| 1. | They are located in tissues (the apical meristems) at the growing points of roots and stems . 它们位于根和茎的生长点组织(顶端分生组织)中。 |
| 2. | It is implicated in the uptake of calcium , the development of apical meristems , and pollen germination 它还与钙的吸收,顶端分生组织发育和花粉萌发有关。 |
| 3. | Primary growth growth derived solely from meristems present in the embryo , i . e . apical meristems 初生生长:指完全起源于胚芽分生组织即顶端分生组织的生长。 |
| 4. | The term is used particularly in relation to a part of the apical meristem that later differentiates further 该名词也用于指随后进一步发育的顶端分生组织。 |
| 5. | Quiescent center a group of cells in the center of the apical meristem in which mitotic divisions are rate or absent 静止中心:在根的顶端分生组织中心区域的一些细胞,它们几乎不进行有丝分裂。 |
| 6. | 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。 |
| 7. | Ground meristem the central region of the apical meristem from which the ground tissues of pith , cortex , medullary rays , and mesophyll differentiate . in root meristem it is also called periblem 基本分生组织:位于顶端分生组织的中部,髓、皮层、髓射线以及叶肉这些基本组织均是由基本分生组织分化而成。根部分生组织也称为皮层原。 |
| 8. | L . virgaurea and l . sagitta were guerrilla clonal plant of perennial herb . 2 . in the process of clonal growth , each rhizome only developed a ramet and there was no net or linear clonal growth form 在克隆生长的过程中,黄帚橐吾、箭叶橐吾每个根状茎在形成一个分株便失去顶端分生组织,不产生网状和直线型分枝,作者将其命名为游击合轴型。 |
| 9. | Flowering reversion did n ' t occur in plants treated with more than 19 photoperiods , which perhaps is due to sufficient number of floral determination cells in the meristem and the floral determination of the plants is complete 19个以上的光周期数处理的毕氏海蓬子未发生成花逆转,这可能与顶端分生组织内完成成花决定的细胞数目多,成花决定完成彻底有关。 |
| 10. | The best time to collect the materials for cloning is discussed in this paper , which is from the end of may to the beginning of june each year . it means there is only a week for the materials to transit from apex dividing tissue to flower inflorescence , but still a little change with temperature every year 实验探讨了克隆成花计时基因最佳的取材时间是,每年的5月末到6月初,顶端分生组织向花原基转变时的一个星期内集中进行,具体时间随每年温度变化做适当调整。 |
