Effectof fluorine compounds onto germination of seeds ofagriculturalcrops

Abstract

The author investigates the action of various concentrations of sodium fluoride, potassium fluoride and ammonium fluorideon theenergy of germination and viability of seeds of field pea, corn, barley, andonion. Species-specific stimulations of the process of germination of onion seeds by the minimal concentration of sodium fluoride (5 mgF-/l) have beene stablished, where as higherc on centrations off luorine compounds (10, 50, 80 and100 mgofF-/l) suppressed this processin the series of peacornbarley.
