| 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1 g和2 g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,2 g叶片的抑菌率大于1 g叶片;8种植物2 g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. |

| Abstract: |
| 【Objective】 The comparison of the inhibition effect on the biogenic volatile organic compounds 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 hybridaVilm.,Celosia cristataⅠ,Celosia cristataⅡ,Tagetes erectaL.,Coleus blumei,Brassica oleracea var.acephala,Oxalis triangularis) to Escherichia coli,Staphylococcus aureus,Bacillus subtilis and Saccharomyces 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 antibacterial rates of 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 ofC.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.cristataⅡ didn’t have the ability to inhibit S.cerevisiae.【Conclusion】 C.blumei,B.acephala,P.hybrida Vilm. and S.splendens had stronger antibacterial activities,therefore,they could be viewed as ideal choice for ecological healthy virescence mode in cities. |
