9 Effect of Nano Silver and Silver Thiosulfate STS on Enhancing Vase Life of Cut Flower Alstroemeria Mehdi Makvandi Makvandi 2008 @yahoo com 5 July 2010 Department of Horticultural Sciences Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor A A Ramin aa ramin@cc iut ac ir Supervisor M Mobli Mobli @cc iut ac ir AbstractAlstroemeria is one of the most beautiful flowers and is considerd as one of the main tencut flowers throughout the world that allocate a high amount of cut flowers export to itself However little information is available on postharvest handling of this flower This factimplies more research for extending quality and is vase life The quality of cut Alstroemeriaflowers is often diminished by the petal shedding and premature yellowing of the foliage These two processes independent so that in some cultivars leaf yellowing occurred longbefore flower senescence and in others much later Thus the current research was carriedout in two independent investigates and five experiments to determine the effect ofdifferent chemical treatments on increasing primary florets longevity and inhibited foliaryellowing Alstroemeria cut flower cultivar Fortaleza At all experiments after treatments cut flowers were placed in preservative solution containing sucrose 1 During eachexperiment flowers were held at 20 2 0C 50 5 relative humidity and 12 h photoperiodunder cool white fluorescent light of about 800 lux These experiments were carried out onsplit plot in time in a completely randomize design CRD with three replications and eightplants per replication The effect of the treatments was evaluated by recording vase life days to periante abscise diameter area and color of primary florets chlorophyll content chlorophyll fluorescence yield Fv Fm water potential and longevity days to 50 yellowing of leaf and water potential of stem solution absorption relative fresh weightand percentage water of inflorescence Also at the beginning and end of each experiment pH of preservative solution was measured and compared The first investigation had a threeexperiments In the first and second experiment cut Alstroemeria stems were treated withdifferent concentrations including 0 1 2 and 3 mM of Silver thiosulfate STS and 0 5 10and 15 ppm of nanosilver respectively In the third experiment the best concentrations ofthese two substances was compared with control The experimental solutions were appliedas 24 h pulse treatment The results of the first experiment indicated that all thiosulfate STS treatments markedly extended vase life of primary florets chlorophyll chlorophyllfluorescence yield Fv Fm water potential of leaf and solution absorption relative freshweight and percentage water of inflorescence while it had negatively influenced on theopening rate of primary florets in comparison to the control Application of concentrationgreater than 2 mM Silver thiosulfate not only caused discoloration of the petals but alsoblackening of the bracts and was thus toxic The results of the second experiment showedthat various treatments of nanosilver did not have significant effect on the chlorophyll chlorophyll fluorescence yield Fv Fm of leaf compared to the control but had significantincreasing effect on vase life and diameter of primary florets water potential of leaf andstem solution absorption relative fresh weight and percentage water of inflorescence
