中文摘要 | 本研究乃探討柳杉種子苗林木及插條苗林木,其管胞壁孔形態、壁孔膜之構造及其大小數目在兩種林木內之差異情形及不同疏伐度對其所造成之影響。此外,並探討壁孔數在樹幹內徑向及樹高方向之變異情形及嘗試以一單對數數學模式TT(TR)=a+blog x;來表示管胞壁孔數在徑向分布之變化。及在成熟材與未成熟材境界時,壁孔數目之變異情形。TT(TR)為管胞壁壁孔數,x為距髓心年輪數。 |
英文摘要 | The objective of this study was to investigate systematically the differences in wood properties, in terms of the morphology of the pits of tracheid wall, the structure of pit membrane, as well as the numbers, the size, and the distribution of different types of pits, of Japanese ceder established either by seed or by vegetative cutting. Effects of various thinning intensities on all of these parameters were also studied. In addition, the variations of pit numbers along the radial and axial directions of the trunk as well as that along the demarcation between juvenile wood and mature wood were also illustrated using a semi-Iogrithmic model in the form of TT (TR) = a+ b logX, where TT (TR) is pit numbers and X is the number of annual ring from the pith. |
