Abstract: An experiment was conducted to study the effect of gibberellic acid on seedling growth in Kagzi lime at Regional Horticultural Research Station, Navsari Agricultural University, Navsari during the year 2016-17. The experiment was laid out in a Completely Randomized Design with factorial concept with sixteen treatments and three repetitions. Freshly extracted kagzi lime seeds (S1) and those stored for 15 days (S2) were soaked for 12 hours (D1) and 24 hours (D2) in aqueous solution of gibberellic acid at different concentrations i.e. 200 ppm (G1), 300 ppm (G2), 400 ppm (G3) and 500 ppm (G4). Freshly extracted kagzi lime seeds had significantly higher leaf area, total chlorophyll content, tap root length, tap root diameter, shoot dry weight and total dry weight. For all above mentioned characters, a soaking duration of 12 hours proved significantly better over 24 hours. GA3 at 500 ppm recorded significantly the highest leaf area, total chlorophyll content and tap root diameter. Further, for tap root length, shoot dry weight and total dry weight, significantly highest values were recorded under 400 ppm GA3 treatment. Shoot root dry weight ratio was significantly lower in case of freshly extracted seeds, GA3 at 200 ppm and a soaking duration of 12 hours when taken as separate factors. The interaction effect between storage treatments, different concentrations of GA3 and soaking duration was found non-significant for all parameters chosen in this study.
