Abstract: A field experiment was conducted at the Department of Floriculture and Landscaping, Tamil Nadu Agricultural University, Coimbatore during 2015 – 2016 to study the effect of pruning and paclobutrazol application on physiological and flowering characters of Jasminum sambac during off season (Oct.–Feb.). The experiment was laid out in Randomized Block Design (RBD) with 10 treatment combinations. Among the treatment combinations the plants treated with soil drenching of paclobutrazol at 300ppm as significantly increased physiological parameters viz., chlorophyll a (0.77 mg g-1), chlorophyll b (0.49 mg g-1) and total chlorophyll (1.33 mg g-1), total phenol content (4.65 mg g-1), IAA oxidase activity (12.35µg of unoxidised auxing-1 h-1), soluble protein (16.05 mg g-1), specific leaf weight (0.0114 mg cm 2) and flowering parameters viz., diameter of the flower buds (7.98 mm), corolla tube length (11.08 cm) and weight of hundred flower buds (20.96 g) (Feb.) in Jasminum sambac.
