Abstract: The preservation effect and physiological biochemical changes during radish storage and the relationshipamong spongy degree. water content. respiratory strength and unit weight were studied.The conclusion showedthat rotted rate of radish applied with sodium alginate membrane is least rotted in natural normal atmospherictemperature during 3 monthes storage.The spongy degree had marked relation ship on water content,unit weight and respiratory strength of the radish.
