Abstract

The properties of two strains of carrot (Daucus carota) callus are presented. One has a very low acid invertase activity which is accompanied by differences in morphology and metabolic rate, but not in growth rate. We conclude that one of the main functions of plant acid invertases is in controlling the levels of sugars which, by interaction with hormones, affect differentiation, both morphological and biochemical. The effect of tris on sucrose metabolizing enzymes, and the cause of the "sucrose effect" are considered.

摘要

本文介绍了两株胡萝卜（胡萝卜属）愈伤组织的特性。其中一株酸性转化酶活性极低，伴随着形态和代谢速率的差异，但生长速率无差异。我们得出结论，植物酸性转化酶的主要功能之一是控制糖的水平，糖通过与激素相互作用，影响形态和生化方面的分化。文中还考虑了三羟甲基氨基甲烷对蔗糖代谢酶的影响以及“蔗糖效应”的原因。
