Abstract

Freshly cut disks of beetroot tissue develop high rates of respiration, uptake of phosphate and activity of the enzyme invertase after having been washed for 18 hours in 0.01 m potassium maleate.Incubation of the disks in solutions of indole-3-acetic acid or kinetin completely prevented the development of the higher activities in all 3 systems assayed, while incubation in gibberellic acid had no inhibitory effect. Using a series of synthetic plant growth regulating compounds it was possible to establish that there was no correlation between the activity of the compound as an auxin and the ability of the compound to prevent the development of the enhanced rates of metabolism.

摘要

刚切下的甜菜组织薄片在 0.01m 钾马来酸盐中清洗 18 小时后,呼吸作用、磷酸盐吸收和转化酶活性会迅速增强。将薄片在吲哚-3-乙酸或激动素溶液中孵育可完全阻止这 3 种系统中所有较高活性的出现,而在赤霉素溶液中孵育则没有抑制作用。使用一系列合成的植物生长调节剂进行实验,发现化合物作为生长素的活性与化合物防止代谢增强的能力之间没有相关性。
