Multiplicação in vitro da cultivar de batata ágata (Solanum tuberosum L.) E micropropagação

Abstract

The potato Solanum tuberosum L. culture finds favorable climatic conditions for its production in Brazil's southern region, representing an economically important product for the vegetable sector. The economic importance of potatoes justifies the need for studies that contribute to presenting techniques and knowledge about plant improvement in the area. The in vitro multiplication of the potato Ágata Variety (Solanum tuberosum L.) through micropropagation is an effective method for the large-scale production of pathogen-free and genetically uniform seedlings. This process uses plant tissue culture techniques, such as micropropagation, which involves cultivating plant cells in aseptic and controlled conditions. Through the formation of shoots and subsequent rooting in an appropriate culture medium, it is possible to obtain many healthy and genetically identical seedlings, contributing to the rapid expansion of potato production of the Ágata cultivar. Given these factors, the present work aimed to establish a protocol for the in vitro introduction and multiplication of potato explants cultivated agate in MS medium containing BenzylAminoPurine (BAP) concentrations and evaluated the number of shoots obtained at in the concentrations. At 0 (Control) concentrations, 1, 2, 3, 4, and 5 mg.L-1 of (BAP) BenzylAminoPurine. Data analysis was carried out quantitatively. The greatest effectiveness study occurred with the treatment process, subjected to concentrations of 1 and 2 mg.L-1 of BenzylAminoPurine (BAP), in which a percentage of 90% in the number of shoots obtained was obtained. According to the methodology developed in this study, it can be concluded that using (BAP) BenzylAminoPurina was responsive to the proposed objective.
