8个柳树无性系冠形、主干分枝结构及生长比较研究

摘要

The clones of the willow are varied greatly and have diversified forms. Based on the different requirements of the willow woods such as timber-forest, shelter-forest and ornamental-forest, some fine species of the willow clones were analyzed such as: "Salix * jiangsuensis J172", "Salix * jiangsuensis J795", "Salix*aureo-pendula J1011" and some newly picked out species such as "Salix*jiangsuensis J549", "Salix*jiangsuensis J797", "Salix*jiangsuensis J335","Salix*jiangsuensisJ736","Salix*jiangsuensisJ1034",etc. The differences of their growth, crown -shapes and branching structures were especially introduced.%柳树无性系，变异大，形态多样，根据平原地区用材、防护、观赏的需要，对比分析柳树优良品种苏柳172、苏柳795、金丝垂柳1011和新选出的苏柳549、苏柳797、苏柳335、苏柳736、苏柳1034等新无性系的生长、冠形和枝干结构的差异。
