Graphene oxide(GO) has excellent properties due to its basal carbon plane and oxygen-containingfunctional groups. In the present work, the antimicrobial activity of GO wasexploited to extend the vase life and improve the quality of cut roses (cv. Carola).The results revealed that the cut roses cultivated in low doses of GO (0.1 mg/L)had longer vase life, larger diameter, and better water relations. Microbialcontaminations at the basal stem end is the most common reason for stemblockage that causes water stress and early wilting of cut flowers. GO wasfound to act as a germicide, effectively inhibiting the microbial growth atthe cut stem end and improving water uptake and water balance of cut roses.Therefore, GO can serve as a promising preservative to increase the ornamentalvalue of cut flowers. 关键词：graphene OXIDE CUT FLOWER ANTIMICROBIAL water transport VASE life
