Influencia del biocarbono sobre la respuesta morfofisiología de vitroplantas de Solanum tuberosum L. Var Superchola

Abstract

The study addresses the influence of biocarbon in vitroplants of Solanum tuberosum L. Var Superchola under greenhouse conditions. In a global context of agricultural challenges, biocarbon is presented as a sustainable strategy to improve productivity and reduce greenhouse gas emissions. Biocarbon, derived from organic residues such as teak, improves soil fertility, increases moisture retention and increases cation exchange capacity. The study focuses on the Superchola variety, important in the Ecuadorian diet and economy, with the objective of evaluating how vitroplants respond to teak biocarbon substrates. The research was carried out at the Technical University of Ambato. Based on the results obtained, they revealed that the combination of biocarbon and peat affects the morphophysiological response of vitroplants. Mixtures with a lower proportion of biocarbon showed better results, with Tb1-Bc0 (100% blond peat + 0% biocarbon) standing out. In addition, it was observed that high amounts of biocarbon negatively affect plant growth. Nutrient extraction varied according to substrate combinations, being advisable to optimize the choice of mixtures to promote a favorable morphophysiological response. The importance of monitoring biocarbon use is emphasized and further investigation of its interaction with plant morphology and nutrient extraction is suggested. As we have seen, the study offers guidelines to improve the sustainable production of potatoes, a vital species for food and economy in Ecuador, emphasizing the need for a careful and strategic management of biocarbon.
