study on interaction effects of mechanical and geranium essential oil treatments on vase life of cut chrysanthemum (dendranthema grandiflorum l.)

The aim of this study is investigation on effect of stem end splittingand geranium essential oil on vase life on quality of cut chrysanthemum(dendranthema grandiflorum l.). this experiment arranged as factorial basedon rcd with 2 factors of stem end splitting at 2 levels (with splitting andwithout splitting) and geranium essential oil at 6 levels (0, 1, 2, 4, 8 and 10%), with 12 treatments, 3 replications, 36 plots and 144 cut flowers. in this experimenttraits such as vase life, water absorption, fresh weight, dry matterpercent and °brix were measured. anova showed that different amongtreatments was significant for vase life, °brix and fresh weight in 1% probabilityand for dry matter percent and water absorption in 5% probability. resultsshowed that different treatments improved vase life compared to control andmaximum vase life was achieved in 5 cm splitting + 10% geranium essentialoil with 18.41 days compared to control (7.05 days).
