Abstract:
Taking South Africa Wedelia as experimental object,the pink Impatiens as material,effective components of Impatiens leaves were extracted by water 95% ethanol and acetone impregnate and water balance，physiological changes and fresh liquid changes of Wedelia cut flowers in vase period were researched with three kinds of concentrations of three kinds of agent of 0.010,0.005,0.0025 g/mL respectively,which could provide reference for the function of Impatiens leaves as well as the preservation technology of fresh cut flowers.The results showed the three kinds extractions had strong preservation effect on fresh-keeping of Wedelia cut flower,the best was Acetone,95% ethyl alcohol better than water.The optimum concentration of extracts of three kinds of extraction methods on the preservation of Wedelia cut flowers was 0.005 g/mL.
