CHAPTER I
DEVELOPMENT OF SEED

1 Introduction

1. Background
A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes the process of reproduction in seed plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule. Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions. Seeds fundamentally are a means of reproduction and most seeds are the product of sexual reproduction which produces a remixing of genetic material and phenotype variability that natural selection acts on. Storage of reserves food is one of the main functions of the seed. Storage of reserves food is closely related to the process of ripening and seed filling. Knowledge of this is necessary as a preparation of the breeder in order to produce seeds / seed which has the power and speed of germination (viability) is high. In the process of ripening and seed filling are the factors that affect the optimum level of process. These factors are internal factors derived from the plant (seed) itself and the external factors which is more oriented to the environment. 2. Practical purposes.
