The Effect of Different Concentrations of Nano Silver Silicon and Calcium Compounds On Postharvest Life Of Rosa hybrida Dolce Vita Elham Ghanbari Ghanbari e91@yahoo com January 14 2013 Department of Horticultural Sciences Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language farsi Ali nikbakht anikbakht@cc iut ac ir Ali Akbar Ramin aa ramin@cc iut ac ir Abstract Rose Rosa hybrida from the Rosaceae family is the most important cut flower in the world Short vase life is one of the major problems of cut flowers Therefore applying methods which maintain flower quality and vase life are of importance The aim of this study was to investigate the effect of Silver nanoparticles Calcium nanoparticles and Silica nanoparticles and in comparison with their large particles Silver thiosulphate Calcium chloride and potassium silicates on the vase life of Rosa Dolce Vita This study was randomized complete block design with 5 separate experiments In esfahan university of technology s horticultural science lab were done during the years 2011 2012 Traits such as Vase life Relative fresh wight Solution uptake leaf relative chlorophyll content Chlorophyll fluorescence index Flower diameter pH maintenance solution and ion leakage measurements and were companded First and third experiment was factorial The second fourth and fifth experiment were conducted as split plot in time The third fourth and fifth experiment the pulsed for 12 hours were performed 4 replicates were used in all experiments First experiment with 4 treatments Concentrations 5 10 and 15 mg l each of nanomaterials with control continuously and second experiment with 4 treatments Concentration 15 mg l each of nanomaterials with control The pulse duration on 12 and 24 hours were performed The experimental results indicated a negative effect on all measured indices of nanomaterials The third experiment with 10 treatments Silver thiosulphate in three concentrations 0 5 1 and 2 mg L with control were performed and the results showed that high concentrations of potassium silicate 100 and 300 mg l had a positive effect on the measured parameters The fourth experiment with 7 treatments 10 mg l each of nanomaterials 1 mg l silver thiosulphate and 100 mg l of calcium chloride and potassium silicate with control was carried out The results showed that non nanomaterials treatments showed better effect on improving the physicochemical characteristics and vase life of cut rose flowers than nanomaterials In the fifth experiment 7 treatment including 10 mg l of each nanomaterials in preservative solution distilled water and 1sucrose distilled water as the control was carried out It was shown in this experiment that distilled water as the preservative solution was more effective than sucrose on the flower In general Particles in the bluk non nano than nano Scales preferred Potassium silicate as a new material for the improvement of the flowers is recommended Keywords Nanoparticles Toxicity of Nanoparticels Plant Toxicity Potassium silicate Vase Life Rose Dolce Vita PDF created with pdfFactory trial version www pdffactory com
