摘要
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。
The virus-free trees growth and fruit production of‘Fuji’,‘Gold Spur’,‘Tian Huangkui’and‘Ralls’have been investigated for 8 years,as compared with the control trees,the height,crown and truck diameter of virus-free trees increased 6.4%-16.0%,9.8%-15.9%,and 8.9%-17.4% respectively.The new branches and total new branch length per tree increased 12.7%- 24.4% and 23.1%-40.6% respectively.The bearing tree percentage of biennial virus-free Gold Spur, triennial virus-free Fuji,triennial and 4-year-old virus-free Ralls reached 60.0%,48.0%, 62.5% and 97.5% respectively,but the virus tree reached 16.7%,16.0%,0 and 12.5% respectively.The number of bearing fruit in virus-free Tian Huangkui,Gold Spur and Fuji were 41.6%, 54.7% and 45.0% respectively higher than that of virus control tree.The fruit hardness of virus-free Fuji,Gold Spur and Ralls is 8.8%-22.3% harder than that of the virus control fruit.The contents of ascordic acid,total sugar,total acid and anthocyanin in fruits of virus-free trees were all higher than those of control trees.
