Intraspecific Physiological Variants of Striga hermonthica
Experimental Agriculture, 1981SUMMARYPreliminary evidence is presented in this study for the existence of (1) intraspecific physiological variants of Striga hermonthica, with Gabob population as the most responsive strain to a range of Sorghum bicolor cultivars, and (2) a local Sudanese sorghum cultivar called Tetron with broad-spectrum resistance to striga.

The dynamics of strigolactone perception in Striga hermonthica: a working hypothesis
Journal of Experimental Botany, 2018Plant-derived strigolactones have diverse functions at ecological scale, including effects upon the growth of plants themselves. The parasitic plants from the family Orobanchaceae interfere with the ecological and hormonal functions of strigolactones to generate unique germination abilities based on the sensing of host-derived strigolactones.

Effect of fungal toxins on germination of Striga hermonthica seeds
Weed Research, 1999Fourteen fungal toxins were assayed in vitro to evaluate their effect on seed germination of the parasitic weed Striga hermonthica. Among them, T‐2 toxin proved to be the most active, being able to inhibit 100% seed germination at 10−5 M, and being still active when tested at a concentration of 10−7 M (19% inhibition).

MECHANISMS FAVOURING OUTBREEDING IN STRIGA HERMONTHICA [SCROPHULARIACEAE]
New Phytologist, 1984SummarySelf‐incompatibility has been demonstrated in two samples of the parasitic flowering plant, Striga hermonthica, originating from Upper Volta and Sudan. Compatibility was determined by fluorescence microscopy of stigmatic preparations following controlled pollinations.

Carotenoid inhibitors reduce strigolactone production and Striga hermonthica infection in rice
Archives of Biochemistry and Biophysics, 2010The strigolactones are internal and rhizosphere signalling molecules in plants that are biosynthesised through carotenoid cleavage. They are secreted by host roots into the rhizosphere where they signal host-presence to the symbiotic arbuscular mycrorrhizal (AM) fungi and the parasitic plants of the Orobanche, Phelipanche and Striga genera.

THE PARASITISM OF STRIGA HERMONTHICA BENTH. ON LEGUMINOUS PLANTS
Annals of Applied Biology, 1947Pot experiments at the Gezira Research Farm showed that Striga hermonthica Benth. is not confined to the Gramineae but can also parasitize groundnuts, cowpea, dolichos bean and soya bean, causing a loss in yield in all but the last‐named. The Striga plants developing on the roots of these hosts were small, apparently ill‐nourished and did not grow more

Natural Product Research, 2003
Treatment of conditioned seeds of four isolates of Striga hermonthica and one isolate of Striga aspera with various concentrations of the ethylene precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), caused complex stimulation of germination patterns.

Striga hermonthica on sorghum in East Africa
The Journal of Agricultural Science, 1965Two sorghum varieties, Dobbs and Bukura Mahemba, were grown in Tanganyika over a wide range of sites, seasons and naturally occurring levels of Striga infestation. Dobbs showed good Striga resistance relative to Bukura Mahemba: In Dobbs there were 9% of the number of witchweed plants above ground as against Bukura Mahemba. (3200 to 37,200 Striga plants
