摘要
对王林、乔纳金、长富２、秋富１、Ｍ７、Ｍ２６六个苹果品种及砧木的脱毒与未脱毒苗木进行测定，结果显示，脱毒后成叶中过氧化物酶活性显著降低。王林、长富２的脱毒苗成叶内硝酸还原酶活性比对照极显著增强。王林、乔纳金、长富２三品种脱毒苗成叶中蛋白质及氨基酸含量显著降低，幼叶及嫩梢皮层中蛋白质含量显著增高。脱毒后，三个品种成叶组织提取液褐变度明显降低。
In six apple strains or stocks, including Orin, Jonagold, Nagafu 2, Akifu 1, M7 and M26, the peroxidase activity in the mature leaves of the virus-free seedlings were obviously decreased, compared with oh (viruliferous ones). The nitrate reductase activity in the mature leaves of virus-free Orin, Jonagold and Nagafu 2 was also remarkably higher than their oh. The contents of protein and amino acid in the mature leaves of the three strains were much lower, but in the browses and the shoot cortex were higher, and nitrite concentration in them was decreased. After virus-free treatment the browning degree of the tissues extraction of the three strains was notably decreased.
