Abstract
This article presents the effect of the concentration of gibberellin (GA3) and paclobutrazol on the growth and yield and produces sprouted tubers of Solanum tuberosum varieties of granola in vitro. The experimental design used was a randomized block design with two factors and two replications. The first factor is Gibberellins (g) with five level of factors there is, g0 = 0,0 mg L-1, g1 = 0.05 mg L-1, g2 = 0.1 mg L-1, g3 = 0.15 mg L-1, g4 = 0.2 mg L-1 and second factor Paclobutrazol (p) with five level of factors there is, p0 = 0,0 mg L-1, p1 = 2.5 mg L-1, p2 = 5 mg L-1, p3 = 7.5 mg L-1 and p4 = 10 mg L-1. The results showed that there was an interaction between the concentration of gibberellins and paclobutrazol on the growth and yield of potato plantlets of Solanum tuberosum L. varieties of granola in vitro and on observations of plant height but not on the number of leaves, number of shoots and micro bulbs. Gibberellins concentrations of 0.2 mg L-1 without Paclobutrazol good results for plant growth. Gibberellins concentrations 0.15 mg L-1 and paclobutrazol 5.0 mg L-1 can produce good sprouted tubers.
