Kinetin in concentrations of 10(-8) to 10(-4)m, stimulated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisum sativum L. var. Alaska). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings.Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhancing effect of IAA.Gibberellic acid had no effect on ethylene production by pea seedlings during the first 6 days of growth. Ethylene and gibberellic acid are antagonistic in their effects on growth of the seedlings; ethylene interfered severely with the action of gibberellic acid but did not completely suppress it.The inhibitors cycloheximide, cupferron, and N-ethylmaleimide, caused considerable inhibition of kinetin-induced ethylene production but were much less effective in the endogenous ethylene-forming system.
在 10(-8) 到 10(-4)m 的浓度下，激动素刺激了 3 天和 4 天龄的白化豌豆（Pisum sativum L. var. Alaska）幼苗的乙烯生成。其他物种的幼苗也有类似的反应。对激动素的反应取决于幼苗的年龄。单独的激动素不会影响 6 天大的茎段中的乙烯生成，但它大大增加了 IAA 的增强效果。在生长的头 6 天，赤霉素对豌豆幼苗的乙烯生成没有影响。乙烯和赤霉素在幼苗生长中的作用是拮抗的；乙烯严重干扰赤霉素的作用，但不能完全抑制它。抑制剂环己酰亚胺、铜铁试剂和 N-乙基马来酰亚胺，对激动素诱导的乙烯生成有相当大的抑制作用，但对内源性乙烯形成系统的抑制作用要小得多。
