- 摘要:
- 以四川省螺髻山杜鹃属(Rhododendron L.)植物为试材,采用实地调查的方法,研究了野生杜鹃属植物的种质资源种类及分布情况,以期为更好的保护和开发利用野生杜鹃属植物资源提供参考依据。结果表明:1)螺髻山杜鹃属植物资源丰富。共有45个种,属于常绿杜鹃亚属、杜鹃亚属、糙叶杜鹃亚属和映山红亚属4亚属,以常绿杜鹃亚属和杜鹃亚属为主,其中丹巴杜鹃等11个种在该区域未曾报道。2)采集杜鹃属植物标本变异较大。螺髻山所采集杜鹃属植物标本有33种在质量性状和/或数量性状与模式标本存在差异,并对39个杜鹃属种进行形态特征补充。3)在螺髻山区域内杜鹃属植物于海拔1 600~3 980 m呈垂直和块状分布。螺髻山是野生杜鹃属植物资源保护及开发利用的宝库。
- Abstract:
- The wild Rhododendron (Ericaceae) resource were used as the test materials on Mount Luoji in Sichuan Province,China.In order to better protect and utilize the wild Rhododendron resources,the species and distribution of the wild Rhododendron resource were studied based on the field survey.The results showed that,1) Rich species of resources.45 species of wild Rhododendron were identified in the Mount Luoji area,which were classified into four subgenera (Hymenanthes,Rhododendron,Pseudorhodorastrum,and Tsutsusi),with species in the subgenera Hymenanthes and Rhododendron being the predominant taxa.Moreover,11 species of Rhododendron were collected which previously had not been reported.2) Species which were collected with morphologies differing from those of the type specimens.We identified 33 species for which the specimens differed from the type specimens in terms of qualitative and/or quantitative characters,and supplement morphology characters of 39 species Rhododendron which incompletely characters of type specimens.3) The Rhododendron showed clear patterns of vertical and block distribution between elevations of 1 600 m and 3 980 m on Mount Luoji.Therefore,the suggestion about enhancing the wild Rhododendron plant resource protection and develop,on Mount Luoji.
