Abstract :
This research is to investigate the effect of different plant essential oils on some quantitative, qualitative characteristics and vase life of Alstroemeria spp. flowers, in the form of a factorial experiment based on a completely randomized statistical design with 11 treatments, 3 replications and each replication containing 5 The flower branch was executed. After harvesting, alstroemeria flowers were placed in preservative solutions containing thymol, cineole and menthol at levels of 25, 50 and 75 mg/l along with 3% sucrose. Distilled water and 3% sucrose were also used as controls. The results showed that cineole 75 mg/liter treatment had the greatest effect on improving cell membrane stability index, solution absorption, polyphenol oxidase enzyme activity and vase of alstroemeria cut flowers. The highest relative fresh weight, amount of soluble solids of the stem and petal anthocyanin on menthol 75 mg/liter treatment were obtained. The thymol 75 mg/liter treatment had the greatest effect in increasing the total leaf chlorophyll content and peroxidase enzyme activity compared to the control treatment. Also, the longest vase life of alstroemeria cut flowers was 16.3 days in cineol 75 mg/l treatment and the lowest was 9.7 days in the control treatment. Therefore, according to the results of the research, it is possible to recommend the use of plant essential oils to improve vase life of alstroemeria cut flowers.
