| 摘 要： | 以早熟桃品种西选一号胚为外植体,对愈伤组织的诱导、继代保持和分化进行了研究。结果表明:2,4-D浓度为2.0mg.L-1的MS培养基是愈伤组织诱导的最适宜培养基,诱导率最高,达90.2%,诱导的愈伤组织质量好;将2,4-D浓度降低至1.0 mg.L-1,采用MS、WPM 2种培养基进行交替继代,可以使愈伤组织长期保持,但这种愈伤组织不能分化出芽。

| Abstract: | The calli from the embryos of early peach Xixuan 1 were induced and maintained.The results showed that the MS medium added 2,4-D was optimcal for induction of calli,whose inducing rate of calli was the highest(90.2%),the quality of calli was better than the other medium;that the calli sub-cultured alternately on MS/WPM medium whose concentration of 2,4-D was decreased to 1.0 mg·L~(-1) in inducing media could be maintained for long time,but the buds didn't differentiate from the calli sub-cultured. |
