Item 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 SebastiánThe 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.
