ABSTRACT In the autumn of 2010, in a replanted orchard in the research garden of the University of Natural Resources and Life Sciences in Vienna, the apple cultivar ‘Topaz’ was planted on the rootstocks M.9 (clone T337) with inter-stem ‘Summerred’, G.11, CG.13, G.16, G.41, G.202, M.7 and MM.111. The trees have been growing according to organic production standards, and were observed for nine years. G.11 and G.41 showed good results, even if tree losses due to crown rot (Phytphthora cactorum) in combination with the highly susceptible cv. Topaz were high, compared to the standard M.9 with inter-stem. G.11 was similar to M.9 in growth but had higher fruit yield. G.41 grows 10% more vigorously with good yield results, and is therefore ideal for replanting orchards. The other tested rootstocks from Geneva did not prove to be suitable.

日内瓦砧木对有机管理再植果园中苹果栽培品种“黄玉”营养和繁殖特性的影响

摘要 2010 年秋季，在维也纳自然资源与生命科学大学研究园的一个改种果园中，在砧木 M.9（克隆 T337）上种植了苹果品种‘Topaz’，茎间有‘ Summerred'、G.11、CG.13、G.16、G.41、G.202、M.7 和 MM.111。这些树木一直按照有机生产标准生长，并被观察了九年。G.11 和 G.41 显示出良好的结果，即使由于冠腐病（Phytphthora cactorum）与高度易感的 cv. 组合导致树木损失。与标准 M.9 相比，托帕石的含量很高。G.11 在生长方面与 M.9 相似，但果实产量更高。G.41 生长旺盛 10%，产量高，因此是果园补种的理想选择。来自日内瓦的其他经过测试的砧木被证明不适合。
