| 摘 要： | 目的]探究不同山茶品种的抗寒性。方法]采用人工模拟低温处理的方法对3个山茶品种(逸香、克里木、六角大红)的耐寒性进行了测定,分析各生理指标与抗寒性的关系。结果]不同低温胁迫下(0、-5、-10、-15℃),逸香的抗寒性明显高于克里木和六角大红。相关性分析表明,山茶的耐寒性与相对电导率和丙二醛(MDA)含量成反比,与超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性、可溶性蛋白含量成正比。结论]该研究可为低温地区山茶生产、引种以及园林应用提供参考。

Effects of Low Temperature Stress on the Physiological and Bioochemical Indices of Different Camellia Cultivars |
| |
| Abstract: | Objective] To explore the cold resistance of different camellia cultivars.Method] Using artificial low temperature method, the cold resistance of three cultivars of camellia (Camellia sinensis, Camellia crimea, Camellia japonica) was determined.The relationship between phys-iological and biochemical indices and cold resistance of camellia was analyzed.Result] Under low temperature stress(0,-5,-10,-15 ℃), the cold resistance of C.sinensis was significantly higher than that of C.crimea and C.japonica.The correlation analysis showed that the cold har-diness of camellia was inversely proportional to MDA content and relative electrical conductivity, but it was directly proportional to SOD activity , POD activity and soluble protein content.Conclusion] The research can provide references for the production, introduction and gardening appli-cation of camellia in low temperature region. |
