Abstract

A red light-induced, far red reversible stimulation of proton efflux from apical segments of etiolated Avena sativa L. cv. Victory coleoptiles was observed. The acidification responses to red light and also to auxin were not the consequence of respired CO(2). The response to red light was strongly inhibited by cycloheximide and carbonyl cyanide, m-chlorophenyl hydrazone, but mannitol had a stimulatory effect. Red light and auxin applied together yielded a greater than additive response, in comparison to the effects of the two stimuli applied separately.

摘要

观察到红光诱导的、远红光可逆的黄化燕麦(Avena sativa L. cv. Victory)胚芽鞘顶端节段质子外流刺激。对红光以及生长素的酸化反应并非呼吸产生的二氧化碳所致。环己酰亚胺和羰基氰化物间氯苯腙强烈抑制对红光的反应,但甘露醇有刺激作用。与分别施加两种刺激的效果相比,同时施加红光和生长素产生的反应大于两者相加的反应。
