In a study of Cynoglossum officinale L. it was found that the number of seeds per flower increased with plant weight, and that flower production was inversely related to the number of seeds per flower. As a result, the number of seeds and total seed weight increased proportionally with plant weight. Seed size was not related to plant weight. Differences in seed size within the individual were, in part, related to the position of the seed on the cyme and not related to the number of seeds within a flower. The relationship, between plant size and female fitness found in this study is discussed in relation to life-history theory.
在一项关于药用琉璃草（Cynoglossum officinale L.）的研究中发现，每朵花的种子数量随植株重量增加而增加，而花的产量与每朵花的种子数量呈负相关。因此，种子数量和种子总重量与植株重量成比例增加。种子大小与植株重量无关。个体内部种子大小的差异部分与种子在聚伞花序上的位置有关，而与一朵花内的种子数量无关。本研究中发现的植株大小与雌性适合度之间的关系结合生活史理论进行了讨论。
