摘要: 西南地区丰富而独特的乡土杨树基因资源对杨树中长期遗传改良具有重要的意义。为有效保护和开发利用该区乡土杨树资源,对四川7个行政市(州)的共计31个县的乡土杨树种质资源进行了调查和收集,获得包括18个种及3个天然杂交种在内的乡土杨树单株材料1 560多份。根据该区乡土杨树多为异龄林的特点,在五株大树选优法基础上,制定了适用于异龄林的选优方法,获得乡土杨优树64株。结合林分优势木生长情况,制定了适合散生木选优的树高和胸径生长量标准。两种选优方法可供类似生态区的乡土杨树优树选择提供参考。

Abstract: The abundant poplar resources in southwest China have played an important role in the poplar genetic improvement.In order to protect and exploit the resources of the precious native poplars,germplasm resources collection and plus-trees selection were carried out in the regions of 7 municipalities and 31 counties in Sichuan,and 1 560 poplar samples belonging to 18 species and 3 natural hybrids were collected.Selection criterion of poplar plus-trees was established based on the comparison selection method,and 64 plus-trees were obtained.In terms of the growth characters of plus-tree in forest stand,the height and diameter criterions suited to the selection of plus-tree for scattered trees were established.Two methods will provide reference for selection of plus-trees in similar regions.

Key words: native poplar, germplasm resource, plus-tree, Sichuan
