Abstract: Water metabolism and some physiological indexes of fresh cut Gladiolus flowers and cold-stored cut Gladiolus flowers in vase were investigated. The results showed that water uptake and water loss of cold-stored cut Gladiolus flowers were less than those of fresh ones at early stage. Compared with fresh cut Gladiolus flowers in the same phase in vase, soluble protein content of petals and bracts in different site of cold-stored cut Gladiolus flowers was lower, MDA content was higher, activities of CAT and POD were lower. Factors that caused the degradation of quality of cold-stored cut Gladiolus flowers were also discussed.

Key words: cut Gladiolus flowers, cold storage, water balance, quality, physiological change
