摘要
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。
Post-infectional changes of content in apple leaves were due to the apple-pathogen interactions, Ca content in infected leaves of three varieties increased generally. It appeared to be a passive physiopathology change, there would be higher increase with more susceptible variety. It was further raised the possible role of calcium in resistance of apple varieties to the apple blotch.
