Abstract: 【Objective】To screen the trap crops of sunflower broomrape(Orobanche cumana Wallr.)in Bayannur City,Inner Mongolia.【Methods】The experiment included ten local crops:chrysanthemum,flax,green pepper,onion,celery,carrot,pea,broad bean,zucchini and melon. Plants grown on culture medium were used to determine the host of sunflower broomrape. Petri dish with filter paper was used to investigate the stimulating effect of various crop root exudates on sunflower broomrape seeds germination. 【Results】The parasitism of sunflower broomrape were found in chrysanthemum and celery,with parasitism rates of 12.821% and 0.385%,respectively. All ten crops could stimulate sunflower broomrape seeds germination. The germination rate of sunflower broomrape seeds on flax,carrot,and chrysanthemum was between 60.38% to 97.50%,and 23.92% to 32.60 on celery,green pepper,pea,and melon,17.13% on broad bean. The germination rate on zucchini and onion were only 0.86% and 5.33% respectively.【Conclusion】Flax and carrot are not the hosts of sunflower broomrape. However they do promote the germination of sunflower broomrape seeds,which might have the potential to be used as trap crops of sunflower broomrape.
