| Abstract: | 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. |
