| 摘 要： | 为培育马铃薯健壮试管苗和长期保存马铃薯种质资源，以马铃薯脱毒试管苗为材料，比较了不同质量浓度的PP333（多效唑），CCC（矮壮素）和Pix（缩节胺）对马铃薯试苗生长和保存的作用．结果表明：培养基中CCC质量浓度为200．00mg／L，Pix质量浓度为30．00～90．00mg／L时适合于培养壮苗；培养基中PP333质量浓度为0．15～1．20mgm时对增加马铃薯的节位、茎粗效果明显，但叶片过大、气生根过多而易出现早衰；培养基中CCC质量浓度为1200．00mg／L，PP333质量浓度为4．80mg／L时，马铃薯脱毒试管苗保存时间最长可以达到300d．

| Abstract: | The effects of plant retardant PP333 and CCC and Pix on the in vitro growth of virus-free potato plantlets were examined.The results showed that CCC at 200.00 mg/L and Pix at 30.0~90.0 mg/L were fit for the culture of vigorous plantlets.PP333 at 0.15~1.20 mg/L have distinct effects on the gain of stem node number and diameter,but the plantlets leaf is too large and the plantlets tend to senesce prematurely.CCC at 1 200.0 mg/L and PPP333 at 4.80 mg/L were favorable for the long-term preservation of virus-free potato plantlets in in vitro culture.In this medium,the potato plantlets can preserve 300 days long. |
