The coconut endosperm is a nuclear type. In very young coconut fruit (about 50mm long) the endosperm is found as a clear fluid in which float numerous nuclei of various sizes. This fluid is compactly filling the embryo sac in which the embryo is developing.
In most flowering plants, the central cell contains two haploid nuclei, which fuse prior to or at fertilization. The fusion of this homodiploid nucleus with the sperm nucleus results in a triploid primary endosperm nucleus with two maternal and one paternal genome complements (2m:1p).The endosperm is an intriguing botanical tissueâ (Birchler, 1993). The endosperm is an ephemeral tissue, restricted to the period of seed production and germination. It is largely consumed either by the developing embryo or after germination by the seedling (Lopes and Larkins, 1993).
