Abstract
Pinus taeda stands for productivity and quality of its timber [1]. Researches using biotechnology are of great importance and have been applied to the improvement of its timber and plantation [2]. The main method of Pinus propagation is by seeds, once the minicuttings depends on the season of the year or depends of juvenile material [3-5]. Thus, researches on micropropagation of Pinus taeda are currently a priority in Brazil [6]. Micropropagation is the best method for mass production of superior genotypes and represents a strategy for tree improvement and capture of genetic gains [7]. Studies on Pinus taeda micropropagation by axillary bud proliferation are quite few. The purpose of this study was to develop a protocol for micropropagation of this species from juvenile material.

The main method of Pinus propagation is by seeds, once the minicuttings depends on the season of the year or depends of juvenile material [3,4,5]
For the induction of roots, we tested the effect of double-layer medium, with semi-solid phase consisting of agar and water or GDm/2 [12] medium and the liquid phase containing water or GDm/2 medium
