本文介绍了白杨派无性系不同系号的纤维胞壁率,组织比量、纤维形态及变异性,对各单株的纤维胞壁率,组织比量,纤维长度,宽度及长宽比的平均值与对照的平均值进行了差异显著性检验。同时对胞壁率,组织比量,纤维长度、宽度及长宽比的水平变异进行了分析。纤维胞壁率为34.39—40.96%,纤维率为57.46—66.10%,导管率为25.93—32.78%,射线率为7.20—11.93%,纤维长度为0.889—1.186mm,宽度为0.0190—0.0235mm,长宽比为46.58—54.89。各项指标与年龄的关系为Y=a+bx c X~2;纤维宽度随长度的变化为抛物线关系。
In this paper, the cell wall rate, tissue proportion, fiber morphology and variability of different system numbers of Populus clones were introduced. The average cell wall ratio, tissue ratio, fiber length, width and aspect ratio Differences between the values and the control mean significant test. At the same time, the level variation of cell wall ratio, tissue ratio, fiber length, width and aspect ratio were analyzed. The cell wall rate was 34.39-40.96%, the fiber rate was 57.46-66.10%, the catheter rate was 25.93-32.78%, the radiation rate was 7.20-11.93%, the fiber length was 0.889-1.186mm, the width was 0.0190-0.0235mm, the length was The aspect ratio is 46.58-54.89. The relationship between each index and age is Y = a + bx c X ~ 2; the fiber width changes parabola with the length.
