Protocol otimization for micropropagation of 'Roxo de Valinhos' fig tree

Effects of different concentration of sucrose on Wood Plant Medium -WPM and variations on number of bud/plantlets with different doses of kinetin were evaluated on this research. The experiments were carried out in the Tissue Culture Laboratory at Federal University of Lavras, using plantlets which was already established in vitro. The experimental design adopted was the complete randomized in factorial scheme 5 x 4. The results revealed that better sprouts multiplication of ‘Roxo de Valinhos' fig plants occurred in WPM medium, 100% salts, added with 10gL-1 of sucrose and the sprout elongation in WPM medium without kinetin taking explants within one or two buds. Adding 0.5mgL-1 of kinetin and taking explants with tree buds promoted larger sprouts number.
