| 摘 要： | 以同源四倍体品种天星、烟嘎1号和对应的二倍体品种富士、烟嘎1号为试材,研究了苹果四倍体品种叶绿素荧光参数的日变化规律.结果表明,初始荧光(Fo)、最大荧光(Fm)、PS Ⅱ原初光能转化效率(Fv/Fm)、PSⅡ的潜在光化学效率(Fv/Fo)、以吸收光能为基础的光合性能指数(PI)均存在明显的日变化.其中Fm、Fv/Fm...

| Abstract: | The diurnal variations of chlorophyll fluorescence parameters of apple leaves were studied using autotetraploid varieties Tensei and 4x Yan 1 Gala as well as the diploid cultivars Fuji and Yan 1 Gala as materials.The results indicated that the changes of Fo,Fm,Fv /Fm,Fv/Fo and PI in a day were significant.Fm,Fv /Fm and Fv/Fo showed similar changes,and all the values first declined and then rose.The lowest values appeared at noon,however,tetraploid varieties dropped more greatly than diploid varieties.Fm,Fv/... |
