摘要
【目的】比较我国北方地区常见的8种园林绿化草本花卉植物叶片挥发性物质的抑菌效果，为园林绿化中植物的合理配置提供依据。【方法】采用皿内试验，测定8种供试植物（一串红、矮牵牛、鸡冠花I、鸡冠花Ⅱ、万寿菊、彩叶草、羽衣甘蓝、紫叶酢浆草）的1g和2g整叶、碎叶，对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌及酵母菌的抑菌率，比较其抑菌效果的差异。【结果】所有供试植物叶片的挥发性物质均具有一定的抑菌活性，一般碎叶的抑菌率大于相同质量的整叶，2g叶片的抑菌率大于1g叶片；8种植物2g碎叶对大肠杆菌的抑菌率为14．84％～66．41％，其中彩叶草、羽衣甘蓝和矮牵牛的抑菌率超过50％；对金黄色葡萄球菌的抑菌率为23．93％～54．70％，其中仅彩叶草的抑菌率超过了50％；对枯草芽孢杆菌的抑菌率为11．82％～65．59％，其中彩叶草、一串红和万寿菊的抑菌率超过了50％；对酵母菌的抑菌率为34．91％～74．52％，其中一串红、矮牵牛、羽衣甘蓝和彩叶草的抑菌率超过了50％，而鸡冠花Ⅱ的挥发性物质对酵母菌无抑制作用。【结论】彩叶草、羽衣甘蓝、矮牵牛、一串红具有较强的抗菌活性，是较为理想的城市生态保健型绿化模式栽培植物。
[Objective] The comparison of the inhibition effect on the biogenic volatile organic corn pounds of 8 kinds of common landscape herbaceous plants in north of China could provide a basis for the rational distribution of plants in landscape. [Method] The antibacterial rate of 1 g and 2 g whole leaves and broken leaves of 8 kinds of tested plants （Salvia splendens Ker-Gawl, Petunia hybrida Vilm. , Celosia cris tata I , Celosia cristata Ⅱ , Tagetes erecta L. , Coleus blumei , Brassica oleracea var. acephala, Oxalis trian- gularis ） to Escherichia coli , Staphylococcus aureus , Bacillus subtilis and Saccharom yces cerevisiae were determined with the method of testing in dish, and then the difference of their antibacterial activity was compared. [Result] All of the bacteriostasis from the tested plants had antibacterial activities to a certain extent. Regularly,the antibacterial rate of broken leaves was greater than that of whole leaves of the same quality,and the antibacterial rate of 2 g leaves was greater than that of 1 g leaves. The antibacterial rate of 2 g broken leaves of the 8 kinds of plants against E. coli was 14.84%--66.41% ,among which the antibac- terial rates of C. blumei,B, acephala,P, hybrida Vilm. were more than 50%. The antibacterial rate against S. aureus was 23.93%--54.70% ,among which the antibacterial rate of C. blumei was more than 50% only. The antibacterial rate against B. subtilis was 11.82%--65.59% ,among which the antibacterial rates of C. blumei,S, splendens, T. erecta L were more than 50%. The antibacterial rate against S. cerevisiae was 34.91% -- 74.52%, among which the antibacterial rates of S. splendens, P. hybrida Vilm. , B. acephala, C. blumei were more than 50% ,but C. cristata Ⅱ didn＇t have the ability to inhibit S. cerevisiae. [Conclusion] C. blumei , B. ace phala , P. h ybrida Vilm. and S. s plendens had stronger antibacterial activities, therefore, they could be viewed as ideal choice for ecological healthy virescence mode in cities.
