摘要
随着白及市场需求量的增加,为解决市场供需矛盾,白及组培苗繁育技术得到重视和广泛运用。从白及种子萌发及原球茎诱导、原球茎增殖分化、壮苗生根和炼苗移栽4个阶段综述了白及组培苗繁育技术的研究进展,并总结了各阶段优势技术及存在问题,展望了该领域未来的研究方向。
With the increase of Bletilla striata market demand,the contradiction between supply and demand of Bletilla striata seedling is daily outstanding.In order to solve the contradiction,tissue culture seedling breeding technology has been valued and widely used.This review summarized the progress on research of tissue culture of Bletilla striata including seed germination and culture condition,proliferation of clusters of buds,induction of rooting,transplanting of seedlings.Influential factors as well as optimum concentration and combination of the plant growth regulators and other exogenous additives in each stage were summarized.Advantage technology and problems of Bletilla striata tissue culture were pointed out.The future research direction in this field is prospected too.
