Résumé : The growth and development under field conditions of the pods and seeds of two cvs of #Trigonella foenum graecum# are described. Samples were harvested at different stages of ripeness for the determination of dry matter, protein and free amino acid content. During maturation, reserves of solutes are established in the pod wall before the seeds begin their exponential phase of growth. Later, these reserves disappear, providing about 20% of the seed's requirements for nitrogen. SDS-electrophoresis was used to follow the formation of proteins and it was shown that the synthesis of storage proteins takes place prior to dehydration of the seed. Production soluble nitrogenous compounds precedes protein accumulation. Free amino acids follow the same pattern. 4-Hydroxyisoleucine represents nearly 80 % of free amino acid of dry seeds. The concentration does not decrease in the later stages of maturation of the seed but this unusual amino acid is absent in the storage proteins of the seeds.
