表3 植物属性的计量单位、一般数值范围、要求的最小重复数和推荐的重复数。在最小重复数和推荐重复数中, 第一个数值代表个体数, 第2个数值代表器官数。此表基于Cornelissen等(2003a)、Pregitzer等(2002)以及He等(2006b)等归纳。

Table 3 Metric units, range, minimum and suggested replications for plant trait measurements. The first and second numbers in the minimum (and suggested) replications represent replications of individuals and organs, respectively. This table is summarized from Cornelissen et al. (2003a), Pregitzer et al. (2002), and He et al. (2006b)
