连续 8年调查了富士、金矮生、甜黄魁及国光无病毒树的树高、冠径、干径、每株树的新枝总数、新枝总长等生长指标和进入初结果期的结果株率 ,均表明明显高于同品种、同树龄有病毒对照树。无病毒金矮生、富士和甜黄魁品种每株树的累积结果量分别比有病毒对照树高 54 .7%、45 .0 %和 41 .6 %。无病毒富士、金矮生及国光果实硬度明显大于相应品种的对照果 ;维生素C、总糖、总酸及果皮中花青苷含量均高于相应品种的对照。
For eight consecutive years, the tree height, crown diameter, stem diameter, total number of new branches per tree, total length of new branches, and the results of entering the early fruiting stage of Fuji, Jinmusu, Tianhuangkui and Guoguang virus-free trees were investigated. , Both showed significantly higher than the same breed, with the same tree age virus control tree. The cumulative results per tree of virus-free gold dwarf, Fuji and sweet-kui tree varieties were 54.7%, 45.0% and 41.6% higher than that of the virus-control tree respectively. Virus-free Fuji, gold dwarf and Guoguang fruit firmness was significantly greater than the corresponding varieties of control fruit; vitamin C, total sugar, total acid and peel anthocyanin content were higher than the corresponding varieties of control.
