Thickness of upper and lower epidermis of leaves, width of xylem and phloem of annual and biennial branches, ratio of late wood to early wood, periderm thickness of biennial branches, and length of xylem ray present decreasing trends with latitude ascending ; while ratio of palisade tissue to spongy tissue, epidermis thickness of annual branches, and cortex thickness of biennial branches show unobvious variations with latitude increasing
葉的上下表皮厚度、 1和2年生枝木質部及韌皮部寬度、晚材早材比值、 2年生枝的周皮厚度、木射線長等均隨緯度升高而呈下降趨勢；而葉的柵欄組織和海綿組織比值、 1年生枝表皮厚度、 2年生皮層厚度等解剖結構隨緯度變化沒有明顯規律。 -
If the same phellogen functions from year to year, as in beech and oak, then the bark is smooth and consists only of tissue external to the phloem, mainly cork
如在櫸木或橡木中，相同的木栓形成層年復一年的活動，那麼樹皮是光滑的，並且僅形成韌皮部的外方組織，主要是木栓（軟木） 。 -
It consists principally of xylem and phloem ( water and food - conducting tissues respectively ), and also contains strengthening tissue ( sclerenchyma ) and packing tissue ( parenchyma )
它主要包括木質部和韌皮部（分別運輸水分和養料） ，還含有機械組織（厚壁組織）和填充組織（薄壁組織） 。 -
In nonwoody plants it is the only food - conducting tissue, but in mature plants with secondary growth this function is taken over by the secondary phloem
在尚未木質化的植物中，它是唯一的輸送有機營養的組織，但在具有次生生長的成熟植物體中，該功能由次生韌皮部行使。 -
For amorpha fruticosa linn., there exists epidermal hair on the upper epidermis, some macro ventilating pit in the spongy tissue, many crystal cells in the phloem of the leaf and around vascular bundles
紫穗槐葉的上表皮有表皮毛，海綿組織局部有大型通氣孔，在葉的主脈韌皮部處和葉柄維管束內外都含有許多含晶細胞。 -
The result showed that cu, zn, fe, mn mostly distributing in the cortex, secondly distributing in the xylem or the marrow, the content is lower in the phloem of rhizome tissue on the cultivated rheum
結果表明，種植大黃根莖中銅、鋅、鐵、錳等元素主要分佈在皮層，其次是木質部或髓部，元素含量較低的是韌皮部。 -
The rhizome of cultivated rheum in qunjia of qinghai province, was picked broke into cortex, phloem, xylem and marrow, the content of cu, zn, fe, mn, co, ni elements of the every tissue was analyzed by atom absorb spectrum
採集青海群加地區種植大黃根莖，分為皮層、韌皮部、木質部和髓部等四部分，採用原子吸收光譜法分別測試了其不同組織中銅、鋅、鐵、錳、鉆、鎳等元素含量。 -
Roots also differ from roots in the arrangement of xylem and phloem, having a solid central strand of vascular tissue rather than a hollow cylinder of conducting tissue
根和莖不同，它無葉綠素，沒有芽和葉，木質部和韌皮部的排列順序也不同，其內部為實心的維管組織，而莖的內部為中空的圓柱形輸導組織。
