Anatomical and Morphological Development of ‘Manzanillo’ Olive Seed in Relation to Germination

Abstract

Microscopic examination of sectioned germinating olive seed ( Olea europaea L.) did not reveal differences from many other seed types. No seedcoat-imposed mechanical restrictions were found during germination. The seed was 4% and the embryo 1% of the mature, whole fruit dry weight. Maximum embryo dry weight was achieved by early October. Germination was 90% when the embryo had gained 60% of its final dry weight. No dormancy factors were evident in the excised embryos.
