Abstract :
Effect of Benzyladenine(50, 100 and 150 mg/L-1) with sucrose at 8% concentration as pulse treatment(48 hr) andnano silver particle 5 ppm and distilled water as continuous treatment( preservative solution) on Gerbera cutflower were studied. Vases containing cut flowers kept in room with environment condition include, averagetemperature 20◦C , relative humidity 70% and photoperiod 14 hr light supplemented with light intensity about 15μmol/m2/sec with fluorescent lamps. Treats such as vase life, relative fresh weight, of membrane stability index,anthocyanine content of petals and activity of catalase and superoxide dismutase enzymes in petal in certain dayswere evaluated and via statistically analyzed. Results show that pulse treatment of benzyladenine with 150 mg/L-1 concentration with sucrose 8% and preservative solution with nano silver particle 5 ppm significantly increasesrelative fresh weight and quality of cut flowers. Also this treatment increases anthocyanine content of petals andmembrane stability index. Activity of catalase and super oxide dismutase enzymes in all treatment contrast withcontrol showed decrease activity with lower rate. Vase life of Gerbera cut flowers in all treatments regard tocontrol significantly increases
