Abstract

A study on the effect of gibberellic acid (GA3) on growth of late planting Tioga strawberry was undertaken at Phetchaboon Research Station. Amphur Kaokor, Phetchaboon Province. Two applications of 4 levels of GA3 viz. 50, 100, 150 and 200 ppm, at 7-day intervals increased petiole length where as leaf size, leaf number and branch crown were not significantly different. Each treatment of GA3 significantly increased the runner production from 0.05 runner per plant in control to 2.4 runners per plant in GA3 200 ppm treated plant. In contrast, fruit production decreased when higher levels of GA3 were applied.
