Tipo de explante e diferentes concentrações de sais em meio de cultura MS no estabelecimento in vitro de Aniba canelilla

Abstract

The peel - precious ( Aniba canelilla ) is a plant species native to the Amazon region , with economic potential in silvicultural terms , the production of perfumes and cosmetics . However , one limitation to the domestication of the species is the absence of propagation methods . The objective of this study was to evaluate the effect of explant type and different salt concentrations of MS medium in their establishment in vitro . Shoot tips ( 1.5 cm ) and nodal segments were used with two gems, isolated from bark - precious seedlings maintained in the greenhouse . The treatments consisted of two types of explants and six concentrations of salts in MS medium plus 15 or 30 g L- 1 sucrose and disinfectants . It was found that the nodal segment is less sensitive to treatments performed disinfestation and decontamination showed higher successful in survival and in vitro establishment of shell - precious.
