摘要
红豆杉属植物在全球有11种,均被所在国列为濒危树种保护名录。其主要分布于北半球,在北美洲和亚洲各有5种,欧洲有1种。其中欧洲红豆杉的栽培品种最多,有近100种。另外,杂种红豆杉的栽培品种也比较多,有50余种。剩余的9种红豆杉的栽培品种之和有50余种,很多红豆杉种没有选育出栽培品种。与世界各国相比我国红豆杉属植物的新品种选育进程缓慢,栽培品种很少。积极开展红豆杉属植物的种内、种间杂交研究,选育出具有园林观赏价值或其他经济价值的新品种是我国未来的育种目标之一。
There are eleven kinds of Taxus in the world, which are all classified as endangered species list by the host countries. They mainly distribute in the northern hemisphere with five species in America and Asia, respectively, along with one in Europe. Among these species, the cultivated varieties of Taxus baccata L. maintains the most in all kinds, approximately being one hundred. Additionally, the cultivated varieties of Taxus media Rehd. remains just less than Taxus baccata L. with about fifty or more. The total remainder of nine species in cultivated varieties accounts for about more than fifty. Therefore, lots of species of Taxus remains uncultivated. In comparison with the process for cultivated varieties in other countries, the process remains rather slower and the cultivated varieties were fewer. The active research on hybridization in and between Taxus family is necessary and selectively cultivating new varieties for ornamental value and other values are the main aim in the future.
