大豆病毒病是大豆生产上的一个重要病害。近年,随着大豆蚜虫为害加剧以及新品种的选育和推广,使大豆花叶病有加重发生和为害的趋势。大豆花叶病毒侵染大豆植株后,常表现轻、重不同程度的花叶、叶脉坏死、叶片畸型、皱缩、黄斑、植株矮化、顶芽枯死及种皮斑驳等症状。品种间病害的发生程度存在差异。据国内报道,大豆花叶病的毒原种类很多,症状复杂。但对本病所造成的损失程度报道较少。为此,我们针对病害造成的产量损失;不同症状与毒原种类的关系及斑驳粒与病毒侵染的关系进行了以下研究工作。
Soybean virus disease is an important disease in soybean production. In recent years, with the aggravation of soybean aphid infestation and the breeding and popularization of new varieties, the soybean mosaic disease aggravates and harms the trend. Soybean mosaic virus infection of soybean plants often show light, heavy and varying degrees of mosaic, vein necrosis, leaf deformity, shrinkage, macula, plant dwarf, dead top buds and seed coat mottle and other symptoms. Differences in the occurrence of disease between varieties. According to domestic reports, many types of toxins of soybean mosaic disease, the symptoms are complicated. However, the extent of the loss caused by the disease reported less. To this end, we have carried out the following research work on the yield loss caused by disease, the relationship between different symptoms and poisonous species and the relationship between mottled grain and virus infection.
