Abstract
Summary: Changes in the free amino acid and amide composition of the developing hull and component parts of the seeds of garden pea, Pisum sativum cv. Melbourne Market, have been recorded. Major differences observed in comparison with field pea include the absence of O‐acetyl homoserine as a prominent component in the hull or seedcoats and the absence of an increase in the relative proportion of asparagine in ageing seedcoats or maturing embryos. Serine was more prominent in young hulls, mature embryos and seedcoats and embryo sac liquid than in field pea, while arginine was less prominent in the maturing cotyledons and the embryo axis.
