- Both xylem and phloem form a continuous branched system in the whole plant body. 木质部和韧皮部在植物体内构成一个连续的分支系统。
- Haplostele A type of protostele having a solid strand of stele with the xylem on the inside encircled by phloem, pericycle, and endodermis. 单中柱:原生中柱的一种类型,是由韧皮部、中柱鞘和内皮层包围着内方的木质部构成的实心中柱。
- Protophloem The first-formed PRIMARY PHLOEM, differentiated from the procambium in the region just behind the meristem. 原生韧皮部:最早形成的初生韧皮部,由位于分生组织中的原形成层分化而来。
- Intrafascicular cambium (fascicular cambium) The part of the VASCULAR CAMBIUM within the vascular between the xylem and phloem. 束中形成层:是位于木质部和韧皮部构成的维管束内的一部分维管形成层。

- The adventitious buds can be developed in the crossed area of both cork cambium and phloem ray inside the root. 宿根上的不定芽发生于韧皮射线与木栓形成层交叉的区域。
- The correlation between the reducing sugar content in phloem and xylem and the ratio of damaged trees was not close. 不同杨树品系韧皮部和木质部的还原糖含量与被害株率没有相关性。
- The stele includes all primary tissues derived from the procambium consists of pericycle,phloem and xylem. 中柱包括从原形成层衍生而来的全部初生组织,由中柱鞘、韧质部和木质部组成。
- More secondary phloem than secondary xylem in carrot Parenchyma predominates in vascular tissues. 在胡萝卜根,薄壁细胞在维管组织中占主导地位,次生韧皮部比次生木质部更发达。
- 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. 如在榉木或橡木中,相同的木栓形成层年复一年的活动,那么树皮是光滑的,并且仅形成韧皮部的外方组织,主要是木栓(软木)。
