Chlorosubstituted-3-aroylflavones and chlorosubstituted-3-alkoylchromone were prepared by refluxing them separately with iodine crystal in ethanol. Initially chlorosubstituted-3-aroylflavanones and 3-alkoylchromanone have been prepared separately by the interaction of different aldehydes with 1(2-hydroxy-3,5-dichlorophenyl)-3-phenyl-1,3-propanedione. Constitutions of synthesized compounds have been confirmed on the basis of elemental analysis, molecular weight determination, UV-Visible, I.R. and 1H-NMR spectral data. The titled compounds were evaluated for their growth promoting activity on some flowering plants viz. Papaver rhoeas, Dianthus chinensis, Candy tuft, Calendula officinalise, Gladiola tristis, Gaillardia. %K Chlorosubstituted-3-aroylflavanones %K 3-alkoylchromanone %K 3-aroylflavones %K 3-alkoylchromone %K pyrazoles. %U http://www.irjponline.com/admin/php/uploads/1597_pdf.pdf
