Abstract
The germination of maize seed harvested were measured at different development stages, including fresh seed, embryo, seed minus coat and dry seed. Embryo germinated as young as 15-17DAP, but the germination of fresh seed was very low. Seed minus coat could germinate, but seedling grew slowly. The loss of water from seed tissues played some roles in germination. During seed development germination increased following the decline of water content, and dry seed which had acquired tolerance of desiccation germinated and grew normally. Fresh immature seed also can germinate, but that the expression of this germination capacity took longer than for dry seed. Drying was not a prerequisite for germination, but accelerated the transition from development to germination.
