摘要：

以北方粳型超级稻代表品种沈农265和沈农606为试材，秋光和辽粳294为对照，采用盆栽试验，在不同生育时期测定根系伤流速度、根系吸收面积、单株根系氧化力和叶片叶绿素含量、净光合速率、蒸腾速率和气孔导度。结果表明，沈农265和沈农606在整个生育期内根系吸收面积、单株根系氧化力和伤流速度都显著地高于对照品种，特别是在生育后期，根系衰老缓慢，生理活性强。在灌浆结实期，两个品种的叶绿素含量和光合速率与对照品种差异显著，光合特性下降速度明显慢于对照品种。说明超级粳稻沈农265和沈农606具有明显的根系生理优势和叶片光合优势，灌浆结实期根系生理活性与叶片叶绿素含量呈显著正相关。

Abstract:

Two typical japonica super rice cultivar Shennong 265 and Shennong 606 were used as experimental materials and Akihikari and Liaojing 294 as control cultivation.Root physiological activity and leaf photosynthetic capability of Northern Chinese Japonica Super Rice were measured in pot experiment. At every stage of root development, total absorption area, active absorption area, root oxidizing ability per plant, and bleeding rate in Shennong 265 and Shennong 606 were significantly higher than control cultivar. During the filling stage, Shennong 265 and Shennong 606 roots showed slower roots senescence and stronger physiological activity than the control. During the filling period both chlorophyll degradation rate and photosynthetic rate of Shennong 265 and Shennong 606 were significantly slower than those of control cultivar. Furthermore, root physiological activities showed a positive correlation with leaf chlorophyll content in Japonica Super Rice during filling periods, showing that Shennong 265 and Shennong 606 had advantages in root physiology and leaf photosynthesis characteristics compared with Akihikari and Liaojing 294.
