用乙烯或IAA处理3种水生植物（水鳖、二叶海葵和石龙毛茛）的枝条，研究其对枝条伸长的促进作用。2种激素的作用是相加的，乙烯生物合成抑制剂和银离子的实验表明，乙烯和IAA刺激生长的机制可能是不同的。水鳖属和毛茛属的叶盘从[14 C]甲硫氨酸合成[14 C]乙烯，但没有[14 C]乙烯由Regnellidium形成，表明存在乙烯生物合成的替代途径。
Elongation of the shoots of 3 aquatic plants (Hydrocharis morsus-ranae, Regnellidium diphyllum and Ranunculus sceleratus) is stimulated by treatment with ethylene or IAA. The effects of the 2 hormones are additive, and experiments with an ethylene biosynthesis inhibitor and Ag ions indicate that the mechanisms by which ethylene and IAA stimulate growth may be different. Hydrocharis and Ranunculus leaf discs synthesize [14C]ethylene from [14C]methionine, but no [14C]ethylene is formed by Regnellidium, suggesting the existence of an alternative pathway of ethylene biosynthesis in the fern.
