Germination of Lactuca sativa L. was inhibited by mixtures of quinolizidine alkaloids. The alkaloid esters resulted in the strongest inhibition: 6 mM 13-tigloyloxylupanine inhibited germination by 100%, whereas the other lupin alkaloids, such as lupanine and sparteine, gave a 45 and 20% inhibition, respectively. Seedlings of Lupinus albus L., which are not affected by quinolizidine alkaloids, excrete lupanine and 13-tigloyloxylupanine into the surrounding medium by their roots. It is assumed that lupin alkaloids are potential compounds of plant-plant interaction (i.e. allelopathy) besides their role in plant-herbivore interrelations.
藜麦的萌发受到喹诺里西啶生物碱混合物的抑制。生物碱酯导致了最强的抑制作用：6 mM 13- tigloyloxylupanine 抑制发芽率达到 100%，而其他羽扇豆生物碱，如羽扇豆碱和斯帕丁，则分别抑制 45%和 20%。羽扇豆属植物的幼苗不受喹诺里西啶生物碱的影响，通过根部将羽扇豆碱和 13- tigloyloxylupanine 分泌到周围介质中。人们认为，羽扇豆生物碱除了在植物与草食动物的相互关系中起作用外，还是植物-植物相互作用（即化感作用）的潜在化合物。
