Abstract

Harvesting seed of ‘Manzanillo’ olive (oleo europaea L.) at the end of October, when embryo growth was complete, gave optimum germination and extended storage life with lower germination rates and shorter storage life before or after this date. Optimum germination occurred at 15°C for whole seed and 25° for excised embryos; both grew faster at 25° after germination. Seed and excised embryos germinated equally well in light or dark.

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.
