Estabilidad de la membrana celular

A simple test for evaluating membrane stability is briefly described. In a comparison of 12 lines representing groups identified for cold, drought, or heat tolerance, cold tolerance was associated with greater membrane damage, and heat-tolerant materials showed the least damage. Drought-tolerant mat...

description A simple test for evaluating membrane stability is briefly described. In a comparison of 12 lines representing groups identified for cold, drought, or heat tolerance, cold tolerance was associated with greater membrane damage, and heat-tolerant materials showed the least damage. Drought-tolerant materials showed an intermediate level, which suggests that this group is not unusually heat tolerant, as some researchers had hypothesized. Preliminary data indicate that membrane stability or related techniques may provide a powerful tool for screening germplasm for temp. adaptation or drought tolerance. The technique is nondestructive, could easily be standardized, and appears to measure a basic characteristic of plant response to environment. (CIAT)

(CIAT) Se describe brevemente un ensayo simple para evaluar la estabilidad de la membrana. En una comparacion de 12 lineas representativas de grupos identificados por tolerancia al frio, sequia o calor, la tolerancia al frio se asocio con mayor dano de la membrana, mientras que los materiales tolerantes al calor mostraron el menor dano. Los materiales tolerantes a la sequia presentaron un nivel intermedio, lo que sugiere que este grupo no es extraordinariamente tolerante al calor, como algunos investigadores lo habian supuesto. Los datos preliminares indican que la estabilidad de la membrana o las tecnicas relacionadas pueden proporcionar una herramienta eficaz para la seleccion de germoplasma por adaptacion a la temp. o tolerancia a la sequia. La tecnica no es destructiva, se podria estandarizar facilmente y parece que mide una caracteristica basica de la respuesta de la planta al ambiente.
