摘要: 【目的】筛选内蒙古巴彦淖尔市向日葵列当的诱捕作物。【方法】选取10种当地作物茼蒿、亚麻、青椒、洋葱、芹菜、胡萝卜、豌豆、蚕豆、西葫芦和甜瓜进行试验,采用营养钵培养法确定向日葵列当的寄主,然后用培养皿滤纸法明确各种作物根系分泌物对向日葵列当种子的刺激萌发作用。【结果】茼蒿和芹菜有向日葵列当的寄生,寄生率分别为12.821%和0.385%。10种供试作物均可以刺激向日葵列当种子的萌发,亚麻、胡萝卜、茼蒿向日葵列当种子发芽率在60.38%~67.50%;芹菜、青椒、豌豆、甜瓜在23.92%~32.60%;蚕豆为17.13%;西葫芦和洋葱的发芽率较低,分别仅为0.86%和5.33%。【结论】亚麻和胡萝卜不是向日葵列当的寄主,而且刺激向日葵列当种子的萌发,有作为向日葵列当诱捕作物的可能性。

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.
