摘要
在大田条件下 ,研究了不同类型粳稻品种生育后期的光合特性 ,探讨了灌浆期和成熟期各品种叶绿素含量、气孔阻力、蒸腾速率以及光合速率对产量的影响。结果表明 ,新品种沈农8801生育后期光合特性较为理想 ,具有较大的叶面积指数。
Under field conditions, the photosynthetic characteristics at late growth stage among different types of rice varieties and the effects of chlorophyll content, stomatal resistance, transpiration rate and photosynthetic rate on the yield were studied in this paper. The results showed that Shennong 8801, a new rice variety, was ideal in the photosynthetic characteristics,with higher levels of LAI, chlorophyll content and resistance ability.
