Abstract

The Tuberose cut flower is much less longevity in postharvest. The less vase life due to stress of deficit carbohydrate and quick respiration on inflorescence. In this study, effectiveness factors, sucrose, CaCl2, Al2So4 and re-cut the stems. In current research two separate experiments were arranged as a factorial based on compeletly randomized design. The first experiment were added to all experimental units have 100 ppm Al2So4 and investigation the effect of sucrose and CaCl2 factors. In the other experiment was added in all treatments of suitable sulation that obtain from first experiment (3.5 percent Sucrose and 200 ppm CaCl2) and investigation the effect of Al2So4 and re-cut stems factors. The vase life of cut flower, relative water content(RWC), a, b and total chlorophyll content were evaluated. The results of first experiment indicated the effect of reciprocal treatment with sucrose (3.5 %) and CaCl2 (200 ppm) increased significantly on the protection of a, b and total chlorophyll content and RWC, and increased the longevity at the time 16 days about 88 percent. The result of secondry experiment showed that the third important cause of reduced longevity of tuberose cut flower high susceptibility to blockage xylem, and treatment with protection sulation containing 3.5 % sucrose and 200 ppm Al2So4 and spray 200 ppm CaCl2 and Re-cut every 48 hourse were recommended for using to dissolve problems of post harvest the Tuberose cut flower.
