以探明茶树组织培养中不定器官分化为目的,研究了不同器官,不同茶季及不同节间基的切片的根的分化及其品种间的差异。(1)不同器官根分化率顺序为基切片(51%)>根切片(44%)>叶切片(29%)>子叶切片(o%)。 (2)从秋梢的不同节间采取的基三切片根的分化率与分化根数为:第1节间4.84%,0.11根;第2~5节间25.1 In order to explore the differentiation of adventitious organs in the tissue culture of tea, the root differentiation of different organs, different tea seasons and different internode sections and the differences among the cultivars were studied. (1) The order of root differentiation of different organs was base slice (51%)> root slice (44%)> leaf slice (29%)> cotyledon leaf slice (o%). (2) The differentiation rate and differentiation number of the roots of three basal slices taken from different internodes of autumn shoots were 4.84% and 0.11 in the first internode, 25.1
