(±)-Jasmonic acid is a plant growth regulator and a derivative of α-linolenic acid.[1] It decreases chlorophyll levels in green and etiolated barley leaf segments when used at concentrations of 10 and 50 µM.[2] (±)-Jasmonic acid (10-1,000 µM) inhibits elongation of rice seedlings.[3] It increases germination of S. hermonthica seeds by 26% when used at a concentration of 1,000 µM.[4]
(±)-茉莉酸是一种植物生长调节剂，是α-亚麻酸的衍生物。[1] 当浓度为10和50 µM时，它会降低绿色和伸长的大麦叶片中的叶绿素水平。[2] (±)-茉莉酸(10-1,000 µM)抑制水稻幼苗的伸长。[3] 当浓度为1,000 µM时，它增加了草寄生种子的发芽率26%。[4]
