摘要：

The activity of the enzymes 5''-nucleotidase (EC 3.1.3.5), adenosine nucleosidase (EC 3.2.2.7), adenine phosphoribosyl transferase (EC 2.4.2.7) and acid phosphatase (EC 3.1.3.2) was determined in sections of tomato plant (Lycopersicon esculentum Mill. cv. Bellina). The distribution of the enzymes changed markedly during development and a role for these enzymes in cytokinin metabolism is suggested.
