Potassium antimonate was employed to ultrastructurally locate calcium ions in seminal root apical meristematic cells of maize seedings subjected to flooding stress.
采用焦锑酸钾沉淀法,对遭受淹水胁迫的玉米幼苗初生根根尖分生细胞内钙离子分布变化情况进行了电镜细胞化学观察。
Root growth is mainly determined by cell division and subsequent elongation in the root apical area. Components regulating cell division in root meristematic cells are largely unknown.
根的生长主要取决于根尖区的细胞分裂和伸长,而调控根尖分生组织细胞分裂的成分很大程度上是未知的。
Calyptogen a layer of meristematic cells covering the root apical meristem in some plants (e. g. grasses) that gives rise to and maintains the root cap.
根冠原:在一些植物中覆盖根顶端分生组织的一层具有分生能力的细胞,根冠原可以产生和维持根冠。
