为了确定在开花和结果的变化程度，在自然生长的植物的雌蕊异株灌木Hebe subalpina之间的枝条，花和果实的生产进行了测量的两个性别形态。两种形态的植物内的花数各不相同，但虽然水果生产是一样的变量，在雌性植物内的花数，水果生产比花数的“男性”（或完美的花）形态，平均产生较少的水果。还测量了各种各样的枝条特征，以确定开花和结果的变化是否与枝条之间的差异有关，这些枝条在植物内的资源状况和/或层次结构（...）
To determine the degree of variation in flowering and fruiting among shoots within naturally growing plants of the gynodioecious shrub Hebe subalpina, flower and fruit production were measured on both sexual morphs. Flower number varied within plants on both morphs, but while fruit production was just as variable as flower number within female plants, fruit production was more variable than flower number within the'male' (or perfect-flowered) morph, which produced fewer fruits on average. A variety of shoot characteristics was also measured, to determine whether the variation in flowering and fruiting was related to differences among shoots in their resource status and/or hierarchy within the plant (...)
