- 摘要:
- 为建立并优化茄子高频再生体系,研究以茄子品种哈农杂茄2号和哈农杂茄3号为材料,利用不同的外植体和植物生长调节剂组合,探讨影响茄子再生频率的主要因素。结果表明:茄子最佳再生子叶最适分化培养基为MS 0+6-BA 1 mg.L-1+KT 2 mg.L-1;下胚轴最适分化培养基为MS 0+KT 2 mg.L-1,再生苗最佳生根培养基为1/2MS+IAA 0.1 mg.L-1,且下胚轴的分化效率高于子叶。
- Abstract:
- In order to establish and optimize the high-frequency regeneration system of eggplant,taking cotyledonary petiole and hypocotyl explants of Hanongzaqie 2 and Hanongzaqie 3 as materials,the shoot regeneration frequencies of two eggplant(Solanum melongena L)cultivars were examined to discuss the factors affecting regeneration rate.The results showed that the optimum shoot inducing mediums for cotyledons was MS 0+6-BA 1 mg.L-1+KT 2 mg.L-1;the optimum shoot inducing mediums for hypocotyls was MS 0+KT 2 mg.L-1,the best rooting medium for regeneration seedling was 1/2MS+IAA 0.1 mg.L-1.And the differentiation of hypocotyls was higher than that of cotyledons.
