Since roots and stems have quite different vascular anatomies, major vascular changes take place at this point. Root-crown temperature has been found to affect plant growth and physiology in a number of ways. Root crowns need to be exposed and 'breathe'; this is one way that some plants take in oxygen. A number of pests and diseases affect specifically this part of the plant, including root-crown rot (or root-crown fungus)〔(Root and Crown Rots ). University of Wisconsin Garden Facts.〕 and a number of species of root-crown weevil. The root crown area usually appears swollen, tapered, constricted or very thin - as well as a combination of these. The area of the root crown is usually located around or at the soil level and can be vaguely or clearly apparent.〔http://www.cactus-art.biz/note-book/Dictionary/Dictionary_R/dictionary_root_crown.htm〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Root crown」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
