Abstract: An experiment on “Flower quality in Jasminum sambac (L.) as influenced by pruning and plant growth retardant spray” was carried out at the Department of Floriculture and Landscaping, Tamil Nadu Agricultural University, Coimbatore to find out the ideal pruning time, growth retardants and also its concentration to improve the flower quality parameters of Jasminum sambac (L.) during off-season flowering. The flower quality parameters viz., total length of flower bud (2.64 and 2.85 cm), length of flower bud without corolla tube (1.37 and 1.47 cm), corolla tube length (1.27 and 1.38 cm) and diameter of flower bud (0.87 and 1.00 cm) were influenced significantly in plants pruned during last week of September along with foliar spray of MC @ 150 ppm. There is no interaction effect between pruning and growth retardant spray for these parameters. The biochemical parameters viz., chlorophyll index (48.42, 52.49 and 59.77 SPAD value), total phenol content (1.77, 2.11 and 2.48 mg g-1) and soluble protein (13.49, 14.55 and 16.95 mg g-1) were significantly influenced by pruning during last week of September along with foliar spray of MC @ 150 ppm. The interaction effect was also significantly influenced in plants pruned during last week of September along with foliar spray of MC @ 150 ppm against the flowering parameters.
