摘要
核桃科树种在全球分布甚广,但有关起源问题却存在争议,至今未有一致看法,成为长期悬而未决的问题。对此,许多学者做了大量的考证和研究,在他们工作的基础上对核桃科植物的起源和散布途径进行了初步探讨认为:核桃科树种是包括中国在内的多地起源;分布中心是中国东部到南部山地,随后扩展到欧亚大陆。
Tree species of Juglandaceae were distributed all over the world, but there are many different views about the origin of tree species of Juglandaceae so far. Based on the progress of present investigation and research, origin and distribution of tree species of Juglandaceae was researched. The results showed that tree species of Juglandaceae originated from several areas including China, and the center of distribution was from Eastern China to mountains of Southern China, and then they were introduced into Eurasia.
