摘 要 ：籽粒干重增重率(Y)与距抽穗日数(x)的关系呈 S 型曲线,配合 Logisfic方程后发现,品种间强势粒的增重过程可用同一方程表示,而弱势粒增重过程的品种间差异显著,故不同品种的籽粒增重特征应集中反映于它们强、弱势粒位间增重模型差异的性质上。二棱大麦(Hordeum distichum)强、弱势粒问呈同步增重型,多棱大麦(H.vulgare)呈异步
Abstract:In 1981 and 1982,the process of increase of grain weight in 4 differentvarieties(types)of barley was investigated.It was found that the processesof strong-and weak-grains were different among varieties.1.For the strong-grain,the relationship between the filling rate ofgrain Weight and the number of
