A field experiment was carried out in the farmer field adjoining, RAK College of Agriculture, Sehore (Madhya Pradesh) during 2015 and 2016 to find out Physiological modification of Patharchur Coleus forskohlii (Willd) Briq as impact of Plant Growth Hormones. Field experiment consisting of Plant Growth Hormones MH @ (100 and 150 ppm), Cycocel @(500 and 1000 ppm), NAA @(50 and 100 ppm), GA3 @ (150 and 200 ppm) and water spray as control. Bjective of the study is to study the impact of plant growth Hormones on physiology of Coleus forskohlii (Willd) Briq. Physiological parameters like, Photosynthesis rate (µmol CO2 m-2 s-1), Stomatal conductance (mmol-1m2s-1), Transpiration rate (mmol H2O m-2 s-1), CO2 utilization (µmol CO2 mol-1) and H2O utilization (Kpa) by using IRGA and observations were recorded at 150 day after transplanting. Pooled data (2015 and 2016), 150 day after transplanting (DAT) revealed that application of Cycocel @1000 ppm resulted in increased Physiological parameters like, Photosynthesis rate (µmol CO2 m-2 s-1), Stomatal conductance (mmol-1m2s-1), Transpiration rate(mmol H2O m-2 s-1), CO2 utilization (µmol CO2 mol-1) and H2O utilization (Kpa), respectively (13.14, 14.56, 3.64, 13.53 and 0.458) followed by Cycocel @ 500 ppm (12.68, 13.64, 3.19, 13.38 and 0.447) as compare to control (10.63, 9.90, 2.22, 9.99 and 0.349).
