近年来,随着植物组织和细胞培养研究的深入开展和农业生产上的需要,将植物细胞和组织培养物用于种质贮存或其它方法研究,越来越受到重视。把组织培养技术用于农作物种质保存的方法有两种:维持培养物最小量生长和超低温冷冻保存。本文介绍利用甘薯茎尖分生组织培养获得的无性繁殖植株,经离体单节繁殖,培养在附加有不同浓度和不同种类化
In recent years, with the further development of plant tissue and cell culture research and the need of agricultural production, plant cells and tissue culture are used for germplasm storage or other methods research, more and more attention. There are two ways of using tissue culture techniques for the conservation of crop germplasm: keeping the culture in minimum growth and cryopreservation. This article describes the use of sweetpotato shoot apical meristem obtained clonal plants, in vitro propagation of single, cultured in additional with different concentrations and different types of
