Ｖｃ预处理叶片抗冷效应更佳。
Using the rubber leaves of lines 93-114 as materials, the effects of membrane lipid stabilizing factors were examined and compared. The effects of the leaves (0 ℃) under different relative humidity conditions and the effect of ascorbic acid (Vc) pretreatment Treatment of leaves, the sensitivity of different relative humidity. The results showed that under the condition of unsaturated relative humidity, the metabolism of cold leaves changed sharply, and the variation range was large. Under the condition of saturated relative humidity, the changes of metabolism were stable and the variation range was small. Compared with the control, Under the same relative humidity at the same low temperature, the treatment leaves had different degrees of chilling injury mitigation effects, especially under the conditions of unsaturated relative humidity, Vc pretreatment leaf cold-resistant effect is better.
