摘要
通过对乔纳金等３个苹果品种的１～３年生潜带褪绿叶斑病毒的树体与同品种无毒对照树的对比观测表明：苹果褪绿叶斑病毒对苹果树生长、开花结果及果实性状等，均有一定程度的危害。其中前者的干周、株高、枝类比、成花数量、产量和果实单果重等指标比后者的均低，其差异显著；
The CLSV seedlings of Jonagoldact 3 cultivars of apple were transplanted in the fields for 4 years in order to appraise their response of adaptability and growth and fruiting. Through 4 years detection, those CLSV trees tended to have a less girth and height and scaffold limb and flowering rate and yield and average weight of fruit than virus free trees of the same cultivars. The initial flower tree age of CLSV trees were one year late than that of virus free trees.
