您要查找的是不是:
- There is a little idioblasts in the phloem. 葉脈維管束中韌皮部都具有異細胞存在。
- The vascular cambium is located between the xylem and the phloem. 維管形成層位於木韌之間。
- Primary phloem PHLOEM derived from the procambium in the young plant. 初生韌皮部:指幼嫩植物中來源於原形成層的韌皮部。
- A root-like structure lacking conductive tissues (xylem and phloem). 無輸導組織(木質部和韌皮部)的根狀結構。
- The secondary phloem consisted of sieve cells and phloem parenchymas. 根的次生韌皮部則由篩胞和韌皮薄壁細胞組成。
- In vascular plants, the xylem and phloem serve to translocate such substances. 維管植物的木質部和韌皮部主要進行對這類物質進行運輸。
- Comparative anatomy of the secondary phloem of the stem in Cephalotaxus. 三尖杉屬植物莖次生韌皮部的比較研究.
- Any of various vascular plants, including seed plants and ferns, having a conducting system of xylem and phloem. 導(維)管植物任何種類的維管植物,包括種子植物和蕨類植物,具有木質部和韌皮部導管系統
- Sap 1. The solution of mineral salts and sugars that is found in xylem and phloem vessels and oozes out of cut stems. 樹液:1.;是植物木質部與韌皮部管狀分子中存在的含多種無機鹽與碳水化合物的混和溶液,可以從植物莖上的切口處滲出。
- Both xylem and phloem form a continuous branched system in the whole plant body. 木質部和韌皮部在植物體內構成一個連續的分支系統。
- Haplostele A type of protostele having a solid strand of stele with the xylem on the inside encircled by phloem, pericycle, and endodermis. 單中柱:原生中柱的一種類型,是由韌皮部、中柱鞘和內皮層包圍著內方的木質部構成的實心中柱。
- Protophloem The first-formed PRIMARY PHLOEM, differentiated from the procambium in the region just behind the meristem. 原生韌皮部:最早形成的初生韌皮部,由位於分生組織中的原形成層分化而來。
- Intrafascicular cambium (fascicular cambium) The part of the VASCULAR CAMBIUM within the vascular between the xylem and phloem. 束中形成層:是位於木質部和韌皮部構成的維管束內的一部分維管形成層。
- Phloem elements and adjacent tissues are the principal feeding sites for most aphids. 韌皮部及其鄰近組織是大多數蚜蟲的主要取食部位。
- The adventitious buds can be developed in the crossed area of both cork cambium and phloem ray inside the root. 宿根上的不定芽發生於韌皮射線與木栓形成層交叉的區域。
- The correlation between the reducing sugar content in phloem and xylem and the ratio of damaged trees was not close. 不同楊樹品系韌皮部和木質部的還原糖含量與被害株率沒有相關性。
- The stele includes all primary tissues derived from the procambium consists of pericycle,phloem and xylem. 中柱包括從原形成層衍生而來的全部初生組織,由中柱鞘、韌質部和木質部組成。
- More secondary phloem than secondary xylem in carrot Parenchyma predominates in vascular tissues. 在胡蘿蔔根,薄壁細胞在維管組織中佔主導地位,次生韌皮部比次生木質部更發達。
- 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)。
- Any of various vascular plants,including seed plants and ferns,having a conducting system of xylem and phloem. 導(維)管植物任何種類的維管植物,包括種子植物和蕨類植物,具有木質部和韌皮部導管系統
