摘要
历时4 a,调查了我国27个县(市)雷公藤属Tripterygium种质资源,建立种质资源收集库,定期观察雷公藤母本及无性系表型性状和生态适应性。结果表明,不同种质雷公藤的萌蘖性、生长势与造林成活率均存在差异,雷公藤T.wilfordii萌蘖性能明显优于昆明山海棠T.hypoglaucum,野生植株、种质资源收集库内母本及无性系后代均表现一致;在浙江丽水低海拔地区栽培,雷公藤造林成活率和幼林生长势也明显优于昆明山海棠。浙江类似地区雷公藤药材栽培应优先选用雷公藤,良种选育重点在雷公藤分布区内进行,既可提高良种选育效率,又可保证选育的良种适合丽水地区环境条件。
The objective is to provide bases for breeding Tripterygium cultivars with high quality and yield. By investigating resources in 27 counties of China, establishing genetic resource nursery, and observing and recording regularly the growth features of the maternal plants and their cline＇s offsprings, the ecological adaptability of Tripterygium plants were studied. The results show that there are differences of sprouting, growth potential and forestation＇s survival rates in different germplasms. T. wilfordii is better adapt to the environment of Lishui. than T. hypoglaucum and T. regelii. This species should be the first selection to culture for medicine in Lishui and other similar areas. The distribution areas of T. wifordii is the main region for highbred selection.
