摘　　要：１９８５年用四环素、青霉素处理苎麻花叶病病株，症状并未减轻。用４％ＰＴＡ负染方法对病叶汁液进行电镜观察，在Ｃ２－１４、芦竹青、细叶绿品种中均见到线状病毒粒子．３次嫁接试验表明可使健康接穗产生相同症状，进一步证实此病由线状病毒引起．Mosaic diseased plants of Romie were treated with tetracycline and penicillin in1985 but no symptom changes were observed.The diseased leaves sap was negatively stainedwith 4%PTA and observed with electron microscope,and linear virus microsome have beenobserved in varieties of C2-14,Luzhuqing and Xiyielu. Three times of grafting causes thesame symptom in healthy plants,which proves that the disease is caused by linear virus mi- crosome.
