ABSTRACT
This study was carried out to determination of GA3 (Gibberellic acid) and IAA (Indole-3-Acetic Acid) on flower and bulb yield of tulip (Tulipa gesneriana Var. Cassini). 50 (G1), 100 (G2), 250 (G3) and 500 (G4) ppm concentrations of Gibberellic Acid (GA3) and 500 (A1), 1000 (A2), 2500 (A3) and 5000 (A4) ppm concentrations of Indole-3-Acidic Acid (IAA) were applied. According to the results G3 gave highest number of earlier flower (9.10 flower m-2), but lowest number of earlier flower obtained from A4 (5.56 flower m-2). The bulb yield and bulb weight were highest on A4 (671.7 g m-2 and 6.25 g) and G3 caused reduction on bulb yield and bulb weight (494.2 g m-2 and 4.99 g). These results clearly indicated that GA3 application stimulated flowering. But high dose of IAA application was detrimental, on the contrary bulb yield and individual bulb weight were increased. Stalk elongation was not affected significantly by GA3 and IAA applications.
