ABSTRACT
Effect of Solanum forskalii Dunal on seed germination and early seedling growth of three test plants namely mustard, wheat and corn was examined. Aqueous extract of S. forskalii at different concentrations (25, 50, 75 and 100% stock solution) inhibited the germination, root and shoot growth of all the three test species. Germination and growth were reduced by the shoot extract in the order: mustard > corn > wheat. Decaying shoot of S. forskalii in sandy loam at 5, 10 and 20 g/kg soil substantially inhibited germination and seedling growth of bulrush millet (Pennisetum americanum) at all the dosages. Bioassay of the ether extract of S. forskalii revealed four zones of inhibition at Rf values 0.1-0.2,0.2-0.3, 0.8- 0.9 and 0.9-1.0. Chromatography for the phenolics revealed the presence of nine phenolic compounds: salicylic acid, vanillic acid, syringic acid, catechol, gentisic acid, 4-methylresorcinol, protocatechuic acid, pyrogallol and an unknown.
