    Influencia del biocarbono sobre la respuesta morfofisiología de vitroplantas de Solanum tuberosum L. Var Superchola
    (2024-02) Mayorga Romero, Santiago Alberto; Munóz Espinosa, Manolo Sebastián
    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. Key words: Biochar, Vitroplants, Morphophysiology, Nutrients and Sustainable production.

    Efecto del biocarbono sobre la respuesta morfo-fisiológica de vitroplantas de Solanum tuberosum L. var. Cecilia en invernadero
    (2024-02) Del Castillo Bastidas Danny Fabián; Munóz Espinosa, Manolo Sebastián
    The objective of this research was to determine the effect of different proportions of biocarbon (Tectopore) and peat as a substrate, on the morpho-physiological response of Solanum tuberosum L. Var vitroplants. Cecilia under greenhouse conditions. For the investigation, a completely randomized design (DCA) was used with 10 repetitions per treatment, integrating one vitroplant for each experimental unit. The treatments that were applied were the following: T1 (100% Tectopore), T2 (80% Tectopore + 20% Peat), T3 (50% Tectopore + 50% Peat), T4 (20% Tectopore + 80% Peat) and T5 (100% Peat). The variables that were analyzed were the survival rate of the plants, the number of shoots present, the number and length of the roots, presence, length and thickness of nodes, as well as the distance between nodes, the leaf area of the leaves, plant height, fresh matter, dry matter, number of mini tubers, weight and diameter of these. Finally, an analysis of the macro- and micronutrient content of the plants was carried out. The research findings determined that the incorporation of biocarbon significantly improved the survival percentage of the vitroplants, as well as the morphological response and nutrient content in them. In particular, T5 demonstrated superior results in the variables studied. In addition to this, variations in micro- and macronutrient concentrations highlighted the positive influence of biochar on the nutritional status of plants, where specific treatments reflected a tendency to meet the needs of certain nutrients.
