| 摘 要： | 本文研究了冷驯化和ABA对茶树抗寒力及其体内脯氨酸含量的影响,结果表明：通过冷驯化或者ABA处理,茶树经历了驯化再到脱驯化的过程,相应地茶树的抗寒力也发生了很大的变化,由驯化前的几乎为0逐渐增大,而随着脱驯化的进行又迅速恢复到驯化前的水平。低温驯化的临界温度为7℃左右,脱驯化的临界温度为9℃左右。人工低温驯化和ABA处理,茶树抗寒力的提高幅度没有自然冷驯化下的大。对三种处理下茶树体内脯氨酸含量的变化的研究发现,冷驯化中茶树体内脯氨酸含量变化是对外界条件变化的一种综合反应,很难说明单一的脯氨酸含量与抗寒力之间的因果关系。

| Abstract: | Effect of cold acclimation and ABA on cold hardiness resistance, contents of proline in tea plants was studied. The results showed that through cold acclimation and ABA treatment, the cold hardiness of tea plants was changed greatly during the process of acclimation to deacclimation, showing a trend from low to high then to low again. And ascertain 7℃and 9℃are the crucial temperature to finish acclimation or start declimation respectively. On the other hand, it can be concluded that the rising degree of cold hardiness resistance was lower during artificial or ABA treatment than that of natural cold acclimation. At the same time, changes of Proline content weren’t regular, the relationship between proline content and cold hardiness resistance was insignificant. It implied that changes of proline content during cold acclimation were an integrative response in tea plant. |
