摘  要:
1958年以来新疆哈密瓜由于花叶病毒的发生,使产量和含糖量严重降低。由病株分离出三种病毒,称谓哈密瓜病毒2、3和5。简称HMV2、HMV3和HMV5。HMV2:病毒颗粒为多面体,直径32毫微米,沉降系数(S_(20w))为90。寄主范围广,包括许多种植物,桃蚜(Myzus persicae)可以传病,与黄瓜花叶病毒抗血清有正反应,HMV2是黄瓜花叶病毒的一个株系。HMV3:病毒颗粒为多面体,直径28毫微米,超离心时沉降成三个成分,其沉降系数分别为51,85和104。寄主范围局限于葫芦科植物,蚜虫不传病。与南瓜花叶病毒抗血清有正反应,HMV3是南瓜花叶病毒的一个株系。HMV5:病毒颗粒为线状;大小为710×15毫微米,沉降系数为134,汁液和蚜虫传毒,除葫芦科植物外,还侵染苋色藜、豌豆和蚕豆。HMV5是西瓜花叶病毒的一个株系。

摘  要:
Since 1958,the mosaic virus diseases have caused a great reduction in yield and sugar content of Hami-melon(Cucumis melo var.Hami),a special local products in Xinjiang,China.Three viruses have beenisolated from the diseased melon,named Hami-melon mosaic virus 2,3,and 5,and designated as HMV-2,HMV-3 and HMV-5.HMV2:Virus particles are isometric,32nm in diameter,with a se-dimentation coefficient(S_(20)w) 90.Host range is wide,including manyfamilies.The virus is transmissible by Myzus persicae,and gave positivereaction with Cucumber mosaic virus antiserum.It was identified as astrain of Cucumber mosaic virus.HMV3:The virus sediments as three components,its sedimentationcoefficients(S_(20)w) are 51,85 and 104 respectively.Particles are isome-tric and appear about 28nm in diameter.Host range mostly limited tothe Cucurbitaceae with inoculation or sap.Not transmitted by aphids.It has been found it was positive to test the serological reactions ofHMV3 with Squash mosaic virus.It seems that HMV3 belongs to thSquash mosaic virus.HMV5:The virus with filamentous particles c.710×15 nm,sediment as a homogenous band with a sedimentation coefficient(S_(20)w)134.It is transmitted easily by mechanical inoculation and Myzus persicae.Beside Cucurbitaceae,it infects Chenopodium amaranticolor,Pisum sativumand Vicia faba.It is apparent that HMV5 is similar in such respects toWatermelon mosaic virus 2.
