Abstract

When added at 3.10(-6) mM to auxin-starved suspension cultured carrot (Daucus carota L.) cells, the steroid hormone 24-epibrassinolide (BR) induces cell enlargement but not cell division.This is at variance from the effect of 2,4-D which, in the same experimental conditions, restores cell division without having any effect on cell enlargement.Furthermore, in the tested experimental conditions, the effect of BR is dominant over the effect of 2,4-D when the two hormones are simultaneously supplied to the auxin-starved culture.

摘要

当添加到 3.10(-6) mM 到生长素饥饿的悬浮培养胡萝卜（Daucus carota L.）细胞中时，甾体激素 24-表油菜素内酯（BR）诱导细胞增大而不诱导细胞分裂。这与 2,4-D 的作用不同，在相同的实验条件下，2,4-D 恢复细胞分裂而对细胞增大没有任何影响。此外，在测试的实验条件下，当同时向生长素饥饿的培养物中提供这两种激素时，BR 的作用优于 2,4-D 的作用。
