| 摘 要： | 研究了水分胁迫对4种草坪草光合色素及叶绿素荧光的影响。结果表明,水分胁迫前中期,草坪草的光合色素Chla,Chlb,Car变化不大;胁迫后期,除盆景2000(Bonsai2000)上升外,其他3个品种(Award,Starlet,Accent)均下降,说明草坪草具有一定的抗旱适应能力。叶绿素荧光动力学参数Fo,Fm,Fv,Fv/Fm,Fv/Fo的变化趋势不是单一的上升或下降,不同草坪草,其变化过程和变化幅度也不一样。相关性分析表明,草坪草叶片Car和Chla的含量变化对荧光具有很大的影响。

| Abstract: | Effects of water stress on photosynthetic pigments and chlorophyll fluorescence in four turf grasses(Award,Starlet,Accent and Bonsai2000) were studied.The contents of Chla,Chlb and Car of the 4 grasses changed little at the beginning while decreased except for Bonsai2000 at last,which showed that turf grasses tested had a high adaptability to water stress.The chlorophyll fluorescence induction kinetic parameters(Fo,Fm,Fv,and Fv/Fm) changed differently in direction or degree.The correlation analysis indicated the content of Car and chl a deeply influenced the chlorophyll fluorescence. |
