Some morphologic and physiologic responses of some plants to hydrogen sulphide

ABSTRACT

Experiments were conducted with rocket, radish and tomato seedlings to determine the effect of H[2]S at different concentrations on the growth and some biochemical changes. H[2]S induced significant inhibitory effect on radical and plumule elongation, photosynthetic activities, accumulation of soluble sugars and biosynthesis of polysaccharides. The degrees of inhibition was a function of both concentration and duration of treatment
