THE EFFECT OF CONCENTRATION AND FREQUENCY OF GIBERELLINS ON THE GROWTH OF ARTEMISIA ANNUA Linn

Artemisia is one of the plants that can be used as an alternative medicine for malaria. The plant contains secondary metabolites in form artemisinin compounds function antimalarials. One efforts done to increase growth annua. by using a regulator gibberellins (GA3). Using Randomized Block Factorial Designs (RBFD) with first factor being concentration 50 mg.L-1 (K1), mg.L-1(K2), 150 (K3), 200 (K4). second has 3 frequencies, 1 time giving 7HSPT (F1), 2 times and 14HSPT (F2), 7HSPT, 30HSPT (F3). In addition, there were not given GA3 control (without treatment). Parameters observed height, leaf area, glandular trichome density, dry weight. results showed administration (GA3) different concentrations frequencies on weight A. annua had no significant effect. Plants have been able grow properly because provision active stimulates all tissues directly seeps through roots, stems leaves.
