The process of seed germination includes the following five changes or steps. embryo. The modern technique of tissue culture can be used to grow virus-free plants. s. tored food. Propagation by Seed In fruit plants, the propagation by seed is primarily done to raise rootstocks required for producing grafted or budded plants. It has a tough covering that protects the embryo. Downloaded: 687. Seed Propagation. However, some fruit plants (papaya) are conventionally propagated by seeds. banana, grape, fig, and chrysanthemum. Many producers of fruit and vegetables (F&V) and/or flowers and ornamentals (FO) also grow and sell propagation materials for F&V and FO, therefore GLOBALG.A.P. An efficient protocol was established for in vitro propagation of C. mastersii using seed as the starting material. a. Asexual propagation enables the production of plants that would otherwise be difficult or impossible because the plant does not produce viable seed or the seed is difficult to germinate. vegetative propagation. This method is so termed "sexual" because there is the involvement of the sexes, referring to the contribution of both the male and female gametes in the production of new plants.
