摘要:: 选择普通丝棉木实生苗中观赏效果最好的1株作为母株，将其枝条通过高接换头，嫁接在普通丝棉木上，繁育大叶丝棉遗传性状丝棉木，将其命名为“花之都”长椭圆叶丝棉木。与普通丝棉木相比，其典型特征为枝条直立，硬度较大，分枝角度小，树冠紧凑；叶型呈椭圆形，叶片超大，花量较少，结籽能力差，对尺蠖有较强抗性，生物学性状稳定，未发现变异或返祖现象，具有很好的应用和推广前景。

Abstract:: The best ornamental seedlings of common silk-cottonwood were selected as the mother plant,then grafted the branches to other common silk-cottonwood by high grafting and transposed to bred genetic traits of large-leaf silk-cottonwood,which was named as ‘Huazhidu’ long-oval leaf silk-cottonwood.Compared with common silk-cottonwood,‘Huazhidu’ long-oval leaf silk-cottonwood exhibited more upright branches,greater hardness,smaller branch angle,compacter crown,bigger leaves,fewer flowers and seeds,stronger resistance to geometer,as well as stable biological properties.Thus,‘Huazhidu’ long-oval leaf silk-cottonwood would have a good prospect of application and promotion.
