摘要/Abstract

摘要： 0.1mmol/L的脱落酸、0.1mmol/L的玉米素及玉米素和脱落酸的混合液分别处理连体及离体小麦叶片。结果表明,脱落酸促进叶绿素的降解,降低叶片的光合速率、碳酸酐酶活性、RuBP羧化酸活性以及PSⅠ,PSⅡ的电子传递能力;玉米素则相反;混合液表现了玉米素对脱落酸的拮抗作用,激素对光合参数不同程度的影响,可能是影响植物叶片光合功能衰退的内在原因之一。

Abstract: The attached and detached leaves of the wheat were treated with ABA(0.1 mmol/L),Zeatin(0.1 mmol/L) and their mixture (Zeatin+ABA=0.1 mmol/L+0.2 mmol/L),respectively.The results demonstrated that ABA prompted the degradation of chlorophyll and seduced the rates of photosynthetic oxygen evolution,the activities of RuBPcase and carbonic anhydrase,the capacities of electron transport of PSⅠ and PSⅡ in wheat leaves.The effects of zeatin were contrary to that of the ABA,and their mixture showed an antagonism of zeatin against ABA.The effects of hormones on photosynthetic characteristics in varying degrees could be one of the causes of the decline in photosynthetic function in plant.

Key words: Abscisic acid, Zeatin, Photosynthetic rate, Carbonic anhydrase, RuBPcase
