EFFECT OF GROWTH REGULATORS FOR in vitro PROPAGATION OF THE MALANGA (Xanthosomasagittifolium (L) SCHOTT)

Abstract

In this work they tested several concentrations and combinations of regulators of growth so much for the establishment and in vitro multiplication of yolks, since for the enraizamiento and acclimatization Ex Vitro of explantes of Malanga (Xantomona sagittifolium (L) Schott.). The 68.75% of the yolks established in a way of culture shaped by the totality of you them go out of the MS suplement with 0.1mg L^-1 of BAP they survived without contaminating. At best, the outbreaks multiplied 1.91 times and grew up to 4.86 cm in the first subculture that used the totality of you them go out of the MS suplement with 3 mg L^-1 BAP + 1.5 mg L^-1 AIA. In the phase of enraizamiento and acclimatization they survived 75% of the explantes witness, in spite of the fact that they developed the roots more long (6.92 cm). With the treatment containing 500 mg kg^-1 both of ANA and of AIB; they survived 80% of the outbreaks, which developed in average 9.14 roots of 5.9 cm c/u. The mentioned treatments, with the concentrations of auxina go down, they presented the best results for the enraizamiento and acclimatization of the vitroplants.
