【摘要】 本文对6个柳树无性系(349柳、106柳、208柳、180柳、111柳5个无性系及对照109柳)在木材密度、气干干缩率、木纤维形态及综纤维素含量等方面进行了比较研究。结果表明：在木材密度方面，349柳、106柳、180柳显著高于对照；在气干干缩率方面，349柳、106柳显著低于对照；在木纤维形态方面，349柳、106柳、208柳木纤维长度显著高于对照，5个无性系木纤维宽度显著高于对照；在综纤维素含量方面，106柳、349柳、208柳、180柳显著高于对照。基于以上研究结果，筛选出349柳、106柳、180柳为优良无性系。更多还原

【Abstract】 In this paper, the wood density, air-dry shrinkage rate, wood fiber morphology, and holocellulose content of six willow clones(349, 106, 208, 180, 111 and 109) were compared. The wood densities of clone 349, clone 106, and clone 180 were significantly higher than that of clone 109. The air-dry shrinkage rates of clone 349 and clone 106 were significantly lower than that of clone 109. The fiber lengths of clone 349, clone 106, and clone 208 were significantly higher than that of clone 109. The fiber widths of five clones were significantly higher than that of clone 109. The holocellulose contents of clone 106, clone 349, clone 208, and clone 180 were significantly higher than that of clone 109. Based on the above results, clone 349, clone 106 and clone 180 were selected as excellent clones.更多还原
