矮化病

She found the number of species is dwindling and some species are dwarfing due to selection pressure because only the smallest flowers remain unpicked.

她发现那些种类在缩小和矮化病其原因在选择的压力因为只有很小的花保留未摘。

By calculating the copy number of non-homologous template for QC-PCR detection of ratoon stunning disease, the standard RSD competition curve and linear regression equation were established.

通过计算非同源模板的拷贝数，进行竞争定量PCR检测宿根矮化病，建立宿根矮化病菌的标准竞争曲线和直线回归方程。

Since sugarcane ratoon stunting disease has caused a lot of serious damage in China, It is very necessary to study the control method of RSD.

甘蔗宿根矮化病(Ratoon Stunting Disease， RSD)在我国蔗区普遍发生，研究其防治方法十分必要。

Sugarcane mosic virus disease and sugarcane ratoon stuning disease harmful greatly on the yield and quality of sugarcane cultivation are widespread in the world.There is no any specific drug can control these diseases at present.Production and application of disease-free seed canes is an effective solution to control these diseases.

甘蔗花叶病(sugarcane mosic virus disease，SCMV)和宿根矮化病(ratoon stuning disease，RSD)是世界范围内广泛发生的两种病害，对甘蔗产量和品质造成重大影响，当前尚无特效药，生产上采用脱毒的健康种苗是控制这些病害的有效措施。

南瓜病毒病的典型症状为皱缩有疱斑、甚至扭曲，病叶畸形，植株矮化；花叶叶片上出现淡绿色和深绿色相间的斑驳，有的斑驳明显黄化；蕨叶丛枝型：病叶不但严重花叶、畸形，而且叶肉组织极度退化，纤细呈蕨叫叶状，病株黄绿色，节间明显缩短，整个植株严重矮化丛枝状。

The results showed that the virus-free plantlets were superior to the control in many characteristics such as germination,tiller,growth rate,plant height,diameter of cane,valuable stem and cane yield,and the cane yield increased by26.65%～69.39%.

在广西蔗区，花叶病、宿根矮化病已相当普遍，所有的栽培品种都受到不同程度的危害。这两种病已成为许多蔗区甘蔗单位面积产蔗量和产糖量提高的主要障碍因素。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
