摘要
该实验研究不同浓度的锌对小麦幼苗叶片光合特性的影响.实验结果表明,小麦幼苗叶片叶绿素含量在在处理浓度为2.0 mg/L时比对照组增加了10.17%,荧光动力学参数NPQ的值在处理浓度为5.0 mg/L时比对照组增加了34.31%,ETR的值在处理浓度为3.0 mg/L时比对照组增加了26.18%,qP和φPSⅡ的值在处理浓度为5.0 mg/L时分别降低24.17%和27.47%.但锌处理对小麦幼苗荧光动力学参数中Fv/Fm和Fv'/Fm'的值的影响不显著.
This experiment studied the chlorophyll content and chlorophyll fluorescence with different Zn cencentration in wheat seedlings. The results indicated that the chlorophyll contents and some of the chlorophyll fluorescence could be changed markedly with the treatment of the different Zn concentrations： the values of the chlorophyll contents, NPQ and ETR could be increased by 10.13%, 34.31% and 26.18% respectively with 2.0 mg/L, 5.0 mg/ L and 3.0 mg/L treatment. The values of qP and φPS Ⅱ , however, were decreased by 24.14% and 27.47% re- spectively. There were no effects on the values of Fv/Fm and Fv＇/Fm＇.
