韧皮部

The secondary phloem is larger than the secondary xylem in the Heracleum , which is the typical storing root .

根据独活属植物根的次生韧皮部远比次生木质部发达的特点，确定独活属植物的根是典型的贮藏型根。

Phloem is an important part of vascular system and plays a key role in material transportation, signal transmission, mechanical support and defense reaction.

韧皮部是维管系统的重要组成部分，在物质运输、信息传递、机械支持以及防御作用中发挥重要作用。

In vascular plants, the xylem and phloem serve to translocate such substances.

维管植物的木质部和韧皮部主要进行对这类物质进行运输。

The endophytic fungi were existed in the local cells of cork and secondary phloem in the root of E.fordii .

内生真菌只在一定区域的皮层和次生韧皮部细胞中分布。

ResultsAbove-mentioned constituent contents had little difference, and they were distributed in phloem.

结果刺五加药材中根、根茎和茎中各种成分含量相近，且主要分布在韧皮部。

There are also fibers,and parenchymatous packing tissue in the phloem.

韧皮部中还有韧皮纤维以及薄壁组织细胞。

It consists principally of XYLEM and PHLOEM (water and food-conducting tissues respectively), and also contains strengthening tissue and packing tissue.

它主要包括木质部和韧皮部，还含有机械组织和填充组织。

ConclusionIt is reasonable that root, rhizome and stem as well as phloem and xylem are can be used together.

结论不同用药部位根、根茎和茎及不同组织韧皮部和木质部可共同入药具合理性。

Phloem Plant vascular tissue in which food is transported from areas where it is made to where it is needed or stored.

韧皮部：植物维管组织中将有机养料从一个区域输送至必需或贮存部位的结构。

Ten secondary metabolites in phloem of different strains of poplars were extracted by different chemical methods and their contents were determined.

摘要通过不同化学方法提取并分析了不同品系杨树韧皮部10种次生代谢产物的含量及含量差别，研究了不同制样方法对单宁、酚类及酚酸产物含量提取结果的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
