EMBRYOGENESIS AND PLANT-REGENERATION FROM CALLUS-CULTURES DERIVED FROM UNPOLLINATED OVARIES OF HYOSCYAMUS-MUTICUS L

Unpollinated ovaries of Hyoscyamus muticus L. (commonly known as Egypt ian henbane) were cultured on Murashige and Skoog and Bourgin and Nits ch media supplemented with various growth hormones to study the organo genesis, embryogenesis and regeneration of plantlets, Embryogenesis wa s reported for callus grown on both media containing 0.05 mg/l alpha-n aphthaleneacetic acid and 0.5 mg/l 6-benzylaminopurine, Differentiatio n of roots and shoots from the calli also occurred in these media, Alb inism or chlorophyll deficiency and variation in ploidy level were obs erved among the ovary-derived plantlets.
