摘要:对来自浙江省临海市黑杨派南方型17 个新无性系和3 个对照无性系的木材性状的系统研究表明:20 个无性系树干纤维长度为0.966 0 ～ 1.143 0 mm, 均达到国际木材学会规定的中级纤维标准, 基本体积质量为0.318 8 ～ 0.368 2 gcm-3 ;树枝条的纤维长度为0.630 0 ～0.780 0 mm , 基本体积质量有0.344 2 ～ 0.400 8 gcm-3 ;各材性状在无性系间均具有显著或极显著的差异, 且纤维长度和木材基本体积质量均具有较高的遗传重复力(0.473 7 ～ 0.833 3), 胸径与树干基本体积质量呈中等程度的遗传负相关。木材性状间均具有较高的遗传正相关。所测定的17 个新无性系中, 367 , 366 , 370 和351 等4 个无性系在生长和材性上尤其突出, 其生长量和材性均优于目前制浆性能较佳的69 杨, 是营建培育纸浆材和纤维材为目标的短伐期林的首选无性系。表4 参10

Abstract:A systematic study made in Linhai on wood properties of paper pulpwood of 17 new clones and other 3 clones as a control shows that the fiber length in the trunk of these 20 clones ranges between 0.966 0 and 1.143 0 mm , which has met the standard laid down by the International Timber Society for the fiber of middle rank and the specific gravity of the trunk is from 0.318 8 to 0.368 2 gcm-3 ;that the fiber length of branches ranges from 0.63 to 0.78mm and their specific gravity is from 0.344 2 to 0.400 8 gcm-3 ;that each clone differs from the other in timber properties either significantly or most significantly ;and that both fiber length and specific gravity have a relatively high genetic repetition (0.473 7 ～ 0.833 3).Genetically speaking , DBH is moderately in negative correlation between timber properties .Such 4 clones among 17 new clones as 367 , 366 , 370 and 351 are very prominent in growth and wood properties , their growth and wood properties being superior to those of Populus deltoides cv . 'Lux' that is best in pulping at present .Therefore , these four clones are a top choice for establishing a short-rotation forest armed at producing paper pulpwood and fiber wood .
