A study was conducted to evaluate the effects of plant growth regulators, specifically benzyladenine (BAP) and kinetin (KIN), in combination with auxins (IAA and NAA), on the micropropagation of potato (Solanum tuberosum L.) cv. Burin. The experiment used a Completely Randomized Design (CRD), and data were analyzed using ANOVA followed by Tukey’s Honestly Significant Difference (HSD) test (P ≤ 0.05). The results showed that 0.5 mg/L BAP achieved the highest shoot induction rate (70 %), whereas 1.0 mg/L BAP significantly increased the number of branches (3.1 branches/plant). The maximum branch length (3.5 cm) was also observed at 0.5 mg/L BAP. In the multiplication stage, increasing KIN concentration in conjunction with 0.5 mg/L NAA gradually enhanced branch length, reaching a maximum of 13.1 cm at 8.0 mg/L KIN. Regarding microtubers induction, the combination of 80 g/L sucrose with 2.0 mg/L each of BAP and KIN produced the highest number of tubers (ten per jar) and significantly increased average tuber weight to 1.07 g, when compared to the 40 g/L sucrose treatment. These findings show that the synergism between sucrose levels and growth regulators critically governs shoot development and tuberization. Optimal tuber production in cv. Burin is achieved by supplementing the medium with 80 g/L sucrose and 2.0 mg/L BAP + KIN. This study provides a refined protocol for enhancing potato micropropagation efficiency in commercial breeding programs.

Se realizó un estudio para evaluar los efectos de los reguladores del crecimiento vegetal, donde se incluyó bencil adenina (BAP) y kinetina (KIN), en combinación con auxinas, como IAA y NAA, en la micropropagación de papa. El experimento se estableció con un Diseño Completamente al Azar (DCA) y los datos se analizaron mediante ANOVA y la prueba de Tukey (p ≤ 0.05). De acuerdo con los resultados, 0.5 mg/L de BAP resultó en la tasa más alta de formación de ramas (70 %), mientras que 1.0 mg/L de BAP resultó en un aumento en el número de ramas (3.1 ramas/planta). La longitud de las ramas fue mayor con 0.5 mg/L de BAP (3.5 cm). Junto con NAA, KIN aumentó gradualmente la longitud de las ramas, alcanzando 13.1 cm con 8.0 mg/L. En cuanto a la formación de tubérculos, 80 g/L de sacarosa con 2.0 mg/L de BAP + KIN produjeron el mayor número de tubérculos por frasco (10 tubérculos) y aumentaron significativamente el peso del tubérculo a 1.07 g en comparación con 40 g/L. Es evidente que el equilibrio entre la sacarosa y los reguladores de crecimiento impacta directamente en el desarrollo de brotes y tubérculos. La mayor producción de tubérculos se logra cuando se agregan 80 g/L de sacarosa a 2.0 mg/L de BAP + KIN. Se ha hecho una contribución significativa para mejorar las técnicas de micropropagación de papa para programas de mejoramiento comercial.
