70年代以来,山东沿海地区曾严重发生小麦花叶病毒病。病叶最初呈线条状褪绿,严重时整株叶片变黄,矮化以至枯死。土传小麦花叶病毒(Soil-borne Wheat Mosaic Virus)国外已报道较多,国内蔡文启等人于1983年对山东崂山地区土传小麦花叶病毒进行了生物学、理化性质、分子杂交、病毒形态以及血清学(琼脂免疫双扩散)等方面的鉴定。 但由于琼脂免疫双扩散法看不到病毒形态,而电镜观察虽可见其形态,却又无专化性。为此,我们对山东沿海地
Since the 1970s, wheat mosaic virus disease has been severely affected in Shandong coastal areas. The diseased leaves were initially chlorotic green, severe yellow leaves when the entire plant, dwarf and even dead. Soil-borne wheat mosaic virus (Soil-borne Wheat Mosaic Virus) has been reported abroad, the domestic Cai Wenqi et al in 1983 Laoshan region soil-borne wheat mosaic virus in biology, physical and chemical properties, molecular hybridization, virus morphology And serological (agar immune double diffusion) and other aspects of the identification. However, due to agar immune double diffusion method can not see the virus morphology, while electron microscopy can see the morphology, but no specialization. To this end, we are on the coast of Shandong
