自从 Haberlandt(1913,1922)利用马铃薯块茎组织证巨额可在植物材料中诱导离体细胞分裂之后,不少作者进行了大量试验。利用几乎所有离体技术和外植体资源取得的结果,都清楚地表明,马铃薯这一作物特别适用于离体培养和突变育种。由单个或少数细胞再生植株,是解决诱变处理后形成嵌合体问题的理想途径。无性繁殖又有利于保持其周缘或细胞质突变。此外,与活体系统相比,离体培养具有可能在无菌及标准化条件下处理大量群体的优
Since Haberlandt (1913, 1922) has used tuberous tuberous explants to induce large numbers of ex vivo cell divisions in plant material, a number of authors have conducted extensive trials. The results obtained with almost all ex-situ techniques and explant resources clearly show that the potato crop is particularly suitable for both in vitro and mutant breeding. Plant regeneration by single or few cells is the ideal way to solve the problem of chimera formation after mutagenesis. Asexual reproduction is also conducive to maintaining its peripheral or cytoplasmic mutation. In addition, in vitro culture has advantages over living systems in that it is possible to treat large numbers of groups under sterile and standardized conditions
