| 摘 要： | 测定了北疆6个不同棉花品种田间叶片的净光合作用、荧光参数的变化，结果表明：晴天棉花叶片的光化学效率Fv/Fm随着光照强度上升而下降，到14：00左右降到最低值，之后又随光照强度的减弱逐渐回升；光化学猝灭系数qN则于此相反。棉叶在晴天易发生光抑制，可能会引发反映中心的降解等破坏反应。产量较高的新陆早8号和新陆早10号的Fv/Fm和qP的值均高，且正午过后Fv/Fm恢复较快，具有较高的PSⅡ活性和光能转化效率，证明光合器官的光能吸收、传递和转化效率是作物高产的生理生化基础。

| Abstract: | This research determined chlorophyll fluorescent light parameter of cotton leaf development period in main cotton breed in North Xinjiang.The light intensity increases Fv/Fm of the cotton leaf descend in sunny days,at 14:00 Fv/Fm descend minimum.Soon afterwards,with the light intensity descended Fv/Fm will increase.But qN is contrary.Cotton leaf is easy to occur light inhibition and will evoke emotion destructive reaction in the middle of reflection.The PSII Fv/Fm and qP of Xinluzao 8 hao (XLZ-8),XLZ-10 are higher than those of XLZ-4,XLZ-1,XLZ-7.But the qN of the former is lower than the later.It indicates the former possesses higher absorbing and transforming capability of light. |
