基本分生组织

分枝列当茎的初生分生组织由原表皮、原形成层和基本分生组织组成。

Primary meristem of stem is composed of protoderm , procambium and ground meristem .

而维管束鞘细胞则来源于基本分生组织，属于基本组织的范畴，与维管束不同源。

The vascular bundle cells stemmed from ground meristem , belonging to ground tissue and differing from vascular bundle sheaths in origin .

初生分生组织由原表皮、基本分生组织和原形成层组成。初生分生组织的衍生细胞分化形成茎的初生结构，包括表皮、皮层、维管束、髓和髓射线。

The primary structure consisted of epidermis , cortex , vascular system , pith and pith ray .

The development of oil and mucilage cells in the stem and leaf of Cinnamomum longepaniculatum were studied with the help of method of semithin section .

心形胚继续发育形成鱼雷期胚时，原表皮、基本分生组织和原形成层的分化已经比较明显。

When the mature heart-shape embryo proceeds with the development that leads to the formation of the torpedo stage , the procuticle , meristematic tissue and protocambium have differentiated obviously .

在未出现油细胞以前，上述器官的基本分生组织和原分生组织中，难以区分油细胞的原始细胞与周围细胞。

Before the oil cells can be distinguished , it is difficult to tell oil cell initials from surrounding cells in the primordial meristem and ground meristem of leaf and shoot .
