摘　　要：　对"丝克高粱"外部形态和营养器官根、叶进行解剖研究及子实的颖片和叶表皮进行扫描电镜观察。结果表明:丝克高粱与"假高粱"营养器官的内部结构非常相似。在理论上丝克高粱有成为危险性有害生物的倾向。研究结果还进一步为正确鉴别假高粱和丝克高粱提供了重要依据。The micromorphological characteristics of 'Silk sorghum' ((Sorghum halepense × S.roxburghii)×S.arumdinaceum) had been observed,and its root,leaf and the glume had been anatomized with scanning electron and light microscope.The results showed that there were many same or similar characteristics between Silk sorghum and Johnson Grass(Sorghum halepense).There was a tendency in theory that Silk sorghum would be a dangerous and harmful organism.The research results offered an important basis on correct disinguishing between Silk sorghum and Sorghum halepense.
