本研究以花椰菜无菌苗顶芽为外植体， 诱导出不定芽， 进行了快速繁殖， 并对影响试管苗素质和繁殖系数的因素作了探讨。试管苗在 Ｍ Ｓ－ １９９ 培养基上，每代每月繁殖系数达５ 倍多，在无激素的 Ｍ Ｓ培养基上生根率达到９８％ 以上， 批量移栽平均成活率达到９８％ ， 再生植株在田间正常结球， 开花结籽， 具有良好的遗传稳定性。
In this study, cauliflower aseptic shoots as explants to induce adventitious buds, rapid propagation, and factors that affect the quality of test tube plantlets and reproductive coefficients were discussed. The test-tube seedlings grew more than five times per month on the M-199 medium with more than 98% of rooting rate on steroid-free M S medium and 98% on average. The regenerated plants In the field of normal ball, flowering and seed, with good genetic stability.
