Endogenous levels of cytokinin nucleotides in an anise cell culture were determined during proembryonal, as well as embryonal development. In both cultures the maximum level of isopentenyladenine nucleotides was found during the first four days of incubation which correlated with the beginning of logarithmic growth (embryonal: 8 ng g(-1) tresh weight; proembryonal: 17.4 ng g(-1) fresh weight). The concentration of zeatin nucleotides remained constant at a very low level. The present data and those of Ernst et al. (1984) and Ernst and Oesterhelt (1984) are concerned in ascribing a major role to cytokinins in cell division, but not in embryo differentiation.
在胚胎前和胚胎发育过程中，测定了茴香细胞培养物中细胞分裂素核苷酸的内源性水平。在两种培养物中，异戊烯基腺嘌呤核苷酸的最高水平都出现在孵育的前四天，这与对数生长期的开始相关（胚胎：8ng/g 鲜重；胚胎前：17.4ng/g 鲜重）。玉米素核苷酸的浓度保持在非常低的水平。目前的数据以及 Ernst 等人（1984 年）和 Ernst 和 Oesterhelt（1984 年）的数据都表明细胞分裂素在细胞分裂中起着重要作用，但在胚胎分化中不起作用。
