Abstract
El estudio analiza el impacto de tres enraizadores diferentes en la producción de plántulas de dos variedades. Investigacion se realizó en distrito de Yanacancha Cerro de Pasco, el objetivo fueron determinar el efecto principal de tres hormonas enraizadoras, con dos variedades de espinaca: analizar la interacción AxB, la producción de raíces adventicias de plántulas de Espinaca (Spinacia oleracea), en condiciones almacigo tecnificado (cobertor) en condiciones de campo. Se investigaron dos variedades de espinaca: Imperial Green (a1) y Viroflay (a2), tres hormonas enraizadoras: Rizogen (b1), Roothort (b2) y Auxigen(b3), Se utilizó el diseño completamente al azar (DCA), se evaluaron las condiciones de almacigado: Variedad Imperial Green (a1) donde tuvo mayor longitud de raíz, diámetro de plántula, peso de plántula. La variedad Viroflay (a2), presento el mayor número de plántulas de descarte antes del transplante. En la variedad Imperial Green, y Viroflay. La hormona Auxigen (b3) dieron mayores resultados: longitud de raíz, diámetro, peso de plántula, otras hormonas presentaron menor porcentaje de plántulas de descarte. Resultados Las hormonas (Rizogen, Roothort y Auxigen) presentaron similar efecto en: masa radicular, masa foliar, porcentaje de prendimiento, altura de planta a la cosecha, rendimiento de hoja verde. Resultados obtenidos fueron con las hormonas en la masa foliar; Auxigen y Roothort, respecto a Rizogen no dieron efectos en: masa radicular, masa foliar, porcentaje de prendimiento, altura de planta, rendimiento de hoja verde. Conclusión el efecto de las hormonas enraizadoras fue más evidente en almacigo que en campo definitivo.
The study analyzes the impact of three different rooting agents on the production of seedlings of two varieties. Research was carried out in the Yanacancha Cerro de Pasco district, the objective was to determine the main effect of three rooting hormones, with two varieties of spinach: analyze the AxB interaction, the production of adventitious roots of Spinach (Spinacia oleracea) seedlings, under conditions technical storage (cover) in field conditions. Two varieties of spinach were investigated: Imperial Green (a1) and Viroflay (a2), three rooting hormones: Rizogen (b1), Roothort (b2) and Auxigen (b3), a completely randomized design (DCA) was used, evaluated seeding conditions: Imperial Green variety (a1) where it had greater root length, seedling diameter, seedling weight. The Viroflay variety (a2) presented the greatest number of discarded seedlings before transplanting. In the Imperial Green variety, and Viroflay. The hormone Auxigen (b3) gave greater results: root length, diameter, seedling weight, other hormones presented a lower percentage of discarded seedlings. Results The hormones (Rizogen, Roothort and Auxigen) had a similar effect on: root mass, leaf mass, yield percentage, plant height at harvest, green leaf yield. Results obtained were with the hormones in the leaf mass; Auxigen and Roothort, compared to Rizogen, gave no effects on: root mass, leaf mass, yield percentage, plant height, green leaf yield. Conclusion the effect of rooting hormones was more evident in the seedbed than in the final field.
