摘　　要：对6个种源28个家系粗皮桉木材纤维长度、宽度、长宽比等纤维形态特征进行了分析,探讨其制浆造纸适应性,为制浆造纸原料的定向培育和合理利用提供一定的理论依据。研究结果表明,不同种家系的粗皮桉的纤维长度、宽度、长宽比的差别范围较大。其中纤维长度分布在0.7728-0.9766mm之间;纤维宽度分布在21.22-27.92μm之间;长宽比分布在31.02-45.97之间。大部分家系粗皮桉的纤维形态特征比较符合制浆造纸原料的要求。其中,6个种源中家系30、130、5、205、233、270和161的制浆造纸适应性较好。This passage analyses the fiber morphology of 28 families Eucalyptus pellita of different seedlots. Through testing the fiber length, width and length-width ratio, it can provide some theoretical basis on the rational use and cultivation of raw material . The results show that the range of the fiber length is from 0.7728 mm to 0. 9766 mm; the range of the fiber width is from 21. 22μm to 27.92μm;the range of the length-width ratio is from 31.02 to 45. 97. Fiber morphology of most Eucalyptus pellita families conforms to the requirements of raw material used in pul- ping and papermaking. Families 30,130, 5,205,233,270 and 161from different seedlots are more suitable for pulping and papermaking.
