Abstract: The Phaeomeria magnifica was taken as the experiment material. The growth of flowering branches and ornamental characteristics were observed. The fresh-keeping treatments and moisture physiology were discussed. The results showed that the growth development of Phaeomeria magnifica flowers was 90d which could be compartmentalized four phase: flower-bud period, initiating bloom period, bloom period and wither period. The fading degree could be compartmentalized four grades. The best fresh-keeping effect was 2.0% sugar in four reagents. Fresh-keeping date was 11d with treatment C which containing higher concentration sugar and citric acid.
