Of the various factors regulations plantgrowth and developmental processes intrinsic factors play a significant role. Plant hormones are chemicals that regulateplant growth. These occur in extremely low concentrations and influence all developmental and physiological processesin plants. The effect of different concentrations of GA3 on seed germination of Tithonia rotundifolia Blake was studied.The maximum percentage of seed germination was at 500 ppm GA3
