Grain-leaf ratio is an important indicator of coordination between sources and sinks[5].It can be expressed as follows:grain-leaf ratio(grains/cm2)=grains per spike/the largest leaf area of a plant,and grain-leaf ratio(mg/cm2)=mass of a spike/the largest leaf area of a plant.Seen from Table 2,the grain-leaf ratio of Yugu 18 was 1.43 times higher than that of Jigu 19,and the difference was extremely significant,showing that the coordination between sources and sinks of Yugu 18 was better than that of Jigu 19.
