【摘要】 花生病毒病是目前严重影响河北省花生生产的主要常发性病害。在症状上主要有轻斑驳、黄花叶和普通花叶三种类型、系分别由花生轻斑驳病毒PMMV黄瓜花叶病毒CA株系CMV-CA和花生矮化病毒PSV侵染所致,PMMV还可分别与CMV-CA或PSV形成复合侵染。轻斑驳在全省各花生产区普遍发生,发病率高且年际间变化小,黄花叶和普通花叶仅在部分地区有发生,发病率在年际间变化比较大。黄花叶和普通花叶引起的产量损失在轻重两个发生年测定结果的平均值分别为38.1％和47.5％,轻斑驳症状表现较轻,对花生生育的影响较小,因此应将两种花叶病毒病作为综合防治的重点。更多还原

【Abstract】 Peanut’s Virosis is now a frequent disease that affects seriously peanut production in Hebei Province. It has three symptom types: mild-mottle, yellow-mosaic and common-mosaic, which result from PMMV, CMV-CA strain and PSV separately. PMMV can cause composed infection with CMV-CA or PSV. The mild-mottle occurred generally in all peanut areas in the province and the incidence is higher and changes a little between years. The yellow-mosaic and common-mosaic occurred in Part of the areas and there is a greater change for the incidence between years. The average estimated values of the yield loss caused by the yellow-mosaic and common-mosaic are 38.1％ and 47.5％ in lightly epidemic years and in seriously epidemic years respectively, but symptom of mildmottle is lighter and the average is smaller, So the yellowmosaic and the common-mosaic are treated as the focal points of comprehensive control.更多还原
