| 摘 要： | 为探明酸雨对春小麦光合特性及产量的影响,用pH为1.5,2.5,3.5,4.5和5.6的模拟酸雨在春小麦孕穗期对其进行喷淋,然后测定不同pH模拟酸雨处理后春小麦叶片的光合参数及产量。研究结果表明,1)酸雨对春小麦叶片光合特性以及产量的影响随酸雨的氢离子浓度增大而愈显著。2)酸雨pH与净光合速率、气孔导度、蒸腾速率、水分利用效率、叶绿素相对含量以及春小麦产量均呈极显著正相关,与胞间CO2浓度呈极显著负相关。

| Abstract: | To investigate the effects of acid rain on photosynthetic characteristics of spring wheat at the booting stage,plants were sprayed with simulated acid rain at pH levels of 1.5,2.5,3.5,4.5,or 5.6.Yield and photosynthetic parameters of the spring wheat leaves were monitored.1) The effects of simulated acid rain on photosynthetic characteristics of spring wheat leaves increased as the hydrogen ion concentration increased.2) The pH values of simulated acid rain were significantly positively correlated with net ... |
