improvement vase life of chrysanthemum (dendranthema grandiflorum l.) cut flowers using essential oils of geranium, eucalyptus and myrtus

this study carried out based on a randomized completely design with 10 treatments geranium, eucalyptus and myrtus extraction, in 3 levels (2, 6 and 10 ml in 600 ml of distilled water) and control (distilled water) with 3 replications in 30 plots and each plot with 4 cut flowers. in this experiment traits such as vase life, water absorbtion, fresh weight, dry matter percent, petal protein content, petal carotenoids, leaf chlorophyll content, lipid peroxidation (mda), sod and pod enzymes activity and bacterial population were measured. the results showed that 2 ml myrtus the per 600 ml was the longest vase life compared to control (9.74 days) increased the vase life of 5.99 days. the highest bacterial population was observed in control plants. also, the lowest mda was found in 2 ml myrtus oil.
