ABSTRACT
Two varieties of pearl millet viz., 7042S and IP18294, highly susceptible and highly resistant to virulent pathotype 1 of S. graminicola, and a virulent pathotype 1 of S. graminicola was used in the present investigation. The commonly available herbs, viz., Alternaris sessilus, Curcuma longa, Cuminum cyminum, Cinnamon camphora and Cucurbita maxima were homogenised with distilled water, acetone, chloroform and methanol at 4oC and the extract was used as inducer of resistance. After preliminary studies like seedling vigor, vegetative and reproductive growth parameters, selected inducer in solvent was used to induce the resistance in plants by seed treatment. In the experimental sets, the biochemical parameters like qualitative analysis of peroxidase, superoxide dismutase and esterases were tested. The test results clearly indicated that Cucurbita extract induced resistance. Experimental sets showed remarkable variation when compared to control sets.
Keywords: Induced resistance, Pennisetum glaucum, Sclerospora graminicola, Peroxidase, SOD, Esterase.
