Abstract

Each inflorescence on Lotus corniculatus commonly aborts about half of its immature fruits. Compared to random patterns of fruit abortion, natural patterns of fruit abortion produce mature fruits that contain significantly more seeds. Moreover, these progeny are more likely to germinate, are more vigorous as seedlings, and have greater reproductive output as adults. These results indicate that L. corniculatus selectively aborts those fruits with the fewest seeds and, by doing so, increases the average quality of its offspring.

摘要

百脉根的每个花序通常会使其约一半未成熟果实败育。与随机的果实败育模式相比，自然的果实败育模式产生的成熟果实含有明显更多的种子。此外，这些后代更有可能发芽，作为幼苗更具活力，成年后具有更高的繁殖产量。这些结果表明，百脉根会选择性地使种子最少的果实败育，通过这样做来提高其后代的平均质量。
