分生区(division zone)：又称生长锥，呈圆锥状，具很强的分生能力。形成根的表皮、皮层和中柱。 3.伸长区(elongation zone)：位于分生区上方，此处多数细胞已逐渐停止分裂，细胞显著沿根的长轴方向延伸，因此称为伸长区。 4.

In order to simulate the growth of plant stem,plant stem and branches were divided into fine grit,and the plant growth process was iterated by dividing the stem into tertiary structure of meristematic zone,elongation zone,maturation zone. The parametric L-systems theories were applied in simulating the geometry shape of the plant.
为真实仿真植物茎生长过程,对植物茎以及分枝进行更细粒度划分,把茎的生长按分生区、伸长区、成熟区三级结构划分依次迭代,结合参数L系统仿真植物的形态几何结构,达到了良好的效果。

Cells of middle elongation zone and root hair zone were also labelled by many gold particles.
伸长区中部及根毛区细胞也有较多的金颗粒标记。
The results of GUS staining showed that NPC2 expressed mainly in meristematic zone, elongation zone and vascular tissue of maturation zone of root tip;
GUS染色显示NPC2在根中主要是在根尖分生区和伸长区表达，在成熟区主要是在维管组织中表达；
Improvement of elongation of joint is related to weaker cool deformation degree of heat affect zone (HAZ) and uniformity of strength and stress level between weld and base metal.
接头延伸率的改善同热影响区冷变形程度的减弱及焊缝强度、应力水平同母材趋于一致有很大关系。
