e1“The effect of nutrients (nitrate, ammonium, urea, phosphate and potassium) on the production and/or exudation of germination stimulants for clover broomrape (Orobanche minor Sm.), a root holoparasite, by its host red clover (Trifolium pratense L.) was examined using hydroponically grown material”
e2“Potassium (K2SO4) concentrations up to 100 mg l-1 (based on K) did not affect the production of germination stimulants by red clover”

- Intervention effect Phosphate at concentrations as low as 1 mg l-1 strongly inhibited germination stimulant production by red clover
- Intervention effect Nitrate markedly promoted germination stimulant production by red clover in a dose-dependent manner from 2 to 50 mg l-1
- Intervention effect Ammonium was inhibitory to germination stimulant production by red clover at concentrations above 2 mg l-1
- Intervention effect Urea was promotive of germination stimulant production by red clover at concentrations above 2 mg l-1
