What is Embryo culture?

Embryo culture:

The growth of any species in its embryonic stage in an artificial medium to enhance its survival is called embryo culture.

1. Excision of embryos of different ages from the environment of the ovule and their culture under aseptic conditions in media of known chemical composition has advanced our understanding of the nutrient requirements essential for the continued growth of embryos.
2. Hormones, amino acids, vitamins, and other substances have been empirically used as supplements to a mineral salt medium to promote growth in the culture of embryos of different ages of a wide spectrum of species.
3. The growth requirements of embryos seem to represent variations of the theme that mature embryos have less exacting requirements for growth in culture than progressively younger embryos.
4. Indeed, seed embryos of many plants can easily be nurtured to the seedling stage by the simple expedient of culture in a nutrient medium containing just mineral salts and sucrose.
