菜豆豆荚和种子的生长发育可用以下参数来描述：鲜重和干重、长度、鲜重与长度之比和氮含量。荚果和种子的发育是相互独立的，也是相继发生的。荚果光合作用对荚果发育的贡献很小，但在重新固定呼吸释放的CO2方面可能很重要。荚果和种子似乎不仅仅是作为竞争的水槽。种子中的氮积累只有在豆荚中停止时才开始。本文还讨论了实现监管的途径。提出了氮肥运筹促进种子生长的建议。
The growth and development of pods and seeds of Phaseolus vulgaris are described by the following parameters: fresh and dry weight, length, ratio of fresh weight to length and nitrogen content. Pod and seed development are independent and sequential. Pod photosynthesis contributes only marginally to pod development, but may be significant in refixing CO2 released in respiration. Pods and seeds do not seem to act simply as competing sinks. Nitrogen accumulation in the seeds begins only when it has ceased in the pods. Ways in which regulation may be achieved are discussed. Manipulation of nitrogen fertilization to enhance seed growth is suggested.
