| 摘 要： | 对鸡毛松（Ｐｏｄｏｃａｒｐｕｓｉｍｂｒｉｃａｔｕｓ）、竹柏（Ｐｏｄｏｃａｒｐｕｓｎａｇｉ）、长叶竹柏（Ｐｏｄｏｃａｒｐｕｓｆｌｅｕｒｙｉ）、百日青（Ｐｏｄｏｃａｒｐｕｓｎｅｒｉｆｏｌｉｕｓ）和罗汉松（Ｐｏｄｏｃａｒｐｕｓｍａｃｒｏｐｈｙｌｕｓ）进行了ＲＡＰＤ分析。经筛选４组８０个引物，发现９个引物的带型清晰并呈多态性。采用ＵＰＧＭＡ法对求出的遗传距离进行聚类分析，得到的结果显示：本研究中的植物明显地分为３个亚类群，支持在罗汉松属内建立竹柏组的处理方式，不同意把竹柏类从罗汉松属中分离出去成立新科的观点

| Abstract: | Choosing Podocarpus imbricatus, Podocarpus nagi, Podocarpus fleuryi, Podocarpus neriifolius and Podocarpus macrophyllus are analysed through the RAPD techniques. Eighty primers from 4 operon kits were screened and 9 of them were able to produce clear polymorphic patterns. The results generated by using UPGMA algorithm to cluster genetic distances calculated from RAPD data imply: 1)the studied species are apparently clustered into three subgroups, which supports the treatment of constructing corresponding sections, Sect. Dacrycarpus, Sect. Nageia and Sect. Podocarpus in the genus Podocarpus , 2)it is unreasonable to separate nageiaoids from Podocarpus and to establish a new family named Nageiaceae. |
