摘要
研究水淹程度对枫杨木射线的影响 ,结果表明 ,两组间木射线宽度和高度在径向上的变化基本一致 ,而在轴向上变化却不同。在 0 .0 5水平上 ,经 T -检验两组间的木射线宽度、高度、形状因子。
The experimental results showed that the width of ray(RW) and height of ray(RH) of the two groups varied similarly in radial while differently in axial.The differences of the RW, RH, form factor, average border area of cell per volume and average area of cell between the two groups were not significant at 0 05 level.
