| Abstract: | The theory of three-combination structure was composed in yield components,photosynthetic characteristics and source-sink characteristics.On the basis of the three combination structures,a field trial was conducted to reveal the relationship among photosynthetic characteristics and yield component factors and yield potential of Denghai 601 hybrid with high yield potential beyond 18 450 kg/hm2 in the rain-fed and compensatory irrigation farming region of northwest Hebei province.The results showed that the v... |
