为探究模拟酸雨对茶树叶片光合生理的影响,使用盆栽湘妃翠茶树幼苗作为实验材料,对其进行模拟酸雨处理,酸雨浓度梯度为pH 2.5、pH 3.5、pH 4.5,自来水作为对照,检测模拟酸雨对茶树幼苗叶片光合色素含量以及光合作用CO_2响应曲线的影响。结果表明:pH 4.5与pH 3.5模拟酸雨处理对茶树幼苗叶片叶绿素a、叶绿素b以及类胡萝卜素含量无显著性影响,pH 2.5模拟酸雨处理使其含量显著降低;光合作用CO_2响应曲线使用直角双曲线模型进行拟合,pH 2.5模拟酸雨组初始羧化效率(carboxylation efficiency,CE)、光合能力(A_(max))显著低于对照组,pH 4.5处理组光合能力(A_(max))显著升高,其他处理组羧化效率(CE)、光...

To explore the effects of simulated acid rain on photosynthetic physiology of tea leaves,using potted tea seedlings,potted Xiangfeicui tea seedlings were used as experimental materials to simulate acid rain treatment.The concentration of acid rain was pH 2.5,pH 3.5 and pH 4.5,and tap water was used as a control.The effects of simulated acid rain on the content of photosynthetic pigment and photosynthesis Ci curves of tea seedlings were detected.The results showed that pH 4.5 and pH 3.5 simulated acid rain had no significant effect on chlorophyll a,chlorophyll b and carotenoid content in leaves...
