去除完整生菜幼苗的子叶可以延缓赤霉酸引起的下胚轴伸长。这种子叶切除的抑制效应可以通过将去胚轴的幼苗与从子叶或完整幼苗的热水提取物孵化来减轻。根据其红外光谱、核磁共振谱和质谱图，确定该活性成分为二氢松柏醇。
Removal of cotyledons from intact lettuce seedlings retarded hypocotyle elongation caused by gibberellic acid. This inhibitory effect of cotyledon excision was alleviated by incubating decotylized seedlings with a hot water extarct from excised cotyledons or intact seedlings. This active principle was identified as dihydroconiferyl alcohol on the basis of its IR, NMR and mass spectra.
