Gerbera flower nowadays because of it’s diverse colour high economic importance in the floriculture industry. The aim of this study Effect of different plant essence containing Thymus vulgaris, Cuminum cyminum, Eucalyptus Rosemarinus officinalis (50, 75 and 200 mg/L) with sucrose 3% as continuous treatment and distillate water as a control on Gerbera cut flower were studied. Vases containing cut flowers kept in room with environment condition include: average temperature 24◦ C , relative humidity 70% and photoperiod 14 hr light supplemented with light intensity about 15 to 20 μmol/m2/sec with fluorescent lamps. Treats such as longevity, solution uptake, stem bending, membrane stability index, anthocyanin content of petals and activity of superoxide dismutase enzymes in petal at certain days were evaluated and statistically analyzed. Results revealed that pulse treatment of Thymus vulgaris at 50 mg/l ,and cuminum cyminum 100 mg/l concentration along with sucrose 3% significantly increases solution uptake and quality of cut flowers. Also this treatment increases anthocyanin content of petals, membrane stability index and total soluble solid of stem flower. The rate activity of catalase and super oxide dismutase enzymes in all treatment contrast with control showed decrease at lower rate. Vase life of Gerbera cut flowers in all treatments regard to control significantly increases.
