摘 要 ：

以不同浓度NaHSO₃ 对油茶进行叶面喷施。结果表明:150～250mg·L^-1 NaHSO₃ 可以明显抑制叶片的光呼吸,提高光合速率,增加经济产量。NaHSO₃ 对光呼吸的抑制与乙醇酸氧化酶活性下降及乙醇酸含量增加表现一致。同时研究表明,NaHSO₃ 对细胞内超氧物歧化酶(SOD)活性和过氧化氢酶(CAT)活性以及膜脂过氧化产物丙二醛(MDA)含量均无明显影响,说明不会对细胞造成伤害。

Abstract:

Spraying the leaves surfaces of Camellia oleifera with different concentration sodium bisulfite.The results indicated that 150～250 mg·L^-1 NaHSO₃ could inhibit photorespiration, promote net photosynthesis and increase economic yield.This coincides at same time with a series of changes of glycolate oxygenase activity and glycolate content related to photorespiration.NaHSO₃ on SOD activity and CAT activity and MDA content of Camellia oleifera leaves is no significant differences than the control.NaHSO₃ will not injure a cell of Camellia oleifera leaves.
