云南古桂的资源现状及保护利用

对分布于云南不同地理区域的21株树龄在百年以上古桂的现状、生长环境、当地政府或群众对古桂的保护意识及保护状况等进行了调查。结果表明,21株古桂均为栽培起源。其中11株分布于古寺庙庭院,其他则在村舍及学校栽培。目前4株古桂已经自然死亡或被毁,1株的主干已被砍去。在分析云南古桂的保护现状和生长状况的基础上,就如何开展云南古桂花种质资源研究、保护和合理利用提出了具体建议。

Status of Ancient Sweet Osmanthus in Yunnan and the Considerations of Their Feasible Protection and Utilization

Some 21 individuals of sweet osmanthus aged more than 100 years was recorded in Yunnan of south-west China. Current investigations revealed that all the plants belong to the cultivation origin, and about half of them are in the Chinese Religion-temple yards and others are growing in the villages. Four of the 21 individuals died naturally, and 1 of them has been seriously damaged. Based on the analysis and discussion of growth and protection of the ancient sweet osmanthus in Yunnan, some urgent research works on cultivar ranks and genetic base, and feasible approaches on protection and resources utilization have also been proposed in the paper.
