The experiment was conducted at an elevation of 1250 m above mean sea level at 30° 51’N latitude and 76° 11’E longitude at the experimental area of the Department of Fruit Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (Himachal Pradesh). The aim of present investigation is to study the effect of different growth regulators on physiological parameters in Chandler cultivar of strawberry in terms of stomatal resistance, transpiration rate, leaf photosynthetic rate and chlorophyll content. The experiment was conducted in randomized block design with three replications and 19 treatments viz., Pro.Ca @ 30,60,90 ppm; CPPU @ 2, 4, 6 ppm, GA3 @ 25, 50, 75 ppm, Ethephon @ 50, 100, 150 ppm, NAA @ 20, 30, 60 ppm, CPPU + GA3 @ 2+50, 4+50, 6+50 ppm and control. The growth regulators applied to the plants twenty days before flowering. The growth regulators exhibited significant effect on the physiological characters in strawberry plants. The CPPU treatment followed by GA3 alone and combined treatment resulted in maximum chlorophyll content, rate of photosynthesis, stomatal conductance, transpiration rate and minimum stomatal resistance.
