图1 Gompertz方程对4种延绿类型品种旗叶衰老过程的拟合曲线 g1~g4分别代表延绿、中等延绿、中等早衰和早衰类型Gompertz拟合的曲线; gla_g1 vs t1、gla_g2 vs t2、gla_g3 vs t3和gla_g4 vs t4分别代表这4种延绿类型品种不同日龄下的%GLA。

Fig. 1 Curve fitting flag leaf senescence process by Gompertz model for four types of stay green varieties g1 to g4 represent curves fitted by Gompertz model for SG, MSG, MNSG, and NSG types, and gla_g1 vs t1, gla_g2 vs t2, gla_g3 vs t3, and gla_g4 vs t4 represent %GLA values of the four variety types, respectively.
