root bundle 中文意思是什麼
root bundle
解釋
根束, 根絲-
The bacteri of strain tl2 were found to be mainly distributed in the intercellular space of sclerenchyma in the root, the intercellular space of collenchyma and vascular bundle in the stem, the stomatal apparatus, the intercellular space of epidermal cell, collenchyma and endodermis in the leaf
其菌體主要分佈在根部厚壁組織的細胞間隙，莖部厚角組織的細胞間隙、維管束等組織的細胞間隙、葉片的氣孔器附近、上下表皮細胞間隙、厚角組織細胞間隙以及內皮層組織細胞間隙等。 -
There are many adaptive changes in the two research subjects ( artemisia. songarica schrenk. and seriphidium. santolinum ( schrenk ) polijak. ) in morphology and anatomy, such as with the increase of the daily age, the root - shoots ratio increased ; the root became stronger ; the ratio of leaf volume and leaf area increased ; the volume of epidermic cell decreased ; the cut - icle and phellem layer on the surface of root thickened. stoma caved in leaf ; epidermal hair of leaf and stem well - developed, palisde tissue developed well, the cell gap decreased ; the spongy tissue disappeared ; leaf is kinds of isolateralthat is the typical xeromorphic structure ; crystal cell and fibric cell increased ; conducting tissue and mechanical tissue developed well ; bundle sheath appeared
實驗研究的兩種菊科（ compositae ）植物（準噶爾沙蒿（ artemisiasongaricaschrenk ）和沙漠絹蒿（ seriphidiumsantolinum （ schrenk ） poljak . ） ） ，形態解剖方面的變化表現為：隨日齡增加，根長/株高比值日益增大；根系逐漸發達；體積與葉面積比逐漸增大；表皮細胞體積變小；角質層增厚；根外部出現加厚的木栓層；氣孔下陷；葉、莖部的表皮毛密布，柵欄組織日益發達；而細胞間隙日漸變小；海綿組織逐漸消失；葉面結構常為典型旱生結構? ?等葉面；晶細胞及纖維細胞數目增多；輸導組織、機械組織日漸發達；具有維管束鞘等等。 -
The leaf epidermis of the two species has slight curicular and a few of stomata. their root system and vascular bundle are slim and fragile so as to be vulnerable to damage produced by changing of environment conditions
兩物種表皮角質化程度低，氣孔少，根系與維管束不發達，極易受到外界環境的影響而發育不良。
