Allelopathic Stress Produced by Bitter Gourd (Momordica charantia L.)
The present study deals with in vitro effects of allelochemicals present in leaf and fruit leachate of Momordica charantia in vitro on plant growth and metabolism of Lycopersicon esculentum. Momordica was selected as a donor plant and tomato as recipient. Seeds of tomato were shown in pots and after...

| description | The present study deals with in vitro effects of allelochemicals present in leaf and fruit leachate of Momordica charantia in vitro on plant growth and metabolism of Lycopersicon esculentum. Momordica was selected as a donor plant and tomato as recipient. Seeds of tomato were shown in pots and after germination different concentrations viz. 25, 50, 75 and 100% of leaf and fruit leachates were applied as treatment. Twenty days old seedlings were harvested for biophysical and biochemical analyses. The root and shoot length, fresh and dry weight of the seedlings decreased in dose dependent manner. The reduction in pigment and protein contents and nitrate reductase activity was concentration dependent. Membrane leakage increased as the concentration of leachates increased. Activities of antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) activities significantly enhanced under allelopathic stress. Inhibition of various metabolic activities under allelopathic stress resulted in decreased plant growth and development. The fruit leachate of Momordica was more inhibitory than leaf leachate. |
