The zeatin and zeatin riboside content of tomato (Lycopersicon esculentum Mill.) root exudates were determined at different stages of development. Zeatin riboside was found to be the major translocational form of cytokinin in the xylem during early vegetative growth. During flower bud formation this cytokinin decreased markedly in concentration so that, at anthesis, there was no appreciable difference in the zeatin and zeatin riboside concentration in the root exudate.
番茄（Lycopersicon esculentum Mill.）根渗出物中玉米素和玉米素核苷的含量在不同的发育阶段进行了测定。在早期营养生长过程中，玉米素核苷被发现是木质部中细胞分裂素的主要运输形式。在花芽形成过程中，细胞分裂素的浓度显著下降，以至于在开花时，根渗出物中玉米素和玉米素核苷的浓度没有明显差异。
