摘要
Four explants, stem, leaf, bud and cotyledons of six wild species of Helianthus viz., H. nuttallii, H. mollis, H. debilis, H. divaricatus, H. maximilliani and H. praecox, were cultured on different media for callus development. Calli were regenerated on Murashige-Skoog (MS) medium supplemented with 1.0 mg/l 6-benzylamino purine (BAP), 0.1 mg/l gibberellic acid (GA3), 500 mg/l casamino acids (CA) and 40 mg/l adenine sulphate (AS) (R medium). Regenerated plantlets were grown on MSD4 medium to form complete plants. The plants were rooted on MS basal hormone free and BGS media.
