Abstract: Plants of an early flowering Antirrhinum cultivar 'Chimes White' were pinched at 4, 5, 6, and 7 leaf-pair stage to observe the effects on flowering time and plant quality. Though control plants flowered earlier (81 days) than the pinched ones, they produced less number of flower buds. Flower time and rate of progress to flowering in pinched plants increased linearly and significantly. The quality of pinched plants regarding branch numbers, leaf area, plant height, plant fresh weight etc. was significantly improved in all treatments. Many plant growth parameters were successfully fitted by the second degree polynomial model whereas linear model indicated a good fit in reproductive development.
