摘要

日本核桃(Juglans ailantifolia carriires)被认为是库页岛非常罕见的本土树种。在岛上的天然阔叶混交林中，没有关于黄叶松的记录。乌格列戈尔斯克行政区的乌格列戈尔卡河和纳德姆河流域被认为是叶黄的主要栖息地。我们发现来自这些地点的所有核桃树都属于年龄超过95岁的人工林。结果表明，叶黄是20世纪初从日本引进的库页岛现代植物群的外来种。

Is the Japanese walnut (Juglans ailantifolia, Juglandaceae) native to Sakhalin Island?

The Japanese walnut (Juglans ailantifolia Carrière) is considered a very rare native tree species to Sakhalin Island. There is no information about J. ailantifolia records in the natural broad-leaved mixed forests of the island. The valleys of the Uglegorka and the Nadym Rivers in the Uglegorsk administrative district were noted as the main habitats areas of J. ailantifolia in several sources. We found that all walnut trees from these locations belong to artificial forest stands over 95 years old. We conclude that J. ailantifolia is a non-native species to the modern flora of Sakhalin and was introduced from Japan at the beginning of the XX century.

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
