Water extracts from the carrot seed (Daucus carota L.) var. Perfekcja exhibit plant growth inhibitory properties against cress, cucumber, onion and carrot in a dose-dependant manner. This property results from the action of low-and high-molecular components of the extract. The low-molecular component was identified as crotonic acid ((E)-2-butenoic acid). Its presence was also confirmed in other late varieties of carrot. The determined strong herbicidal properties of crotonic acid and its availability after release to soil combined with its high level in seeds suggest that it might be considered as an allelopathic and autotoxic factor in the seeds.
胡萝卜种子（Daucus carota L.）品种Perfekcja的水提取物对水芹、黄瓜、洋葱和胡萝卜表现出剂量依赖性的植物生长抑制特性。这种特性源于提取物中低分子和高分子成分的作用。低分子成分被鉴定为巴豆酸（(E)-2-丁烯酸）。在其他晚熟胡萝卜品种中也证实了其存在。所测定的巴豆酸的强除草特性及其释放到土壤后可利用性，再加上其在种子中的高含量，表明它可能被视为种子中的化感和自毒因子。
