病毒病足番茄生长期的重要病害之一,主要症状类型有花叶、蕨叶、条斑、矮化及其复合症状。一般减产10~20%,严重的在50%以上。病果小而畸形,品质差,商品价值降低。引起番茄病毒病的毒原较复杂,常见的有烟草花叶病毒(TMV)、黄瓜花叶病毒(CMV)、马铃薯 x 病毒(PVX)、马铃薯 y 病毒(PVY)。防治时应据毒原种类和分布采取不同的措施。目前生产上采取的几种主要防治方法如下:1.采用抗病品种:番茄品种间存在着抗病性的差异,这些差异由抗性基因决定的。现代抗病育种就是根据各地病毒病的毒原种类和株系,利用具有
One of the most important diseases of tomato disease is tomato mosaic virus. The main symptoms are mosaic, fern leaf, streak, dwarf and their compound symptoms. The general cut 10 to 20%, serious in 50% or more. Sick small fruit and deformity, poor quality, lower commodity value. The toxins that cause tomato virus disease are more complicated. Common are TMV, CMV, PVX and PVY. Prevention should be based on the type and distribution of toxins to take different measures. The current production to take several main control methods are as follows: 1. Use of resistant varieties: There are differences between the resistance of tomato varieties, these differences are determined by resistance genes. Modern disease-resistant breeding is based on the types and strains of virulent virus around the use of
