The pith of this stemlike stele appears rather strongly like collenchyma tissue . 茎状中柱的髓显得颇强健，像厚角组织。
2.
Collenchyma cells have thick walls that are especially developed at the corners of the cell . 厚角组织细胞尤其在细胞的各个角上具有厚壁。
3.
Collenchyma a specialized type of parenchyma , usually located just beneath the epidermis , that functions as supporting tissue 厚角组织：一种特殊类型的薄壁组织，通常位于表皮的下方，起支持作用。
4.
Collenchyma is the first strengthening tissue to be formed in young plants and is able to expand as the yound tissues continue development 厚角组织的有较强的机械强度，并且能够随着周围细胞的延伸而扩展。
5.
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 其菌体主要分布在根部厚壁组织的细胞间隙，茎部厚角组织的细胞间隙、维管束等组织的细胞间隙、叶片的气孔器附近、上下表皮细胞间隙、厚角组织细胞间隙以及内皮层组织细胞间隙等。
