美国ARS(农业研究服务社)以及密西 西比—牛津大学的学者共同发现,青苔中 的一种天然化合物可作为天然除草剂的来 源。 青苔是真菌与海藻共生的混合物,在 已知的2万多种类型中,只有极少数的几 种含有生物活性,这些化合物基本上苔鲜 细菌的代谢产物,并且大多有自己的独特 性,少部分——大约600种化合物中的 60种在其它细菌或更高级的植物中存 在。 US ARS (Agricultural Research Service) and scholars at the University of Mississippi - Oxford jointly found that a natural compound in moss can be used as a source of natural herbicides. Moss is a symbiotic mixture of fungi and seaweeds. Of the more than 20,000 known types, only a very small number of them contain bioactivities. These compounds are essentially metabolites of mossy bacteria and mostly have their own uniqueness and little Part - about 60 of about 600 compounds are present in other bacteria or higher plants.
