| Abstract:
Seed fortification treatment increases conversion of reserve nutritional material into mobile compounds and also invigourates the seeds by altering their physiological and biochemical nature resulting in better emergence and establishment under field conditions. To impose fortification, cluster bean seeds were soaked in equal volume of freshly prepared leaf extracts viz., Prosopis juliflora, Tamarindus indica, Moringa oleifera, Hibiscus sabdariffa, Pongamia pinnata and Albizza amara at 1% concentration for 3 h (with water soaking as control) and then dried back to original moisture content. Seeds fortified with P. juliflora, P. pinnata and A. amara leaf extracts recorded higher seed germination vigour and field emergence than other leaf extracts and control treatment. The improvement of field emergence by botanical leaf extracts could be ascribed to the activation of cells that resulted in the enhancement of mitochondrial activity leading to the formation of high energy compounds and vital biomolecules which were made available during the early phase of germination. | |
