Effect of Plant Growth Regulators on Growth of Petunia (Petunia hybrida L.) var. Grandiflora Rose

The present investigation was conducted at the Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab in 2023 with ten treatments comprising of T1; Control, T2; GA3 (250 ppm), T3; GA3 (350 ppm), T4; GA3 (450 ppm). T5; CCC (450 ppm), T6; CCC (550 ppm), T7; CCC (650 ppm), T8; NAA (40 ppm), T9; NAA (50 ppm) and T 10; NAA (60 ppm) with three replications in randomized block design. The results revealed the maximum plant height (27.94 cm), plant spread (57.02 cm2), number of leaves/plant (651.04), number of branches/plant (21.96), Stem length (25.63), Leaf area (9.07 cm2) were in T3; GA3 at a rate of 350 ppm, while minimum plant height (19.05 cm) and Stem length (16.12 cm) was recorded in T6; CCC at a rate of 550 ppm and rest of the vegetative parameters was in T1; Control.
