COMPARISON EFFECTS OF SILVER NANOPARTICLES, GLYCEROL AND ALUMINIUM SULPHATE AS VASE HOLDING SOLUTIONS ON VASE LIFE ATTRIBUTES OF CUT ROSE (ROSA XHYBRIDA) VAR. TAJ MAHAL
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
Rose is one of the most sought after cut flowers globally. The naturally short vase life of cut roses is an impediment. Concerted efforts have always been taken up to tackle this issue. In this study, effects of vase holding solutions on water relations of rose var. Taj Mahal were evaluated. The present study was carried out at the Postharvest Technology Laboratory, College of Horticulture, Bengaluru. Flowers were held in five preservative solutions containing sucrose + citric acid and also in combination with 50 and 20 ppm nanosilver, glycerol (6%) and aluminium sulphate (300 ppm). During vase period, water uptake, relative fresh weight, transpiration loss and water balance were measured. Both the nano silver treatments extended the vase life compared to the other treatments. Among these treatments, the concentration of 20 ppm SNP in combination with sucrose 1.5% + citric acid 300 ppm showed the highest water uptake and highest relative fresh weight (%) till the final day of study. This study emphasizes the fact that, in the present context, silver nanoparticles are one of the best available technologies in delaying the postharvest degradation in rose cut flowers.
