Abstract :
This study was conducted to evaluate the effect of preservative
solutions on vase life, number of bacteria in the end of stem and in vase
solution of cut gerbera ʹDouble Dutchʹ and ʹRed Explotionʹ. Cut flowers
were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg L-1) and thymol
(12.5, 25, 50, 75 or 100 mg L-1) + 5 % sucrose. Experiment was conducted
in completely randomized design with 5 replications and 1 flower in each
experimental unit. Flower were harvested from a commercial greenhouse
and transported to laboratory with 22±1?C temperature and 60±5% relative
humidity. According to the results, these materials had positive effects on
vase life of flowers. 6 mg L-1 nano-silver treatments in ‘Red Explotion’
cultivar had highest longevity (14 days). All treatments were effective on
decreasing of bacteria in stem end and solution. In 4 and 6 mg L-1 SNP
treatments was not any bacteria in vase solutions of ‘Red Explotion’ cultivar.
Resulty showed that nano-silver can be use for increasing the vase life of
cut gerbera ‘Double Dutch’ and ‘Red Explotion’.
