Abstract

Barley embryos, measuring 90 Fz in length, grew and became differentiated on a phosphate-enriched White's medium which was fortified with glutamine and alanine as major sources of organic nitrogen, and lesser amounts of five other amino acids. The pH of the medium was a critical factor in differentiation. On this medium, excised barley embryos developed more rapidly than embryos remaining in vivo, or embryos grown on media containing coconut milk.
