Evaluación del crecimiento radial de Lactarius volemus en medio semisólido

Abstract

Resumen Objetivo. Evaluar el crecimiento radial de Lactarius volemus en cinco medios de cultivo semisólidos in vitro. Materiales y métodos. Cuerpos fructíferos de L. volemus provenientes de la Sierra Norte del estado de Oaxaca, México, se cultivaron en laboratorio en medios Agar Papa Dextrosa, Agar Czapek-Dox, Agar Extracto de Malta, Agar Papa Sacarosa y Agar Dextrosa Saboraud; mediante dos técnicas de sembrado. Se evaluaron las características morfológicas de colonias obtenidas de distintas muestras del cuerpo fructífero, así como el crecimiento radial de cada una. Resultados. El crecimiento colonial evaluado permitió seleccionar un medio que reúne las condiciones óptimas para el cultivo de Lactarius volemus in vitro. No todas las muestras utilizadas desarrollan un crecimiento abundante: la muestra proveniente del látex presenta un crecimiento escaso. Conclusiones. Con la evaluación del crecimiento radial de Lactarius volemus se obtiene una referencia directa del ciclo de crecimiento de esta especie; es posible identificar las fases exponencial y estacionaria pero las condiciones del medio no permiten evaluar la fase de muerte debido a la deshidratación y reducción del agar.

Abstract Objective. To evaluate the radial growth of Lactarius volemus in five semi-solid culture media in vitro. Materials and methods. Fruitful bodies of L. volemus from the Sierra Norte of the state of Oaxaca, Mexico, were cultured in the laboratory in Potato Dextrose Agar Papa, Czapek-Dox Agar, Malt Extract Agar, Potato Sucrose Agar and Dextrose Saboraud Agar; using two seeding techniques. The morphological characteristics of colonies obtained from different samples of the fruiting body were evaluated, as well as the radial growth of each one. Results. The evaluated colonial growth allowed to select a culture medium that meets the optimal conditions for the cultivation of Lactarius volemus in vitro. Not all samples used develop abundant growth: the sample from latex shows little growth. Conclusions. With the evaluation of the radial growth of Lactarius volemus a direct reference to the growth cycle of this species is obtained; it is possible to identify the exponential and stationary phases but the conditions of the medium do not allow evaluating the phase of death due to dehydration and reduction of the agar.
