The embryonic axis plays an important role in the processes of starch degradation. Before germination starts, the starch granules of chickpea cotyledons have an almost smooth surface. As germination progresses, membrane‐like material is deposited on the granules from the adaxial to the abaxial face of the cotyledon. At 10 days after the start of germination, the starch granules disappear, giving rise to numerous polyhaedral starch bodies. When excised cotyledons are cultured, a pronounced temporal delay occurs in these events.
