本文描述了被子植物地上部钙平均相对含量在序数水平上的变化。数据来源于文献中的研究，其中拍摄的钙含量的两个或更多个物种进行了比较，并从水培实验中，植物被选中代表的相对数量的物种内的每个被子植物命令。在所有被子植物中，大部分的变化发生在地上部钙含量的水平和以上的顺序。相对地上部钙含量和方差相关文献和实验数据。总体而言，鸭茅类单子叶植物的Ca含量低于其他单子叶植物或真双子叶植物。这些结果被用来说明如何生理和生态的假设，可以制定使用文献数据。
This study describes the variation in the mean relative shoot Ca content within the angiosperms at the ordinal level. Data were derived from studies in the literature in which the shoot Ca content of two or more species had been compared, and from a hydroponic experiment in which plants were selected to represent the relative number of species within each angiosperm order. Across all angiosperms, most of the variation in shoot Ca content occurred at and above the level of the order. Relative shoot Ca contents and variances correlated between literature and experimental data. In general, orders of commelinoid monocots had lower Ca contents than other monocot or eudicot orders. These results are used to illustrate how physiological and ecological hypotheses can be formulated using literature data.
