已有的少数报道表明,荞麦真菌和病毒病传播很广,危害很大。根据我们用荞麦育种材料(用杂交方法,试验诱变处理等获得的)、品种、野生近缘植物进行病理学鉴定的资料,最危险的是灰腐病、霜霉病和病毒灼伤病等病害。根据植物免疫在许多方面决定于组织、器官构造的解剖学形态学特点、细胞汁化学成分、专化性物质(如具杀菌剂性能物质)存在的概念,本文试图探明制约荞麦真菌和病毒病

A few reports have already shown that buckwheat fungi and viruses spread widely and are very harmful. According to our pathological identification data using buckwheat breeding materials (obtained by hybridization, experimental mutagenesis, etc.), varieties, and wild relatives, the most dangerous are ash, downy mildew and virus burns . In many respects, plant immunity is determined by the anatomical features of the tissue and organ architecture, the chemical composition of the cell juice, and the concept of the presence of specialized substances (such as fungicides). This article attempts to elucidate the mechanisms that control buckwheat fungal and viral diseases
