摘要:

为建立甘薯茎尖分生组织培养与快繁体系,以甘薯品种心香为试验材料,剥离茎尖分生组织培养脱毒苗,并以MS为基础培养基,添加不同质量浓度的6-卞氨基腺嘌呤(6-BA)和萘乙酸(NAA),通过双因素随机区组试验筛选心香甘薯茎尖分生组织芽诱导和增殖生根的最适培养基。结果表明,心香甘薯适宜的芽诱导培养基为MS+0.5 mg·L-1 6-BA+ 0.1 mg·L-1 NAA,芽诱导率达到86.67%,成苗率为80.00%。最适宜的增殖生根培养基为MS+0.10 mg·L-1 6-BA+ 0.05 mg·L-1 NAA,在此培养条件下,叶片数为9.50个,主根数为7.17条,株高6.68 cm,根长38.94 cm,茎粗2.46 mm。成功建立了心香甘薯茎尖分生组织的组培体系,为后续心香甘薯茎尖脱毒奠定了基础。

Abstract:

To establish the meristematic tissue culture and rapid propagation system of Ipomoea batatas stem tip,the variety of Xinxiang was used as the material and its stem tip meristematic tissue was stripped to cultivate detoxified seedlings,and MS was used as the basal medium,with the addition of different mass concentrations of 6-BA and NAA,to screen the most suitable medium for bud induction and proliferation rooting of stem tip meristematic tissue culture by a two-factor randomized block test. The results showed that the suitable medium for bud induction of stem tip meristematic tissue of Ipomoea batatas variety Xinxiang was MS+0.5 mg·L-1 6-BA +0.1 mg·L-1 NAA,and the rate of bud induction was 86.67%,and the rate of seedling formation was 80.00%,respectively. The most suitable medium for proliferation rooting of Ipomoea batatas variety Xinxiang was MS+0.10 mg·L-1 6-BA+0.05 mg·L-1 NAA. Following the cultivation condition,the number of leaves was 9.50,the number of primary roots was 7.17,the height of the plant was 6.68 cm,the length of root was 38.94 cm,and the stem thickness was 2.46 mm,respectively. We established a comprehensive tissue culture system for stem tip meristematic tissue of Ipomoea batatas variety Xinxiang,laying a foundation for the subsequent development for apical meristem virus-free of Ipomoea batatas variety Xinxiang.
