Types of Embryo Culture
According to Pierik (1989), there are in principle two types of embryo culture.
I. Culture of Immature Embryo:
This type of embryo culture is mainly used to grow immature embryos originating from unripe or hybrid seeds which fail to germinate. Excising such embryos is difficult and generally a complex nutrient medium is required to raise them to produce plants.
II. Culture of Mature Embryos:
Mature embryos are excised form ripe seeds and cultured mainly to avoid inhibition in the seed for germination. This type of culture is relatively easy as embryo requires simple nutrient medium containing mineral salts, mineral salts, sugar and agar for growth and development.
