Hidrogeles derivados de acrilamida y ácido itacónico como soporte en medios de cultivo de plántulas de papa

Abstract

Hidrogeles de poliacrilamida (PAAm) y de poli(acrilamida-co-ácido itacónico) (P(AAm-co-AI)) sintetizados en agua y en una solución acuosa de buffer de fosfato al 0,2 M, fueron usados como soporte en los medios de cultivo de tejido vegetal sistema autotrófico hidropónico (SAH) y cultivo in-vitro con solución nutritiva Murashige-Skoog (MS) para la producción de plántulas de papa (Solanum Tuberosum, L). En los bioensayos realizados fue evaluado el comportamiento de los hidrogeles mediante el análisis de las características morfológicas de las plántulas: longitud de la parte aérea, longitud de la raíz, número de entrenudos y biomasa. Estos parámetros fueron analizados aplicando el análisis de varianza ANOVA de dos factores con múltiples muestras, en donde los factores evaluados fueron el tipo de hidrogel y el solvente usado para su síntesis. Los resultados obtenidos muestran que según el medio de cultivo estas variables se ven favorecidas por el uso de un determinado tipo de hidrogel, es decir, en el SAH los hidrogeles de PAAm son los que presentaron mejores resultados desde el punto de vista morfológico y estadístico. Para el cultivo in-vitro con solución nutritiva MS, las propiedades morfológicas de las plántulas, se vieron beneficiadas por el hidrogel de P(AAm-co-AI) sintetizado en la solución acuosa de buffer de fosfato. Palabras clave: Hidrogeles, medios de cultivo, Poliacrilamida, Poli (acrilamida-co-ácido itacónico). ABSTRACT Hydrogels from poly (acrylamide) (PAAm) and of poly (acrylamide-co-itaconic acid) (P (AAm-co-AI)) synthesized in water and in an aqueous solution of phosphate buffer 0.2 M, were used as a support in the vegetable tissue culture media hydroponic autotrophic system (HAS) and in-vitro culture with Murashige-Skoog (MS) nutrient solution for the production of potato seedlings (Solanum Tuberosum, L). In the bioassays carried out, the behavior of the hydrogels was evaluated by analyzing the morphological characteristics of the seedlings: length of the aerial part, length of the root, number of internodes and biomass. These parameters were analyzed by applying the ANOVA variance analysis of two factors with multiple samples, in which the factors evaluated were the type of hydrogel and the solvent used for its synthesis. The results obtained show that, according to the culture medium, these variables are favored by the use of a certain type of hydrogel, which, in the SAH the PAAm hydrogels are the ones that presented the best results from the morphological and statistical point of view. For the in-vitro culture with MS nutrient solution, the morphological properties of the seedlings were advantageous due to the P(AAm-co-AI) hydrogel synthesized in the aqueous solution of phosphate buffer.  Key words: Hydrogels, medium culture, Polyacrylamide, Poly(acrylamide-co-itaconic acid).
