We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

结果表明，诱导章丘大葱子叶产生愈伤组织、愈伤组织的继代培养、愈伤组织芽分化、芽点的伸长及诱导生根的最佳培养基及激素配比分别为：MS+2，4-D 2.0mg/L+KT 0.5mg/L、MS＋2，4-D 2.5mg/L＋KT 0.5mg/L、MS+2，4-D 0+KT 1.0mg/L、MS+KT 0.5mg/L和MS基本培养基；试管苗经驯化移栽后，共有22株成活，成活率为92%，对成活的再生植株进行形态学、叶片气孔及根尖染色体鉴定表明，共有3株发生变异，其中2株为外部形态上的变异，而另一株为染色体的加倍变异。
