Effects of Plant Density and Harvest Time and Preservative Solutions on the Vase Life of Gladiolus (Gladiolus grandiflorus cv. Chloe)

solutions on the vase lite of gladiolus, a research was conducted on the cut flower of gladiolus c.v. Chloe. This experiment was done based on the complete randomized block design as factorial with 3 plant density (gO, 100, 120 plarus/rn) and two different times (morning and allernoon). determine the best preservative solutions, flower pots in S,-~ 8-lIydroxyquinolin (300 ppm) + sucrose (4%) + Acid citric (1000 ppm) , S, ~ silver nitrate (300 ppm) + sucrose (4%) + Acid citrict 100 ppm). Were Considered Some of qualitative characteristics (flower stem diameter, spike length, floret diameter, number otopcn iloretsts, number of wilted florets and vase life of cut flowers) were studied. Results indicated that with reduction of plant density (80 plants-nr) floret diameter, spike length and number of open florctsts increased and number ofwilted florets reduced ( P ~ 1%). Also, the results indicated that there was a significant difference between two harvest times, morning and allernoon (P = 1%). In morning harvest floret diameter, number of open florets and vase life 0 f cut flowers increased and The number of wilted florets decreased. Also, the vase life of gladiolus increased in R- Hydroxyquiuolin (300 ppm j: sucrose (4%) + Acid citric (1000 ppm) treatment
