Abstract

Rose is a principal cut flower in the world trade. Post-storage characteristic is one of the most crucial research problem of a cut rose flower, as they have a limited vase life due to xylem channel blockage and insufficient water absorption. Bacteria obstruct xylem vessels in the stem, which decreases the rate of water supply to flowers. The main aim of the study is to identify and standardize the hydration treatments to extend the vase life of shelf of cut roses. It was investigated whether nano-silver and nano-silicon particles could extend the vase life of cut rose flowers. Under carefully regulated circumstances, cut flowers were stored in vases holding various compositions of 5, 20, and 50 ppm of nano-silver, nano-silica, and dextrose solution treatments. Vase life, colour, form, texture, and appearance were all measured throughout this time. From the results it was found that nano silica reduced lipid peroxidation and stimulated antioxidant enzymes, while nano silver had antibacterial properties at low concentrations. In comparison to STS and silica, the results showed that modest concentrations of nano-silver and nano-silica treatments increased the lifetime of cut flowers. NHT9 gave good results compared to NHT14. The combination of dextrose, silica nano-particles, determined that nano silica particles stimulated the antioxidant enzymes and nano silver particles had a great capability for removing bacterial pollutants. These results implied that to enhance the overall quality and extend the vase life of cut roses, post harvest requires the application of solutions (NHT9- Nano Silver 5 ppm (10 ml) + Dextrose (2 gms) containing nano-silver and nano-silica (mostly nano silver) particles and dextrose.

Conclusion

The vase life of cut rose flowers was greatly increased by utilising nano hydration treatment with 5 ppm concentration of SNP and low concentration NSi, combined with the suppression of microbial development at stem ends. Silver ions move very slowly through the stems of rose blooms. Application of a nanoparticle with antibacterial properties can therefore increase the pace of that and lengthen the longevity of cut flowers. Although nano silica has an impact on vase life and sustaining floral quality along with SNP, its application must be applied quickly to extend the life of cut flowers. Therefore, using SNP (33 nm in diameter) instead of other silver compounds, along with 5% sucrose and 5 ppm of nano silica, is advised to prolong the vase life of cut roses.
