木质部的

After vascular cambium cells divide, the progeny cells on the interior side become xylem parental cell.

维管形成层细胞分裂后，在内侧分裂出来的细胞成为木质部的母细胞。

With age adding, the area ratio of phloem and xylem decreases in Ch.smyrnioides . Differentiation of vascular cambium is active in 3～4 years root.

不同年龄的明党参主根随根龄的增加，韧皮部与木质部的比例减小，维管形成层在三至四年生根中活动最旺盛。

High-pressure trunk-injection of iron fertilizer was reported to be effective to correct chlorosis, but the mechanism involved was unknown.

结果表明，铁肥树干强力高压注射，主要以二价铁(Fe2+)沿中央木质部的导管运输，大部分向下运输，使铁在根中大量贮存；向上运输较少，运输速度为每小时数百厘米，矫正缺铁失绿症的速度比根系输液慢，但由于根中贮存大量的铁，持效期较长。

On the evolution of secondary xylum and its significance in plant phylogeny.

次生木质部的进化与植物系统发育的关系。

Various mechanisms have been suggested for the nature of root pressure.

在植物弱蒸腾情况下，木质部的水分处于正压状态，这种压力叫根压。

If timber poles are used, the bark can be peeled off the tops to expose the light colored sapwood

如用圆木杆，可削去顶端树皮，露出木质部的明亮色泽。

The exterior of root system of alfalfa in adult period hasn't velamen. The polysaccharide in the interior of root system lies in partial secondary phloem and xylem ray of secondary xylem, which doesn't distribute uniformity.

这与苜蓿有差别，苜蓿成株根系外侧没有"根被"，且根系内部多糖存在于部分次生韧皮部和次生木质部的木质射线中，分布不均匀。

Darcy\'s law was first successfully applied in analyzing water conductivity characteristics of xylem on above basis.

在此基础上，首次成功地将Darcy定律应用于树木木质部的导水特征分析。

The biomass of trees and the calcium content and accumulation of the cortex and the xylem were studied in this paper.

对幼果期矮化富士苹果树体各器官及其皮层、木质部的生物量、钙含量和钙累积量进行了研究。

Bicollateral bundle The arrangement of tissues in the vascular bundles in which the phloem is situated on both sides of the xylem.
