| 摘 要： | 以11份萝卜（Raphanus sativus）基因型为材料进行子叶离体培养研究,筛选出具有较高再生率的基因型进行实验,考察基因型、外植体类型、激素配比和苗龄等因素对萝卜再生的影响。结果表明：萝卜离体再生的最佳外植体为全子叶-叶柄,最适苗龄为4天,最适培养基为MS＋6mg·L-16-BA＋0.05mg·L-1NAA,再生率高达86.95%,再生系数为1.80。该研究为进行萝卜遗传转化实验奠定了良好基础。

| Abstract: | We studied in vitro culture regeneration from cotyledons of 11 genotypes of radish.Those genotypes,which have a high rate of regeneration,were used as the test materials for subsequent experiments of explant type,hormone ratio,and seedling age.The regenerated plantlets,which generated roots well,were transplanted into the field.The entire cotyledon with a petiole is the optimal regeneration explant.Four days of seedling age is suitable to induce adventitious shoots.The maximum frequency of shoot regeneratio... |
