Application of bioproducts in vitroplants of banana (Musa acuminata clone "Gran enano) in the acclimatization phase

Abstract

The research was carried out in a shade house with a mesh roof and walls belonging to the Center for Agricultural Technology Studies (CETA), attached to the Agroforestry Faculty in the municipality "El Salvador" from March to June 2017. The objective was to evaluate the response of banana vitroplants (Musa acuminata Colla subgroup Cavendish, “Gran enano” clone) by in vitro culture through the application of bioproducts in the acclimatization phase. They were planted in polyethylene bags 20 cm high and 10 cm wide in a substrate composed of soil and organic matter from sheep manure in a 3:1 ratio. The treatments were distributed in three replicates and four treatments in a completely randomized design, which consisted of a control treatment and the application of 2.5; 3.5 and 5mL L-1 of Spiruvinas combined with the Rhizophagus irregularis strain of AMF. The height, number of leaves, diameter of the pseudostem, number of roots, dry and fresh weight of the root at 25, 35 and 55 days were evaluated. It was observed that the treatments with Spiruvinas surpassed the control treatment in the evaluated variables, highlighting the dose of 3.5mL L-1 combined with the strain of arbuscular mycorrhizal fungi (AMF), which induced greater growth and development of vitroplants of banana compared to the other treatments. A higher quality of the acclimatized plants was determined in less time possible.
