<正>研究了间歇性淹水对池杉木材管胞形态、纤丝角的影响。结果表明，间歇性淹水使池杉木材管胞长度、管胞直径、管胞壁厚下降；对纤丝角影响不明显。经Ｔ检验，其差异在０．０５水平下，除管胞弦向直径、纤丝角外皆显著。

The paper investigated the effect of intermittent flood upon the tracheid formation, microfibrilar angles of Taxodium ascendens. The results are as follows: longer tracheid lengths, larger tracheid diameters, thicker tracheid walls, larger microfibrilar angles of wood without intermittent flood are characteristics of wood. The Ttest values indicated that the tracheid width in tangential direction and microfibrilar angle are of no significant differences between wood with intermittent flood and that without intermittent flood, there are significant variances in the other.
