| A total number of 1000 seeds were randomly selected from each of the replicates, given that O. rufipogon usually produces limited fertile seeds. |
| All plants of O. parryi var. parryi sampled were solitary and all plants were shorter than one meter. |
| Experiments reported herein focused on cladodes of O. ficusindica and stem segments of O. parryi var. parryi. |
| The potential impact of the latter species on oilseed rape was recently reported in France, where this crop is heavily damaged by O. ramosa. |
| In vitro infection of host roots by differentiated calli of the parasitic plant Orobanche was also achieved in O. ramosa. |
| This has already been reported in O. foetida on faba bean and winter chickpea in North Africa. |
