胡杨锈病(Melanpsora pruinosae Tranz)是一种毁灭性的病害。这种病害发生频繁,蔓延迅速,对胡杨苗木危害极大。长期以来,经自然选择和遗传变异,胡杨已分化出多种类型,它们中有的类型对胡杨锈病表现出一定的抗性和免疫能力。本试验正是通过大面积的调查和接种试验,筛选和鉴定抗病型胡杨的形态特征,以及过氧化物酶同工酶与抗病的关系,从而为生产实践提出了防治胡杨锈病的生物学措施和选育抗病类型的理论依据。
Poplar rust (Melanpsora pruinosae Tranz) is a devastating disease. This disease occurs frequently, spread rapidly, great harm to poplar seedlings. For a long time, Populus euphratica has been divided into many types by natural selection and genetic variation. Some of them showed some resistance and immunity to Populus euphratica. This experiment is through a large area of investigation and vaccination test, screening and identification of morphological characteristics of resistant Populus euphratica, and peroxidase isozymes and disease resistance, thus put forward for the production of biological control of poplar rust The theoretical basis of measures and breeding types of disease resistance.
