There are some sclerenchymatous cells outside the phloem of each vascular bundle to increase the supporting force of the petiole .

维管束鞘：在被子植物叶中，围绕维管束的通常是一层薄壁或厚壁细胞。

Bundle sheath the ring of parenchymatous or sclerenchymatous tissue , usually one cell thick , that surrounds the vascular bundle in an angiosperm leaf .

与淹水条件相比，旱作条件下杂交稻根通气组织形成较迟，常规粳稻根皮层厚壁细胞排列较疏松。

Compared with inundatory condition , aerobic condition retarded the formation of aerenchyma of hybrid rice roots and made the cortex sclerenchymatous cells array loosely in conventional japonica root .

厚壁细胞和薄壁细胞的细胞壁厚度减小，双折射也降低，并且细胞壁的分层现象变得不明显。

Reductions of cell wall thickness and birefringence were observed in both fiber ( sclerenchyma ) and parenchymal cells , together with blurring of the wall 's layered structures .

主根深入土壤，侧根发达；并对各种黄连根茎厚壁细胞的有无及存在部位以及生长环境进行了讨论。

Such as main root went deep into soil , lateral root and mechanical tissue of stem was well developed . The mechanical tissue of rhizoma and ecological environment of various species of Coptis are discussed .

强株系CTV-3侵染墨西哥酸橙后，脉明明显的区域，有63%的维管束鞘厚壁组织细胞退化，脉明不明显的区域仅有34%～48%的退化；

A severe CTV isolate , CTV-3 infected Mexican lime had 63 % of vascular bundle sheath cell degraded at the prominent vein clearing area and 34 % - 48 % in the less prominent areas .

厚壁组织细胞是一种常见的支持细胞类型。

Sclerenchyma cells are a more common type of supporting cell .

纤维：一种厚壁组织细胞，通常与维管组织有关。

Fiber A form of SCLERENCHYMA cell that is often found associated with vascular tissue .

在厚壁休眠细胞如藻菌纲的厚孢子或接合子中明显的几层是常常能看见的。

Distinct layers are often visible in thick-walled resting cells such as chlamydospores or zygotes of Phycomycetes .

枣实生苗一年生枝条韧皮部富含厚壁纤维细胞，皮层和髓心中分布有各种内含物细胞。

Thick-wall fibrous cell is rich in the phloem of the one-year-old seedlings . Various content cells are distributed in cortex and pith .

因此，小麦品种抗扩展性的机制之一是靠预先形成的组织结构&厚壁组织和细胞壁厚度等解剖特征来实现的。

Therefore one of the mechanism of the scab resistant to augmentability of varieties of wheat was the preformed tissue structure & cortical sclerenchyma and cortical sclerenchyma cell wall thickness etc.

化石中的植物较小，树干中其他部分也出现了具有较厚细胞壁的细胞，这暗示这木本的出现是植物为了更加有效地从土壤中汲取水分。

The plants'small size , as well as the presence of thick-walled cells elsewhere in the stems , suggests that wood evolved to efficiently transport water from the soil into the plant .

有些初生树脂道的鞘细胞为薄壁的生活细胞，而有些初生树脂道和次生树脂道的鞘细胞为厚壁的死细胞。

Surrounding the epithelium there were usually one or two layered sheath cells , which were parenchyma cells in some primary resin ducts and dead cells with thick walls in other primary resin ducts and secondary resin ducts .

茎横切面显微观察，茎内厚壁组织发达，细胞排列紧密；

Under microscopical examination , closely arranged cells and well developed sclerenchyma tissue were found in cross sections of the stem .

在实验家兔的皮损刮屑中可见菌丝及类似厚壁孢子的肿胀细胞。

Hyphae and swollen cells resembling chlamydospores were observed in the scrapings of skin lesion of the experimental infection of the rabbit .

乙烯利、多效哩处理抑制了茎叶组织结构中的厚角细胞和厚壁细胞的发生与发育，但促进了狗牙根茎维管组织的发育；

The ethephon and paclobutrazol treatments repressed growth of the epidermal sclerenchyma cells .
