摘要:
利用植物效能分析仪,研究水分胁迫对澳洲坚果叶绿素 a荧光动力学参数的影响 .结果表明,水分胁迫下澳洲坚果叶绿素 a荧光动力学参数中,可变荧光 (Fv)下降,光系统 (PS )原初光能转换效率 (Fv/ Fm)和 PS 的潜在活性 (Fv/ Fo)降低 .Fv,Fv/ Fm 和 Fv/ Fo在水分胁迫各处理的变化趋势为 N>L>M>CK,且不同品种间值的大小也存在一定差异 .随着水分胁迫强度的加剧,Fv,Fv/ Fm 和 Fv/ Fo值也明显变小 .
Abstract:
By applying analyser of plant efficacy, the authors study the effect of water stress on the kinetic parameters of fluorescence in chlorophyll a of Macadamia . As indicate by the results, variable fluorescence yield ( F v) among kinetic parameters of fluorescence in chlorophyll a of Macadamia comes down under water stress; efficiency of primary light energy conversion, which can be shown by the ratio of variable to maximal fluorescence ( F v/ F m), of photosystem Ⅱ reduces; potential activity, which can be shown by the ratio of variable to minimal fluorescence ( F v/ F m), of photosystem Ⅱ reduces; F v, F v/F m and F v/F m change differen tly under different extent of water stress in the order as follows: normal irrigation>insufficient irrigation>excessive irrigation>no irrigation; certain discrepancy exists between the values of different cultivars; the values of F v, F v/F m and F v/F m decrease obviously with the increase of the intensity of water stress.
