The present investigation was carried out at Horticultural Research Station, Mandouri, BCKV, Mohanpur, West Bengal, India to study the influence of plant growth regulators on growth, flowering, yield and quality of Hybrid Tea rose cv. Bugatti. The experimental results revealed that GA3 (Gibberellic acid) at 200 ppm + BA (Benzyladenine) at 100 ppm (T6) showed maximum plant height (72.50 cm), leaf area (69.39 cm2), pedicel length (6.07 cm), least weight loss percentage in vase solution. The maximum primary (3.84) and secondary shoots (14.33), stalk diameter (0.62 cm), pedicel diameter (0.70 cm), total number of flowers per plot (16.67), vase life (9.03 days), total anthocyanin (42.76 mg/ 100 g) and chlorophyll content (11.13 mg/g) were obtained in BA at 200 ppm (T4). The treatment BA at 100 ppm (T3) showed maximum spread, bud diameter at tight bud stage, flower diameter at cup shape and stalk weight. The maximum shoot length and stalk length were under BA at 200 ppm + GA3 at 100 ppm (T5). The earliness of flowering and flower diameter increase per cent in vase solution was maximum under GA3 at 100 ppm (T1). The highest values on vegetative and flowering parameters as well as flower quality were achieved in BA at 200 ppm as compared to other treatments.
