中柱鞘

Stele The vascular tissue and associated parenchyma tissue and the surrounding pericycle and endodermis of a stem or root.

中柱：包括根或茎的维管组织及相关薄壁组织，若有维管束鞘和内皮包被则这二者也属于中柱结构。

Rice lateral root primordia initiated only from the pericycle cells adjacent to the phloem poles, indicating that initiation of rice lateral root primordia had specific cell type pattern.

3水稻侧根原基起始具有严格的细胞位置效应，只有与韧皮部极直接相邻的中柱鞘细胞才能分化形成侧根原基。

Pekinensis . IAA at concentration of 0.4-1. 0 mg/L in solid MS medium incited many adventitious roots on hypocotyl segments. The earliest anatomic changes were observed on cut surface of hypocotyl segments under optical microscope 24 hours after IAA treatment: cytoplasmic and nuclear density became higher in a few of parenchytmatous cells adjacent to phloem in tissue of pericycle, followed by cell divisions.

在生长素诱导24h后，可借助显微切片观察到下胚轴切面附近明显的解剖学变化：首先是中柱鞘内靠近韧皮部的薄壁细胞的细胞质与细胞核变浓，染色加深，部分细胞分裂；随后是分裂的细胞团增大，逐渐形成根原基并分化出根冠。

The dominant phytoplankton species outside and inside the bay were Cylindrotheca closterium and Skeletonema costatum, while the samples in the harbor had Skeletonema costatum, Eucampia zodiacus, and Chaetoceros curvisetus as the dominant species.

The secondary growth mainly depend on the activities of vascular cambium and cork cambium; the cork cambium originates from pericyclic cells.

次生生长主要是由维管形成层和木栓形成层的活动完成，木栓形成层起源于中柱鞘细胞。
