茶树杂交后代或诱变材料扦插繁殖,进行苗期的选择与鉴定,是茶树育种工作的一个重要环节。在苗圃,离体培养茶树插枝,茎切段形态学的下端再生根系,腋芽抽茎展叶,从而育成完整的植株。苗期植株性状的表现,干物质的形成,无不受到扦插材料的异质性和苗圃环境两方面变异因素的影响。各 Tea hybrids or mutagenic material cutting propagation, selection and identification of seedling stage is an important part of tea tree breeding. In nursery, in vitro cultivation of tea tree cuttings, stem cuttings at the bottom of the regeneration of the root morphology, axillary bud pumping stems exhibition leaves, and thus develop a complete plant. Seedling plant performance, dry matter formation, are subject to the cutting material heterogeneity and nursery environment two aspects of variation factors. each
