An experiment was carried out to investigation on effect of different concentrations of Artemisia oil on vase life and other postharvest characteristics of cut chrysanthemum cv. White flowers. The experiment carried out based on randomized completely design with four levels of Artemisia oil (0, 10, 30,50%) at 3 replications. Results showed that maximum vase life, dry weight and fresh weight was achieved in 30% Artemisia oil with 10 days, 8.96g and 44.50g respectively
Chrysanthemum, Artemisia oil, Vase life, Fresh weight, Dry weight
Chrysanthemum (Dendranthema grandiflorum L. ) belong to family Asteraceae family is one of the popularand commerical cut flowers that grown on longer scale in the world [3, 11]. Senescence of cut flowers is induced by water stress, carbohydrate decline, bacterial contamination and etc [6, 17]. Use of preservative and antimicrobial compounds in vase solution such as humic acid [15], silver nano particles [12], 8-hydroxy quinoline sulphate [2] and etc improved vase life of cut flowers. Essential oil as novel natural compound and secondary metabolite that improves vase life of cut flowers [4, 5, 14, 18]. Solgi et al. [14] showed that essential oils and silver nanoparticles improved vase life and postharvest quality of cut gerbera cv. Dune flowers. Mousavi Bazaz and Tehranifar [5] reavaled that 50 and 100 mg l-1 essential oils improved weight yield, vase life and water relation in cut Alstromeria flowers. The aim of this study is investigation on effect of natural preservative compounds on vase life, fresh weight and dry weight of cut chrysanthemum cv. White.
Fully opened cut chrysanthemum cv. White flowers were purchased from Mahallat and then transported to postharvest laboratory of Department of Horticulture, Islamic Azad University, Rasht (Iran) with 20±2 °C 60- 70% relative humidity, 12 μmol s-1m-2 light intensity and 12 h photoperiod from florescent lamps. Experiment carried out based on randomized completely design with Artemisia oil at 4 levels of (0, 10, 30 and 50%) and 3 replications and 12 plots in each plot was 5 cut flowers. In this study, vase life, dry weight and fresh weight were measured. Vase life index was evaluated by wilting and yellowing of leaf and petal [13]. For determination of fresh weight, all flowers of each plot was weighted by Hashemabadi et al [8] method. Dry weight was calculated 24 h after fresh weight evaluation, flower were held in oven dry in 70° C and then weighted. Analysis of variance was done with SPSS and SAS softwares and mean comparison were established by LSD test.
Analysis of variance showed that effect of Artemisia oil on vase life, dry weight and fresh weight was significant (p≤0.05). Results showed that highest vase life, dry weight and fresh weight were achieved in 30% Artemisia oil with 10 days, 8.96 g and 44.50 g respectively (Table 1) (Figure 1).
Positive effect of Artemisia oil on these traits due to inhibiting suberin formation, improvement water relations, hydraulic conductance, antirespiratory properties, Maintaining carbohydrates and antimicrobial effect that finally prevent vascular blockage and increased fresh and dry mass and vase life of cut chrysanthemum cv. White [6, 8-10, 16, 19]. Mousavi Bazaz & Tehranifar [5] found that Mentha and Thymus oil maintained fresh weight and improved vase life of cut Alstroemeria flowers. Anju et al. [7] reported that antimicrobial compounds improved vase life and fresh weight of cut chrysanthemum flowers. Hashemabadi et al. [8] demonstrated that antimicrobial compounds increased dry matter in cut carnation cv. Tempo flowers. Our results also about positive effect of antimicrobial compound on vase life and postharvest quality agreement by Abdul Wasea [1], Mohammadi Ostad Kalayeh et al. [20] and Damunpola and Joyce [10].
In conclusion, Artemisia oil at 30% level improved vase life and increased postharvest index of cut chrysanthemum cv. White flowers.
