大部分吲哚乙酸 (IAA) 诱导的对切除根尖的抑制以及几乎所有对完整根的抑制都是 IAA 依赖性乙烯产生的结果。在某些条件下，IAA 的额外作用占了切除根尖抑制作用的一小部分。施加 IAA 后乙烯的产生取决于根内所施加的生长素的水平。有证据证实乙烯参与根部的向地性响应。
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.
