摘要
[目的]调查长白山区野生桔梗资源的现状。[方法]对长白山区24个点的野生桔梗的生境和生长情况进行调查,采集样本并种植保存。[结果]现存的野生桔梗大多数生长在生境较恶劣或偏远、人迹稀少的地方,因其生境比较恶劣,根小而没有利用价值或不易采挖而幸存。野生桔梗的性状表现明显劣于栽培桔梗。[结论]该研究为分析长白山区野生桔梗的遗传多样性和建立长白山区野生桔梗种质资源库奠定基础。
[ Objective] The aim was investigate the status of wild Playtcodon grandiflourus resources in Changbai Mountain Area. [ Methods ] The habitats and growth environment of the wild Playtcodon grandiflourus were investigated, and made a collection of the germplasm resources at 24 sites in Changbai Mountain Area. [ Result] Most of the existing wild Playtcodon grandiflourus, which survived because of its small roots that means no value and poor or remote conditions that leads to much difficult to dig. The character of wild Playtcodon grandiflourus was obvi- ously inferior to cultivated Playtcodon grandiflourus. [ Conclusion ] This study lays a foundation for the genetic diversity analysis and the establishment of germplasm resource pool of wild Playtcodon grandiflourus in Changbai Mountain Area.
