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。

The results showed that Hyphae, conidiophore, conidium and chlamydospore of biocontrol strains ZK7 and IPC were found in the rhizoplane, Hyphae of ZK7 and IPC penetrated epidermal cells to deep cortical cells but not in phloem tissue and xylem vessels, biocontrol strains ZK7 and IPC also crossed and even grew within epidermal and conical cell walls without any visible alterations of the plant cell.

生防菌ZK7和IPC菌株能以菌丝方式稳定定殖于烟草根表的根冠区、伸长区、根毛区、成熟区等不同部位，而在根内的定殖仅局限于根表皮层较深的细胞组织，不能侵入烟草根部的韧皮部和木质部组织。

The results displayed the symplasmic isolation of sieve element/companion cell complex from the surrounding parenchyma cells, and suggest that the photoassimilate unloading from phloem follows an apoplasmic pathway and must be facilitated via the sugar transporters.

由此可见，苹果果实韧皮部组织同周围薄壁组织存在共质体隔离，同化物必须通过糖转运蛋白的介导从筛分子以跨越质膜的方式卸出到质外空间，然后再装载到周围薄壁细胞中。

Stylets of the aphids on the stems could reach the phloem with less probes and shorter time compared to those of aphids on other two parts.And no significant differences were found in feeding behaviors among aphids on three plant parts once sustained ingestion started in the phloem.

相对于其它两个部位，甘蓝蚜的口针在花茎上用较少的刺探次数和较短的时间到达韧皮部；一旦口针进入韧皮部持续吸食阶段，蚜虫在三个部位的取食行为没有太大的差异。

The results showed that the tensile strength of kenaf phloem bundle fiber had regular transverse and longitudinal distribution patterns along with the changes of plant size, plant height and phloem bundle layer.

结果表明，红麻韧皮部束纤维抗拉强度随着植株大小、植株高度及束纤维不同层次的变化在横向和纵向分布上呈现一定的变化规律，推测与红麻纤维发育期间的外界环境条件有密切关系。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
