The effects of a plant regulator were studied for rangpur lime seedlings sprayed at 14-day intervals, from the 70th day until the 210th. The seedlings were sprayed with: T1 = 0; T2 = 25; T3 = 50; T4 = 100; T5 = 150 ppm of gibberellic acid. The applications of gibberellic acid on the seedlings of rangpur lime rootstocks resulted in significant increases in plant height (T5 = 150 ppm) and stem diameter (T2 = 25 ppm and T3 = 50 ppm). The seedlings reached the buddable size in shorter time through the positive effects of the plant regulator. The stem diameter was higher with gibberellic acid at concentrations of 25 and 50 ppm. Shortening this time would benefit nurserymen by reducing various production inputs and costs.
