摘要： 采用同质种植园实验研究南方菟丝子寄生对3种入侵植物一年蓬、土荆芥和三叶鬼针草生长的影响。结果表明：南方菟丝子寄生显著降低了一年蓬的根长，但对土荆芥与三叶鬼针草的根长无显著影响；南方菟丝子寄生显著降低了3种入侵植物的茎长与总长，尤其是一年蓬分别降低了67.4%和63.4%；且显著降低了3种入侵植物的根生物量、叶生物量、茎生物量、地上生物量和总生物量，其中影响最显著的是一年蓬，其根、茎、叶生物量分别减少达46.8%、81.7%和65.2%；南方菟丝子寄生可以显著提高3种入侵植物的根冠比。
Abstract: Effects of parasitic plant Cuscuta australis on the growth of three invasive plants, including Erigeron annuus, Chenopodium ambrosioides and Bidens pilosa, were investigated  in a common garden experiment The parasitic C. australis decreased significantly the root length of invasive E. annuus, but had no significant effect on that of invasive C. ambrosioides and B. pilosa. The parasitic C. australis decreased significantly the stem length and total length of three invasive plant species, in which the stem length and total length of E. annuus reduced up to 67.4% and 63.4%, respectively. The parasitic C. australis decreased significantly the root, leaf, stem, aboveground and total biomass of three invasive plants, in which the root, stem and leaf biomass of E. annuus reduced up to 46.8%, 81.7% and 65.2% respectively. The parasitic C. australis increased significantly the root / shoot ratio of three invasive plants.
