石河子地区菠菜病毒发生十分严重,其病状以皱缩,花叶、畸形、矮化为主。1986年我们从本院菠菜上表现皱缩花叶、畸形和矮化的典型病株上得到一个病毒分离物:SP—1,经寄主范围测定,它可以浸染豆科、茄科、藜科和番杏科的各种植物,并可以通过汁液摩擦和桃蚜传毒。光学显微镜下捡查。病毒细胞内有不定形内含体。病毒的致死温度为57℃～59℃,稀释限点为10_-~3～10_-~4,体外存活期9天以上。电镜观察病毒粒体为球形,大小25毫微米左右。据上述特性和有关资料分析,鉴定为蚕豆萎焉病毒。近年来,石河子地区菠菜病毒病的发生愈来愈重。据调查不少地方发病率达80％以上。重病田越冬前即可造成大量死苗。越冬后有时死苗率也达50％以上。对菠菜产量影响很大。田间症状主要表现为花叶、皱缩,还有疱斑和黄化等类型。大部分情况下这些症状混合发生,病株均严重矮化。现就皱缩花叶型病林上的分离物的鉴定简介如下。
Shihezi spinach virus is very serious, its symptoms to shrinkage, mosaic, deformity, dwarfism. In 1986, we obtained a virus isolate from the typical diseased plants of the court with spinach, deformities and dwarfs: SP-1, which can be soaked in Legume, Solanaceae, Chenopodiaceae Aliciaceae various plants, and can be juice poison and peach aphid poisoning. Pick up the light microscope. The virus cells have indefinite inclusions. The lethal temperature of the virus is 57 ℃ ~ 59 ℃, the dilution limit is 10_ ~ ~ 3 ~ 10_ ~ ~ 4, and the in vitro survival time is more than 9 days. Microscopic examination of electron microscopy spherical, about 25 nanometers in size. According to the above characteristics and analysis of relevant information, identified as Fusarium Wane virus. In recent years, Shihezi spinach virus disease is more and more serious. According to the survey in many places the incidence of more than 80%. Severe disease before winter can cause a lot of dead seedlings. Winter moth sometimes over 50% after winter. Great impact on spinach production. Field symptoms mainly for the mosaic, shrinkage, as well as blister and yellow types. In most cases, these symptoms occur mixed, severe dwarf disease. Now on the crimple mosaic disease isolates identified as follows.
