An ontogenetic study of canavanine formation in the fruit of jack bean, Canavalia ensiformis (L.) DC. was conducted. Evidence was presented to show that the ovary wall is the reservoir for seed canavanine. The testa possesses sufficient canavanine to account for the continued elevation in seed canavanine after the pod senesces. The seed canavanine concentration is not constant inasmuch as the canavanine content per milligram dry weight or soluble protein increases abruptly with seed growth and levels off only with the onset of fruit ripening.
对刀豆（Canavalia ensiformis（L.）DC.）果实中天冬氨酸的形成的个体发生进行了研究。有证据表明，子房壁是种子中天冬氨酸的储存库。种皮含有足够的天冬氨酸，足以解释豆荚衰老后种子中天冬氨酸的持续升高。种子中天冬氨酸的浓度不是恒定的，因为每毫克干重或可溶性蛋白质中天冬氨酸的含量随着种子的生长而突然增加，只有在果实成熟时才趋于稳定。
