The results indicated:0.1 mg/L 2,4-D or 0.1 mg/L 2,4-D+0.2 mg/L KT was optimal to induct the callus of carrot hypocotyls.The majority of the callus induced on the medium containing 0.1 mg/L 2,4-D regenerated embryoid,whereas,the callus induced on the medium containing 0.1 mg/L (2,4-D)+0.2 mg/L KT produced adventive buds.During the growth of regenerated plant,MS medium is available for rooting of seedling,and seedling regenerated on B5 medium must be placed on the B5 medium containing 0.1% IBA to develop root.
试验结果表明:0 1mg/L2,4 D或0 1mg/L2,4 D+0 2mg/LKT的激素组合有利于胡萝卜下胚轴的愈伤组织诱导;在0 1mg/L2,4 D的培养基上形成的愈伤组织主要以胚状体的形式再生,而在含0 1mg/L2,4 D+0 2mg/LKT激素组合的培养基上形成的愈伤组织主要以发生不定芽的方式再生;再生过程中,B5基本培养基上的苗子不易生根,需要附加0 1mg/L的IBA,而在MS培养基上苗子可直接形成根。
