Abstract
El objetivo del estudio fue evaluar el efecto de bioestimulantes en la producción de semillas prebásicas de papa (Solanum goniocalyx), a partir de plántulas cultivadas in vitro en módulos tipo fitotoldo, en condiciones altoandinas de Huánuco, Perú. Se evaluaron tres tipos de bioestimulantes: Bio auxinas + Aminoácidos (T2), AATC+ Ácido fólico + Aminoácido (T3) y Aminoácidos + Nitrógenos + Fitohormona (T4), dentro de un diseño experimental de bloques completos al azar que incluía 4 tratamientos y 12 unidades experimentales. Entre los hallazgos obtenidos, el T3 (AATC + ácido fólico + aminoácidos) generó mejores resultados. Este tratamiento produjo el mayor número de tallos por planta (2,85), mayor altura (55,26 cm), mayor número de tubérculos (13,53 por planta) y los mayores pesos en tuberculillos de primera (49,63 g) y segunda categoría (73,57 g). Los resultados demuestran que el uso de bioestimulantes, especialmente T3, mejora significativamente la producción de semillas prebásicas en ambientes andinos, representando una alternativa viable para pequeños agricultores que buscan obtener semillas de alta calidad y libres de patógenos.
The objective of this study was to evaluate the effect of biostimulants on the production of pre-basic potato (Solanum goniocalyx) seeds from seedlings grown in vitro in phyto-tent modules under high Andean conditions in Huánuco, Peru. Three types of biostimulants were evaluated: Bio auxins + Amino acids (T2), AATC + Folic acid + Amino acid (T3), and Amino acids + Nitrogens + Phytohormone (T4), within a randomized complete block experimental design that included 4 treatments and 12 experimental units. Among the findings obtained, T3 (AATC + folic acid + amino acids) generated the best results. This treatment produced the highest number of stems per plant (2.85), the greatest height (55.26 cm), the highest number of tubers (13.53 per plant), and the highest weights of first (49.63 g) and second category (73.57 g) tubers. The results demonstrate that the use of biostimulants, especially T3, significantly improves prebasic seed production in Andean environments, representing a viable alternative for small farmers seeking high-quality, pathogen-free seeds.
