The hypothesis that ethylene regulates prostrate stem growth was investigated using stolons of strawberry clover (Trifolium fragiferum L. var. Salina). Stolons became erect when treated with ethylene or 2-chloroethylphosphonic acid. Curvature was visibly detectable 2 hours after ethylene treatment, and subsequent stem elongation was rapid. Indoleacetic acid application to prostrate stolons caused only a small transitory curvature persisting less than 48 hours. Indoleacetic acid-stimulated curvature was accompanied by an increase in ethylene evolution. When stolon curvature was induced by placing strawberry clover plants in darkness or by applying gibberellic acid, ethylene production did not parallel stolon curvature.
该假说认为乙烯调节脯氨酸茎生长使用匍匐茎的草莓三叶草 (三叶草根茎变种。撒利纳)。匍匐茎直立时用乙烯或 2-氯乙基膦酸处理。曲率明显可检测到 2 小时后乙烯处理后,随后茎伸长迅速。吲哚乙酸应用于匍匐茎只引起小的短暂曲率持续不到 48 小时。吲哚乙酸刺激的曲率伴随着乙烯释放的增加。当匍匐茎曲率通过将草莓三叶草植物放置在黑暗中或应用赤霉素诱导时,乙烯的产生并不与匍匐茎曲率平行。
