一种可以使植物免疫真菌病害的新物质在苏联科学院生物化学研究所被研制成功。这种方法是根据使植物体内自身免疫物质活跃的原则,来免疫真菌病害的,而且,这种方法可以在马铃薯和甜菜上应用。它是用少剂量的新研制出的这种免疫物质处理马铃薯块茎的部分,在一至二天内,使马铃薯块茎表面组织的免疫力提高,一周后,整个马铃薯都具有免疫力,而且这种新获得免疫能力,可以由种薯传给新生成的块茎。在甜菜上的试验也已经证明,用 A new substance that can make plants immune to fungal diseases was successfully developed at the Institute of Biochemistry at the Soviet Academy of Sciences. This method is based on the principle of active substances in plants to immune fungal diseases, but also, this method can be applied to potatoes and sugar beet. It is the use of a small dose of newly developed immunological substance to treat part of the potato tuber that increases the immunity of potato tuber tissue within one to two days. After a week, the whole potato is immune, and the new gain Immune capacity, can be transferred from the seed tubers to the newly formed tubers. Experiments on beets have also been proven
