这种细胞存在于根和芽的顶端分生组织以及在原来分裂组织基础上形成的侧生分生组织，如位于木质部和韧皮部之间的束中形成层。

Capillarity The rise or fall of liquids in narrow tubes as a result of the surface tension of the liquid, which causes the water to adhere to solid surfaces, such as soil particles or the walls of xylem vessels.

毛细现象：由液体表面张力引起的液体在细管中上升或下降的现象，毛细现象引起水和固体表面的粘合作用，例如土壤颗粒或木质部导管壁。

The results showed that the phytophagous insects in the spruce forest in Qilian Mountains exhibited obvious vertival stratification structure. According to the amounty of species of each structure, it could be divided into 6 insect communities, namely the insects community of the shrub and herbage (928 species), of the soil and root (780 species), of the tender end and needle (117 species), of the stem phloem and xylem (66 species), of the branch thin end twig shin (38 species), of the blossom and seed and fruit (14 species).

结果表明祁连山区青海云杉林中植食性昆虫具有明显的垂直分层结构，根据林分的垂直结构和昆虫寄生、取食树木组织部位可划分为6个群落，其种类由多到少依次为灌木和草本层昆虫群落（928种），土壤与根部昆虫群落（约780种），嫩梢与针叶昆虫群落（117种），树干韧皮部与木质部昆虫群落（66种）、枝梢与嫩皮昆虫群落（38种）、花与种实昆虫群落（14种）。

Tracheid An elongated xylem conducting element with oblique end walls.

管胞：具有倾斜端壁的延伸的木质部运输分子。

The root system in the cortex of the host stem has a few branches and highly simplified stele of original triarch vascular bundles. The haustrium root system, which is from the root system in the cortex of a host stem enters the vascular tissues as finger-like body from the vascular rays and then to become hyphae-like body among the vascular cells.

皮层根有少数分枝，无次生结构，中柱结构高度简化，从胚根的结构可看出其初生木质部原先是三原型的；吸器根从皮层根上发生，进入寄主维管射线中，再进入维管组织内，并形成许多丝状体。

There was no significant difference in IAA concentration in apple leaf betweencontrol plant and drought plant before the fifth day of drought,after wards with thedrought time prolonging,when soil drought leavel became severe IAA concentrationdecreased significantly.

木质部汁液和根中ABA浓度的变化趋势与叶片中ABA浓度的变化趋势相同。

Contents of Cu, Zn, Ni, Cr and Pb increased steadily in tree-rings from the heart-wood to sap-wood at both sites, reflecting the increase in the bio-availability in the Delta area during the past decades. Peaks in Cu, Zn, Ni and most obviously Cr and Pb, were found in rings formed after 1990. It was suggested that the recent increase of the heavy metals in soil and atmosphere in the Delta was the main source contributed to the elevation of the heavy metals in the pine rings.

结果表明：西樵山马尾松林地表层土壤Cu、Zn、Cd和Pb含量均超过其在广东省表层土壤环境背景值，鼎湖山马尾松林地表层土壤除Cd外其余重金属含量在背景值范围内；鼎湖山和西樵山马尾松木质部中Cu、Zn、Cr和Pb含量均呈现从心材到边材上升的分布格局，反映了珠江三角洲环境中可供植物利用的重金属在过去有了增加。

They are common in many situations, for example as gland cells and epidermal cells, and in xylem and phloem parenchyma, where they are concerned with active loading and unloading of vessels and sieve tubes.

许多情况下都有传递细胞发挥作用，例如：腺细胞和表皮细胞，还有木质部和韧皮部的薄壁细胞，该处导管和筛管的主动装填和排空都与传递细胞有关。

The annual rings of plants growing in temperate climates can be seen in crosssection as two consecutive rings of light and dark-colored xylem tissue.

在有显著季节性气候的地区中，不少植物的次生木质部在正常情况下，每年形成一轮。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
