The Seed: Germination, each other separated by a period of relative metabolic inactivity called quiescence, and are essentially different phases of the continuing process of embryo growth and development. Obviously, the nature of the pre-quiescence embryo bears very heavily on early germination behaviour and its control,

It was suspected that the pollen tube, apart from carrying the sperm nuclei, also contributes to the growth of ovary by supplying auxins.
