摘要
经喷施合适浓度的氯化胆碱（ＣＣ）的烟草叶内叶绿素（ｃｈｌ）含量略有增加，希尔（Ｈｉｌ）反应活力和光合速率提高。叶内Ｍｇ２＋－ＡＴＰａｓｅ和Ｃａ２＋－ＡＴＰａｓｅ活性均有所增强。对正常的呼吸代谢活力无影响，但降低了光呼吸中的乙醇酸氧化酶活性。
After the tobacco (Nicotiana tabacum L.) was sprayed with suitable concentrations (200～300 mg·L-1) of choline chloride (CC) in different developmental stages, the content of chlorophyll in leaf was increased slightly, the Hill reaction activity and photosynthetic rate were increased, and the activities of Ca2+-ATPase and Mg2+-ATPase were promoted; the activity of key enzyme glycolate oxidase in photorespiration was decreased,but the activity of basic respiration was not changed.
