Abstract

Abstract: In order to accelerate development of storage and transportation technique of Taraxacum mongolicum,the effects of storage temperature on its postharvest physiology and quality were studied and the optimal storage temperature was explored.The changes of external appearance,nutritional ingredient contents,and postharvest physiology were investigated at 25℃,10℃,2℃,-18℃ storage temperature.The results indicated that with the increasing of storage time,the leaves etiolated,contents of crude-fiber increased,while vitamin C,chlorogenic acid decreased,nitrate contents up to the maximum at the 3th day after storage,then decreased gradually.Stored at 2℃,the contents of chlorophyll,vitamin C,chlorogenic acid were higher,nitrate and crude-fiber contents were lower.The lower of membrane permeability and MDA content,the higher activity of SOD significantly delayed senescence process and prolonged storage life of Taraxacum mongolicum.
