Allelopathic effects of Hyptis suaveolens L. on growth and metabolism of pea seedlings
Journal Title: Scientia Agriculturae - Year 2015, Vol 12, Issue 3
Abstract
The present study deals with the allelopathic stress caused by allelochemicals present in leachate of Hyptis suaveolens L. on growth and metabolism of pea seedlings. Seeds were soaked in distilled water for 3 hours. Five Seeds of Pisum sativum were sown in each pot filled with acid washed sand. Pots were moistened exogenously with different concentrations of leachate viz. 25, 50, 75 and 100% respectively. Twenty days old seedlings were taken for biophysical and biochemical parameters Root length and shoot length, fresh weight and dry weight of pea seedlings decreased in dose dependent manner. Pigment content, protein, sugar and activities of nitrate reductase were decline. Activities of enzymes viz. superoxide dismutase, catalase and peroxidase increased under allelopathic stress caused by the allelochemicals present in the leachate of donor plant. Increases in lipid peroxidation were observed in terms of malondialdehyde (MDA) content. Allelopathic stress influence several metabolic activities of plant which lead to inhibition in growth and metabolism of recipient plant.
