植物组织培养技术近年来进展很快,对于通过组织培养技术以改良作物的可能与潜力更引起人们广泛的注意。叶片组织取材方便,是从事组织培养以及进行体细胞遗传研究的好材料。特别是Shepard,Bidney和Shahin从马铃薯叶肉原生质体再生植株群体中发现了极高频率的变异,并从中选出了一批在块茎特性、成熟期、茎蔓生长习性等方面具有优异性状的原生质体无性系。如果这一现象具有普遍性,则无疑具有重大的理论与实践意义。但是,对于叶组织离体培养中去分化与再分化的内外规律在目前尚不十分
Plant tissue culture techniques have progressed rapidly in recent years and have drawn much attention to the potential and potential of tissue engineering techniques to improve crops. Leaf tissue drawn convenient, is engaged in tissue culture and good genetic material for somatic studies. In particular, Shepard, Bidney, and Shahin found extremely high frequency variation in the population of potato mesophyll protoplast regenerated plants and selected a group of protoplasts with excellent traits in tuber traits, maturation, growth of stems and vines Clones. If this phenomenon is universal, it undoubtedly has great theoretical and practical significance. However, the internal and external rules of dedifferentiation and re-differentiation in leaf tissue culture in vitro are not yet very good
