| 摘 要： | 杜鹃花属(ＲｈｏｄｏｄｅｎｄｒｏｎＬ.)的系统学研究尚有许多值得探索的问题(余树勋,1986;闵天禄等,1990;Ｐｈｉｌｉｐｓｏｎｅｔａｌ.,1973)。近年来,本课题组陆续对浙江杜鹃花属植物开展了分类学和形态学的研究(丁炳扬等,1987;1989;1990;1995)。本文就浙江12种野生杜鹃花属植物的果实形态、种子数及其相关性进行研究,为该属的系统学研究及引种驯化提供理论依据。1 材料与方法11 常绿杜鹃亚属(ＳｕｂｇｅｎＨｙｍｅｎａｎｔｈｅｓ) 云锦杜鹃(Ｒ.ｆｏｒｔｕｎｅｉＬｉｎｄ1.)、猴头杜鹃(Ｒ.ｓｉｍｉａｒｕｍＨａｎｃｅ)、安徽杜鹃(Ｒ.… |

| Abstract: | In this paper, the variation in fruit shape, size and its seed number were studied, and the correlativity of length and diameter of fruit to seed number for 12 species of \%Rhododendron\% from Zhejiang Province were analyzed. Based on the fruit shape and the ratio of length to diameter, 12 species of \%Rhododendron\% L. Were divided into three types. The seed number varied in different species. \%Rhododendron ovatum\% had the highest seed setting efficiency, followed by the species of Subgen \%Tsutsusi\%. The variation of seed number among the individuals of the same species was more obvious than that of the fruit. There was a significant positive correlation between the seed number in fruits and the length, diameter of fruit in most species. The results showed that fruit morphology might be an important character in systematic studies of \%Rhododendron\% L. |
