摘要: 为建立北美海棠松散型愈伤组织诱导体系,以北美海棠组培苗的叶片、茎段和叶柄为外植体,在含有不同浓度2,4-D的培养基上进行愈伤组织的诱导,并在含有不同浓度的2,4-D、BA、GA3培养基上进行松散型愈伤组织诱导。结果显示,以叶柄为外植体的愈伤组织诱导率最高,为100.0%;在浓度为2.0 mg/L的2,4-D的培养基上愈伤组织生长最快;在MS+30.0 g/L蔗糖+100.0 mg/L Vc+1.0 mg/L 2,4-D+0.5 mg/L BA+1.0 mg/L GA3的培养基上可以诱导出结构松散、生长速度最快的愈伤组织。

Abstract: In order to establish a callus induction system of North American begonia, the leaves, stems and petioles of North American begonia tissue culture seedlings were used as explants, and callus induction was carried out on medium containing different concentrations of 2,4-D. Loose callus induction was performed on medium with different concentrations of 2,4-D, BA, and GA3. The results showed that the callus induction rate of petiole explants was 100.0%; the callus growth was the fastest on 2,4-D medium with concentration of 2.0 mg/L. And on MS+30.0 g/L sucrose+100.0 mg/L Vc+1.0 mg/L 2,4-D+0.5 mg/L BA+1.0 mg/L GA3, the callus with loose structure and fastest growth rate can be induced.

Key words: North American begonia, explants, hormone, callus
