An experiment was conducted to evaluate the effect of plant growth regulators on growth, yield, and flower quality of gerbera (Gerbera jamesonii L.) cv. Goliath under naturally ventilated shade house in the Floriculture area, Department of Horticulture, Faculty of Agriculture, Annamalai University, Tamil Nadu during October 2014 to march 2015. The experiment was laid out in Randomized Block Design with three replications and nine treatments. In this study gerbera plants were sprayed with 100, 150, 200, 250 ppm of GA and 100, 150, 200, 250 ppm of NAA along with control (water spray). The results of five months experimentation revealed that maximum plant height (43.24 cm), number of leaves per plant (25.29), plant spread (51.74 cm), days to first flower bud emergence (41.03 days), flower diameter (13.81 cm), stalk length (46.92 cm), stalk girth (1.92 cm) and number of flowers per plant (9.46) were produced in treatment (T4) GA at 250ppm. Maximum vase life of flower with 13.19 days was recorded in the treatment (T4) GA3 at 250 ppm. T4 was found to be the best treatment for good vegetative growth as well as for quality flowers.
