摘要
1967 年,来自 15 到 25 个产地的黑胡桃 (Juglans nigra L.) 树苗被种植在美国中西部的八个地方。1973 年,在俄勒冈州扬卡拉附近建立了一个类似的种植园。结果表明,在该树种的自然分布范围内,可以向北移动 200 英里而不会受到寒害。一般来说,来自南方的树木生长速度超过来自北方的树木。
Growth Gains from Moving Black Walnut Provenances Northward
In 1967, black walnut (Juglans nigra L.) seedlings from 15 to 25 provenances were planted at eight locations in the Midwest. In 1973, a similar plantation was established near Yoncalla, Oregon. Results show that, within the species' natural range, provenances can be moved as much as 200 miles northward without the likelihood of cold damage. In general, growth of trees from southern sources exceeds that of trees from northern sources.
