Efecto del pH y el peso inicial de implante sembrado en la multiplicación callogénica de canavalia ensiformis

Este trabajo evalúa el efecto del pH del medio de cultivo en la multiplicación callogénica de Canavalia ensiformis. Con el fin de obtener datos para un crecimiento óptimo de la biomasa callogénica, se determinaron dos rangos de trabajo, el primero comprendido entre 4.5 y 5.5 y el segundo entre 5.5 y...

description Este trabajo evalúa el efecto del pH del medio de cultivo en la multiplicación callogénica de Canavalia ensiformis. Con el fin de obtener datos para un crecimiento óptimo de la biomasa callogénica, se determinaron dos rangos de trabajo, el primero comprendido entre 4.5 y 5.5 y el segundo entre 5.5 y 6.0, determinando el efecto que este producía en la multiplicación callogénica. Así mismo, se observó que la cantidad de callo sembrado inicialmente influye en el aumento de la biomasa. Luego de realizar un análisis de varianza a los datos de siembra obtenidos, se encontró que el mejor pH para el medio de cultivo es de 5.5, mientras que el peso del callo a ser sembrado debe ser mayor de 0.2500 gramos, con el fin de realizar una propagación adecuada de C. ensiformispara la obtención de metabolitos de interés comercial.

In order to obtain data for optimal growth of biomass callogenic, two work ranges were determined, the first between 4.5 and 5.5 and second between 5.5 and 6.0, determining the effect it produced on callogenic multiplication. Also, it was observed that the amount of seed callus affects the increase of biomass. Then an analysis of variance to planting obtained data , it was found that the best pH for the culture medium is 5.5, whereas the weight of the callus to be sown should be greater than 0.2500 grams, in order to realize was made C. ensiformis propagation adequate for commercial production of metabolites of interest.spaExecutive Business School ChileIngeniería AmbientalFacultad de Ingenieríashttp://www.redalyc.org/html/3236/323631115006/Avances en Ciencias e Ingeniería, vol. 5, núm. 2, abril-junio, 2014, pp. 73-83Barjafidalgo, C., Guimaraes, J.A. & Carlini, C.R.
