Abstract

A large portion of indoleacetic acid (IAA)-induced inhibition of excised root tips and virtually all such inhibition of intact roots are the result of IAA-dependent ethylene production. Under certain conditions an additional effect of IAA accounts for a small portion of the inhibition of excised root tips. Ethylene production in response to applied IAA is governed by the level of applied auxin found inside the root. Evidence is presented to confirm the participation of ethylene in the geotropic response of roots.

摘要

吲哚乙酸(IAA)对离体根尖的大部分抑制作用,以及对完整根的几乎所有抑制作用,都是 IAA 依赖乙烯产生的结果。在某些条件下,IAA 的额外作用解释了离体根尖抑制作用的一小部分。对施加的 IAA 的乙烯产生受根内施加的生长素水平的控制。有证据证实乙烯参与了根的向地性反应。
