图2 花部性状与主要传粉者体型大小在居群间的变异关系。A, 花冠长与传粉者体长的变异关系(r = -0.97, p = 0.024)。B, 雄蕊杠杆长与传粉者体长的变异关系(r = 0.99, p = 0.004)。C, 花冠口高与传粉者胸厚的变异关系(r = 0.92, p = 0.08)。D, 柱头高度与传粉者胸厚的变异关系(r = 0.89, p = 0.10)。

Fig. 2 Variation relationship of floral traits to body size of main pollinator’s among populations. A, relationship between corolla length and pollinator’s body length (r = -0.97, p = 0.024). B, relationship between staminal lever length and pollinator’s body length (r = 0.99, p = 0.004). C, relationship between corolla entrance height and pollinator’s body thickness (r = 0.92, p = 0.08). D, relationship between stigma height and pollinator’s body thickness (r = 0.89, p = 0.10).
