Abstract: Taking Iris ensata cut flower whose single florescence was 2 d as the main test material, different CaCl2 was used to study the preservation effect and physiological response of Iris ensata cut flower. After pre-treatment at 4 ℃ for 24 h in 30 mg·L-1 sucrose+250 mg·L-1 8-HQ+1000 mg·L-1 CaCl2, the results showed that CaCl2 played a certain role in prolonging vase life of Iris ensata cut flowers. The vase life of the first flower was prolonged to 6.3 d, about 3.7 d longer than the control group. Two buds of I. ensata cut flower could bloom normally and the whole vase life could be 11 d. Meanwhile, it had a good effect on increasing the fresh weight of flower stem, reducing the degradation rate of soluble protein, enhancing the activities of SOD and inhibiting the increase of MDA in I. ensata cut flower.
