Preservation effect of nano silver and 1-MCP treatment on cut rose
The effects of nano-silver and 1-MCP treatment on vase life and flower diameter,relative fresh weight(RFW)and vase solution uptake(VSU),relative chlorophyll content and malondialdehyde(MDA)content,relative conductivity and antioxidant capacity of cut rose'Carola'were studied.The results showed that compared with the control,the single and combined treatment of nano-silver and 1-MCP could significantly improve the reducing power,increase the activities of ascorbate peroxidase(APX),superoxide dismutase(SOD)and catalase(CAT),decrease the content of malondialdehyde(MDA)in petals and the relative conductivity in leaves,and inhibit the decrease of chlorophyll content.Compared with nano-silver and 1-MCP alone,the combined treatment of nano-silver and 1-MCP was more effective in prolonging the vase life,increasing the diameter of cut flowers,promoting the water absorption of cut flowers,maintaining the plasma membrane stability of cut flowers and improving the antioxidant capacity of cut flowers.In conclusion,the combination of nano-silver and 1-MCP can prolong the vase life of cut rose by maintaining the water balance and plasma membrane stability,improving the antioxidant capacity and reducing the membrane lipid peroxidation level of cut flowers.
