摘要
为了综合利用入侵植物，通过离体半叶枯斑法，对18种入侵植物提取物的抗烟草花叶病毒（TMV）活性进行了筛选，研究结果表明。垂序商陆、粉花月见草、三叶鬼针草、紫茎泽兰、飞机草、钻叶紫菀、苦苣菜、野茼蒿等9种入侵植物的提取物浓度为10mg／mL对TMV有不同程度的抑制活性，抑制率在59．15％～93．06％，这些具有抗病毒活性的入侵植物具有开发植物源农药的潜在价值。
In order to make use of invasive plants comprehensively, the anti-tobacco mosaic virus （TMV）activities of extracts from 18 invisave plants were screened by half-leaf method in vitro. At the concentration of 10 mg/mL extracts of Phytolacca Americana, Oenothera rosea, Oenothera stricta,Bidens pilosa L. ,Eupatorium adenophorum, Chromolaena odorata,A ster subulatus Michx. ,Sonchus oleraceus and Crassocephalum crepidioides showed moderate activity with the inhibition rate range of 59.15% to 93.06% ,and these invasive plants have the potential to be developed into plant pesticide.
