Utilização de miniestacas de mangaba produzidas In Vivo e transplantadas in vitro para averiguação da adapatação e enraizamento em diferentes constituições de meio de cultura

Abstract

The Cerrado holds 5% of the planet's biodiversity and is considered the richest savanna in the world. In this complex Biome is the mangaba. Native fruit that produces nutritious fruits and appreciated by the population. Because the fruits are still collected in an extractive manner, it is necessary to study methodologies that address the vegetative propagation of this species for its introduction to cultivation and also its conservation. The objective of the work was to investigate the survival rates for adaptation, maintenance and rooting, as well as the types of contaminating agents, of mangaba mini cuttings in vitro in different culture media of seedlings produced in vivo. In vivo mincuttings of mangaba from genotypes of three varieties of mangabas (gardneri, cuyabensis and pubescens) were inoculated in a test tube containing 30 ml of MS culture medium with half the concentration of salts supplemented with vitamins in the medium. The rates of fungal agents, index of bacterial agents, index of roots, number of shoots, number of leaves, callus index at the base, and survival rate were evaluated at 5, 90 and 180 days after inoculation. The data were analyzed by obtaining the occurrence index of each event. The mini cuttings of the Cerrado mangaba genotypes showed promise in terms of in vitro adaptation and rooting.
