摘　　要：研究了纳米银和1-MCP处理对月季切花‘卡罗拉’瓶插寿命和花径、相对鲜重(RFW)和瓶插液吸收(VSU)、相对叶绿素含量和丙二醛(MDA)含量、相对电导率以及抗氧化能力的调节作用。结果表明:与对照相比,纳米银和1-MCP单独处理与组合处理均能显著提高花瓣还原力,提升抗坏血酸过氧化物酶(APX)、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性,降低花瓣中丙二醛(MDA)含量和叶片中相对电导率,并抑制叶绿素含量的下降。与纳米银和1-MCP单独处理相比,纳米银和1-MCP组合处理对延长月季切花瓶插寿命、增大切花花径、促进切花吸水、维持切花的质膜稳定性和提升切花的抗氧化能力更为有效。总之,纳米银和1-MCP组合处理可通过维持切花的水分平衡和质膜稳定性、提高切花的抗氧化能力、降低切花的膜脂质过氧化水平来延长月季切花的瓶插寿命。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.
