One of the most popular cut flowers in the world is the rose. An obstacle is that cut roses have a naturally short vase life. One of the main causes of shortened vase life is microbial contamination. This study assessed the effects of nanoparticle vase holding solutions on Taj Mahal rose variety water relations and microbial load. The Postharvest Technology Laboratory, College of Horticulture, Bengaluru, is where the current study was conducted. Water absorption, transpiration loss, water balance, and microbiological load were all measured during the vase time. The greatest options for preserving water relationships and preventing bacterial growth were nanosilver treatments. The best benefits were seen in flowers that were kept in 50 ppm nanosilver. This study reveals the fact that, in the present context, silver nanoparticles are one of the best available technologies in delaying the postharvest associated degradation in rose cut flowers.
