研究培养基和激素对甘蔗梢部幼茎腋芽萌发、丛芽产生、芽苗增殖及小苗促根的影响 ,以筛选出较佳激素组成 .结果表明 ,液体培养基优于固体培养基 .在供试激素质量浓度范围内 ,附加 0 .0 5和 1.0或 2 .0 mg· L-1BA最有利于腋芽萌发 ;附加 2 .0或 3.0 mg· L-1BA最有利于丛生芽的产生和芽苗的增殖 ,但 1.0 mg· L-1BA最有利于培育壮苗 ;附加 4 .0 mg· L-1NAA最有利于芽苗生根 .本研究可为甘蔗离体快速繁殖提供技术 The effects of medium and hormone on the axillary bud emergence, shoot formation, shoot bud emergence and seedling emergence of sugarcane shoots were studied to screen out the best hormone composition.The results showed that the liquid medium was better than the solid medium In the test hormone concentration range, 0.05 and 1.0 or 2.0 mg · L -1 BA were most helpful for the axillary bud germination, and 2.0 or 3.0 mg · L -1 BA was the best for the production of buds and shoots , But 1.0 mg · L-1BA was the most conducive to the growth of strong seedlings, and the addition of 0.4 mg · L-1 NAA was most beneficial to rooting of shoots.
