The results showed: from pith outward, the tracheid length and diameter and cell wall thickness of Taxodium ascendens wood with or without intermittent flood all increased.
结果表明:间歇性淹水对池杉木材管胞形态的径向变异规律无影响,即不论有无间歇性淹水,池杉木材管胞长度、直径、壁厚,皆是自髓心向外呈增加趋势。
The tracheid diameter and the thickness of cell wall increase from pith to bark.
管胞直径、胞壁厚度自髓心向外增加。
The thickness-diameter ratio of culm, stem diameter, culm wall thickness and pith diameter were significantly correlated with stem strength.
结果表明小麦茎秆强度与厚径比、壁厚均呈极显著正相关,与髓腔直径呈极显著负相关。
