n.[植]形成層；新生組織

The vascular cambium is located between the xylem and the phloem. 維管形成層位于木韌之間。

The base of scoin is cut diagonally to expose a large oval of cambium. 接穗的基部被切成斜形，暴露出橢圓形的大圈形成層。

The vascular cambium extends to form a complete ring of meristematic tissue around the stem, the separate vascular bundles being linked by interfascicular cambium. 維管形成層向兩側(cè)延伸直至形成一個(gè)莖內(nèi)的分生組織環(huán)，各個(gè)維管束被束間形成層聯(lián)系在一起。
