摘要
以樱桃番茄(L.Esculentum var.Cersiforme)的下胚轴和子叶的切段为外植体,在附加不同浓度激索的MS培养基上进行离体培养.结果表明,下胚轴和子叶的最佳不定芽诱导培养基为MS+IAA1.0mg/l+ZT1.0mg/l,且子叶外植体诱导愈伤组织及诱芽的效果好于下胚轴;不同品种间,以"黄洋梨"的诱导效果最好;较好的生根培养基为MS+IAA0.2mg/l.
Hypocotyls and cotyledons of Lycopersicon Esculentum var. Cerasiforme were used as explants for culture on MS media supplemented with hormone at different levels. The result showed that MS basal medium with IAA1.0mg/l ＋ ZT1,0mg/l had great effect on/be shoot formation. And the cotyledons have more effect than hypocotyls on callus and shoot formation. Among the different varieties, ＂yellow Yangli＂ have the best effect on shoot induction. The best medium inducting root was MS basal medium with IAA0.2mg/l.
