摘　　要：玉米(Zea mays L.)是世界第三大粮食作物,也是重要的能源、饲料植物.本研究以玉米毛状根再生植株为材料,吉单35自交系为对照,探究了玉米毛状根再生植株叶片在光化学过程中光系统Ⅱ(PSⅡ)的最大光合效率(F_v/F_m)、光系统Ⅱ的潜在活性(Fv/Fo)、光化学淬灭系数(qp)、非光化学淬灭系数(NPQ)等叶绿素荧光特性.结果显示,玉米毛状根再生植株叶片的4种叶绿素荧光特性均优于对照,说明毛状根再生植株具有较高的光能利用效率,能积累更多干物质,从而提高产量.本研究为深入探究玉米毛状根再生植株的光能高效利用机制奠定基础.Maize is the third largest food crop in the world, and is important feed and energy plant. In this study, maize regenerative plants from hairy root cultures were as material ,Jidan 35 inbred lines were as control group, Fv/Fm, Fv/Fo, qp and NPQ of the maized regenerative plants leaf blode in ps II in the photochemical process were analyzed. Results showed that the four chlorophyll fluorescence characteristics of regenerative plant were all superior to the control, indicating that it had an efficiency light utilization and can accumulate more dry substances, consequently increase yield. Our explore the efficient light utilization mechanism of maize regenerative plants from hairy root cultures.
