| Abstract: | With S 3307 sprayed on rice leaves during ripening it is showed that the senescence of flag leaves was retarded which was reflected by chlorophyll content increasing, photosynthtic rate enhanceidy, activity of SOD promoting and MDA content decreasing. The number of grains per ear and the weight of 1000-gains were increased, which resulted in yield increased around 8.3-13.6%. |
