- 摘要:
- 以胡萝卜“七寸人参”为试材,探讨了不同外植体、激素、培养基、光照对胡萝卜愈伤组织诱导的影响。结果表明:胡萝卜愈伤组织的诱导以下胚轴为外植体为宜;在添加2,4-D 1.0 mg/L和KT 0.5 mg/L的MS培养基上愈伤组织的诱导频率为100%,且愈伤组织生长良好,增殖快速;光照对愈伤组织的诱导没有影响,但却进一步阻碍了愈伤组织的增殖生长。
- Abstract:
- Calli induction and proliferation from explants were regulated by several factors,the effect of hormones,different explants,light and media on calli induction from Daucus carota L.was investigated.The results indicated that the optimal explant for calli induction from carrot was hypocotyl rather than cotyledon.The optimal medium for calli induction was MS agar medium supplemented with 3% sucrose,2,4-D 1.0 mg/L and KT 0.5 mg/L.The induced calli frequency of the carrot hypocotyls on this medium was 100%.Light had no effect on calli induction but it influenced calli proliferation.
