- 摘要:
- 以2个郁金香品种“阿波罗”和“琳?马克”为试材,用不同时期、不同部位、不同类型的郁金香鳞片作为外植体,以MS为基本培养基,分别添加不同质量浓度的6-BA、NAA、IAA和活性炭,研究不同外植体以及不同培养基对小鳞茎诱导的影响。结果表明:经春化处理后的鳞片作为外植体诱导小鳞茎的效果最好,鳞片部位以中层最适宜诱导小鳞茎;以带鳞茎盘的双鳞片作诱导小鳞茎的外植体效果最好;最适宜“阿波罗”小鳞茎诱导的激素组合为 MS+6-BA 2 mg/L+ NAA 2 mg/L+IAA 0.3 mg/L;最适宜“琳?马克”小鳞茎诱导的激素组合为 MS+6-BA 2 mg/L+ NAA 2 mg/L+IAA 0.1 mg/L;活性炭对小鳞茎的诱导有促进作用;最适宜的暗处理时间为 7 d。
- Abstract:
- Chosen two ‘Apeldoorn’and ‘Leen van der Mark’cultivars as test materials,different period,different position and different type of bulbs as explants,MS as basal medium,added the different concentration 6-BA,NAA,IAA and activated carbon respectively,the effects of different explants and media on bulblets induction of tulip scapes as experimental material were studied.The results showed that the vernalized scale was the best appropriate explant.Twin-scale with basal plate was the best appropriate explant and the cultivation effect of middle layer scale was the best.The most suitable medium for bulblets induction of‘Apeldoorn’was MS+6-BA 2 mg/L+NAA 2 mg/L+IAA 0.3 mg/L.The most suitable medium for bulblets induction of‘Leen van der Mark’was MS+6-BA 2 mg/L+NAA 2 mg/L+IAA 0.1 mg/L.Activated carbon had favourable effect on bulblets induction.The most appropriate date of darkness was 7 days.
