【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,各品种无病毒树分别比对照高出6.4%～16.0%,冠径大9.8%～15.9%,干径多8.9%～17.4%;每树的新枝数多12.7%～24.4%,新技总长多23.1%～40.6.2年生无病毒金矮生的结果株率达60.0%,有病毒对照树为16.7%.3年生无病毒富士结果株率为48.0%,对照为16.0%.无病毒国光3年生结果株率达62.5%,4年生为97.5%;有病毒树3年生结果株率为0%,4年生为12.5%.无病毒甜黄魁每株累积结果量比有病毒树多41.6%,金矮生多54.7%,富士多45.0%.无病毒 富士、金矮生及国光果实硬度分别比有病毒果大8.8%～22.3%;抗坏血酸含量多11.1～30.8%;总糖含量高0.74%～0.95%;总酸含量高0.04～0.08%.更多还原

【Abstract】 the virus - free trees of Fuji, Gold Spur, Tianhuangkui and Ralls have been investigatedfor 8 years. Compared with the control trees, the henght of virus - free trees increased 6.4% ~ 16.0%, the crown diameter increased 9.8% ~ 24.4% , the trunk diameter increased 8.9% ~ 17.4% ,The new branches of per tree increased 12.7% ~ 24.4% ,the total new branch length increased 23.1% ~ 40.6% . The bear-ing tree percentage of biennial virus - free Cold Spur reaches 60.0% , but the virus control tree reaches 16.7% , the bearing tree percentage of triennial virus - free Fuji reaches 48.0%, but the control tree reaches 16.0% , that of triennial virus- free Ralls is 62.5% , that of four year old Ralls is 97.5% ,but that of triennial virus Rails is zero, that of four year old Ralls is 12.5%. The bearing fruit of virus - free Tian-huangkui is 41.6% more than that of virus control tree. Cold Spur is 54.7% . Fuji is 45. 0% . the fruit hardness of virus - free Fuji, Cold Spur and Ralls is 8.8% ~ 22.3% harder than that of the virus control trees. The ascordic acid content is 11.1% ~ 30.8%, the total sugar content is 0.74% ~ 0.95% , the total aeid content is 0.04% - 0.08% .更多还原
