苹果品种幼苗叶片接种褐斑病菌后,钙含量的变化是苹果—褐斑病菌相互作用的结果。苹果不同品种叶片感染病原菌后,钙含量普遍增加,表现为被动的病理生理变化,品种感病程度愈高,增加量愈大。进一步提出了钙在苹果品种对褐斑病的抗病性中可能的作用。 After inoculation of Corynebacterium pathogen in apple seedling leaves, the change of calcium content is the result of the interaction between apple and brown spot pathogen. Different varieties of apple infected with pathogens, the calcium content generally increased, showing a passive pathophysiological changes, the higher the degree of susceptible varieties, the greater the increase. Further proposed the possible role of calcium in the resistance of apple cultivars to brown leaf disease.
