Abstract: 

Broomrape (Orobanche sp.) is a phanerogamich holoparasitic weed that causes considerable yield losses in some of important crops family including Asteraceae, Solanaceae, Cucurbitaceae. In this research, the effects of GR60 (seed germination stimulator), scarification and spore suspension Fusarium oxysporum (biocontrol agent) on O. cernua seed germination were investigated. At the first, the effects of various concentration of GR60 (0, 1, 2 and 5 ppm) on O. cernua seed germination was studied. Results showed that treating the seeds with 2ppm of GR60 resulted in the highest seed germination (50%), whereas 5 ppm of GR60 caused the least seed germination (3-4%). Scarification treatment did not have a significant effect on O. cernua seed germination. The effects of F. oxysporum suspension (1×10 6 spores/ml) on O. cernua seeds was also investigated. Results showed that F. oxysporum suspension caused significant reduction in O. cernua seed germination (60%). Application of both methods, the synthetic compounds such as GR60 for stimulating O. cernua seed germination in absence of host plant and biocontrol agents such as some isolate of F. oxysporum, can be used for reduction of the broomrape seed bank and control of this parasitic weed.
