AIC values of different GLS models of growth for each morphology.

Best-fit models with lowest AIC values for each morphology are bolded and underlined. “*” Denotes an interaction between two variables.针对每个形态学（morphology）类别，赤池信息准则（Akaike Information Criterion, AIC）值最低的最优拟合模型均以加粗且下划线的形式标注。符号"*"表示两个变量间的交互效应。
