我们发现象牙海岸的四棱豆(Psophocarpus tetragonolobus)有三种病害.其中两种已经证实是病毒,即由丝状病毒引起的坏死花叶病和由园形病毒引起的环点花叶病.第三种病害可能也是病毒.但迄今为止的研究还不能确定.本文介绍了这三种病害的症状及其对四棱豆发育的影响,还有这些病原的传播和业已鉴定过的病毒的性质等等初步研究成果.1976年“雀巢基金会”从加纳和新几内亚把四棱豆引进象牙海岸,旨在研究儿童吃了四棱豆之后对发育有何影响.四棱豆的蛋白质含量很丰富,种子含30%,种荚含6—15%,块茎含12%.象牙海岸目前只在两种类型区栽培四棱豆,一是低地,年雨量2300毫米,另一是森林与热带稀树干草原的边界,年雨量1500毫米.第一次栽培就发生病虫害,其中病毒病尤为重要.
We found three diseases of Psophocarpus tetragonolobus in the Ivory Coast, two of which have been confirmed to be viruses, the necrotrophic mosaic virus caused by the filamentous virus and the circular mosaic virus caused by the circular virus. The disease may also be a virus, but so far the study is uncertain. This article describes the symptoms of these three diseases and their effects on the development of the beans, the spread of these pathogens and the nature of the viruses identified Preliminary Findings 1976 Nestle Foundation introduced Gypsophila from Ghana and New Guinea to Ivory Coast in 1976 to study the effect children have on development after eating Pyrifolia.White beans are rich in protein and seeds 30%, seed pods 6-15%, tubers 12%. Ivory Coast is currently only cultivated in two types of field beans, one lowland, annual rainfall 2300 mm, the other is the forest and tropical savannah steppe Boundary, the annual rainfall of 1500 mm. The first cultivation occurred pests and diseases, of which the virus disease is particularly important.
