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，利于光合提高
The contents of chlorophyll (chl) in tobacco leaves treated with appropriate concentrations of choline chloride (CC) increased slightly, and the reactivity and photosynthetic rate of Hil increased. Leaf Mg2 + -ATPase and Ca2 + -ATPase activity were enhanced. No effect on normal respiratory metabolic activity, but reduced the photorespiration of glycolate oxidase activity, which will help improve photosynthesis
