摘要
用半叶枯斑法,在心叶烟上测试了33种植物乙醇提取物水溶液对烟草花叶病毒(Tobacco mosaicvirus,TMV)侵染的抑制效果。结果表明,雪松、桉树提取物能较好地抑制病毒(TMV)侵染,抑制率达到89.7%,78.3%;此外,菟丝子、红花蔷薇、桑、红千层、杜鹃、桂花、香石竹、滇厚朴、荠菜、芦荟等植物提取物也具有抑制烟草花叶病毒(TMV)侵染的效果,抑制率均在50%以上。
Ethanol extracts from thirty-three kinds of plant were tested for inhibiting Tobacco mosaic virus（TMV） infection by using half leaf technique on Nicotiana glutinosa.The results showed that the extracts of Cedrus deodara（Roxb.） G.Don and Eucalyptus maideni F.V.Muell performed better inhibitory activities to TMV infection comparing other plant species.The inhibition percentage were 89.7%and 78.3%,respectively.The extracts of Cuscuta chinensis Lam.,Rosa moyesii Hemsl.et wils,Morus alba L.,Callistemon rigidus R.Br,R.simsii planch,Osmanthus fragrans（Thunb）Lour,Dianthus chinensis L.,Ehretia coryltfolia C.H.Wight,Brassica juncea（L.） Czern.et coss,Aloe vera（L.） Burm.f.showed inhibitory effect as well.The inhibition percentage all of them were over 50%.
