| 摘 要： | 目的]优化马铃薯试管苗的生长培养基,提高马铃薯试管苗的质量。方法]配制了不同糖分含量的9种培养基对马铃薯中薯3号的茎段进行琼脂固体培养,观察试管苗的长势,研究不同糖分含量培养基对马铃薯试管苗生长的影响。结果]不同糖分含量的培养基对马铃薯试管苗生长的影响较明显,试管苗的生长状况不尽相同。马铃薯培养基+1/4 MS(NH4NO3+KNO3+KH2PO4)+0.4 mg/L6-BA+0.1 mg/LIBA+30 mg/LB9+4%糖处理的马铃薯试管苗的长势最好,节间均匀,叶面积大,茎秆粗壮,无玻璃化现象,其马铃薯产量最高,其次是马铃薯培养基+0.4 mg/L6-BA+0.1 mg/LIBA+30 mg/LB9+4%糖、MS+0.4 mg/L6-BA+0.1 mg/LIBA+30 mg/LB9+4%糖2个处理。结论]糖分含量为4%的培养基最有利于马铃薯试管苗的生长,苗壮、苗匀、苗齐,其保护地栽培成活率达100%,且马铃薯产量最高。

| Abstract: | Objective] The study aimed to optimize the growth medium of potato tube seedings and improve the quality of potato tube seedlings.Method] The 9 kinds of mediums with different sugar content were prepared to make the agar solid culture on the stem segment of potato variety Zhongshu 3,and the growth vigor of tube seedlings was observed to study the effect of those mediums on the growth of potato tube seedlings.Result] The effect of mediums with different sugar content on the growth of potato tube seedlings was obvious,and the growth condition of tube seedlings was not all the same.The growth vigor of potato tube seedlings in the medium treatment of potato medium 1/4 MS(NH4NO3 KNO3 KH2PO4) 0.4 mg/L 6-BA 0.1 mg/L IBA 30 mg/L B9 4% sugar was the best with the uniform internode,big leaf area,sturdily stem,no vitrification phenomenon and highest yield of potato,the following was the 2 treatments of potato medium 0.4 mg/L 6-BA 0.1 mg/L IBA 30 mg/L B9 4% sugar and MS 0.4 mg/L 6-BA 0.1 mg/L IBA 30 mg/L B9 4% sugar.Conclusion] The medium with 4% sugar content was most beneficial to the growth of potato tube seedlings,and the seedlings were strong,uniform and tidiness with the survival rate of transplanting seedlings in protected field reaching 100% and highest yield of potato. |
