摘要
对贵州省东北、东南、西南和西北４个地区悬钩子属（ＲｕｂｒｓＬ．）野生种类的分布、生长习性等进行了调查。共采集５５种７个变种，其中Ｒ．ｇｒａｙａｎｕｓ，Ｒ．ｍａｌｌｏｔｉｆｏｌｉｕｓ，Ｒ．ｔｓａｎｇｖｒｕｓ，Ｒ．ｆａｂｅｒｉ，Ｒ．ｈｅｎｒｙｉ为贵州省新记录种。Ｒ．ｓｅｔｃｈｕｅｎｅｎｓｉｓＲ．ｃｏｒｅａｎｕｓ，Ｒ．ｃｏｒｃｈｏｒｉｆｏｌｉｕｓ，Ｒ．ｌａｍｂｅｒｔｉａｎｕｓ，Ｒ．ｎｉｖｅｕｓ，Ｒ．ｍｕｌｌｉｂｒａｃｔｅａｔｕｓ，Ｒ．ｔｅｐｈｒｏｄｅｓ分布最广。除Ｒ．ｓｅｔｃｈｕｅｎｅｎｓｉｓ，Ｒ．ｔｅｐｈｒｏｄｅｓ外均有驯化利用价值。调查发现，具红、黄、黑三种不同果色的插田泡，秋季结果的小柱悬钩子、红泡刺藤和大乌泡。基本查清了贵州省悬钩子属植物的种类和分布，为进一步引种、保存和发掘利用提供科学依据。
Investigation of the distrib ution range and habitat,evaluation and collecting Of valuable species have been carried out by the Joint Sino-American Project in Guizhou. The field work was conducted in four areas:the northeastern part,including Jiangkou, Yingjiang,Songtao co unties around Fanjing Mt.Nature Preserve; southeastern part,mainly in Leishan,Rongjiang, Chongjiang,Liping counties around Leigong Mt. Nature Preserve;southwestern part,Xingyi,Anlong, ceheng,Wangmo, Luedian counties;and northwestern part Xishui,Bijie,Weining,Shuicheng,Nayong counties. Among 55species and 7 varieties collected,R. grayanus,R.mallotifolius,R.tsangorus,Rfaberi, R. henryi are new distribution reconis in the province,R.setchuenensis,R.coreanus,R.corchorifolius,R.parvifolius,R.lambertianus,R.multibracteatus and R.tephrodes are usually found as dominant species and those are thought worthy of utilization except R.setchuenensis and R.tephrodes.。 As a result of climatic and geographic in fluence etc.,variations happen ed within species distributed in different area,different types of R.coreanus with yellow fruits,red fruits,black fruits,and autumn fruiting R. multibracteatus,R.columellaris and R. niveus have been collected,Scien tific basis was provided by the. exploration for preservation and exploitation of Rubus germplasm resources in GuiZhou Province.
