Influence of media and growth regulators on somatic embryogenesis and plant regeneration for production of primary triticales uri icon

abstract

  • Basal media and plant growth regulators were tested for the promotion of somatic embryogenesis from immature wheat-rye hybrid embryos. Influence of growth regulators and chilling on plant regeneration were tested on two media. A medium containing four amino acids - glutamine, arginine, glycine and aspartic acid - as the nitrogen source, promoted the production of, on average, twice as much embryogenic callus as the other media, and somatic embryos developed well. The growth regulator dicamba was significantly better than 2,4-dichlorophenoxyacetic acid in promoting somatic embryogenesis and subsequent plant regeneration. Germination of somatic embryos on both regeneration media was enhanced by cold treatment. Supplementing 190-2 plant regeneration medium with a combination of alpha-naphthaleneacetic acid + benzyladenine, indole-3-acetic acid + kinetin or indole-3-acetic acid + zeatin resulted in equally high germination rates.
