Abstract

The present investigation “Response of foliar application of GA3 and paclobutrazol on flowering and vase life of Tuberose (Polianthes tuberosa L.)” was carried out was carried out in Horticulture Research Farm at the Department of Floriculture and Landscape Architecture, IGKV, Raipur, Chhattisgarh, India, 2017-18 and 2018-19. The experiment was laid out in Factorial Randomized Block Design with three replication comprising treatment combination of two PGRs (GA3 and Paclobutrazol) and two tuberose cultivars (Prajwal and Bidhan Ujjwal). Two PGR’s namely Gibberellins (GA3) and Paclobutrazol (PBZ) were taken as growth promoter and growth retardant, respectively. In this contest, an experiment was conducted to investigate the effect of different levels of growth promoter and retardant on growth, flowering and vase life of different cultivars of Tuberose. The result indicated that the vegetative growth, flowering and vase life were significantly influenced by different plant growth regulators and cultivars. The maximum plant height was recorded with cv. Prajwal (V1) as compared to cv. Bidhan Ujjwal (V2). While, minimum number days to first spike emergence (117.33 days), days to first flower opening (131.83 days) was recorded with cv. Bidhan Ujjwal. Among the growth regulators treatments GA3 150 ppm (30 and 50 DAP). However, maximum length of spike (94.72 cm), length of rachis (30.35 cm), length of florets (5.8 cm), diameter of florets (4.32 cm), Number of florets spike-1 (43.41) and Vase life (10.17 days) was recorded with cv. Prajwal. Among the growth regulators treatments GA3 150 ppm (30 and 50 DAP).
