Effect of hydrogen sulphide on growth and some biochemical changes in rocket and radish plants

ABSTRACT

These experiments were a field trial which has been carried out to show the effect of H2S fumigation [0, 50 and 100 ppm] on growth and some biochemical changes in rocket and radish plants. Results showed that during the growth periods [3-6 weeks] of both rocket and radish plants, all growth parameters decreased as affected by H2S. Application of H2S decreased most of the N fractions, accumulation of sugars and biosynthesis of polysaccharides. H2S greatly reduced the activities of peroxidase, nitrate-reductase and glutamate dehydrogenase enzymes. Also H2S showed varied effects on the different amino acids
