| 1. | Heat sum is a useful measure of the onset of meristematic activity buds in deciduous and fruit trees .
积热也是测定落叶树和果树芽分生组织活动的有效手段。 |
| 2. | Clonal propagation of plants by runners is based on meristematic activity of the differentiated cells of the plants .
植物通过长匐茎的无性繁殖基于植株分化细胞的分生活性 |
| 3. | The paper discussed the change rule of meristematic nuclei and their relation with the intercellular rhizobia
本文还讨论了分生细胞核的变化规律及其与胞间根瘤菌存在的关系。 |
| 4. | It may develop by thickening of the secondary walls of parenchyma cells , or it may arise directly from meristematic cells
它们可能由薄壁组织的细胞壁次生加厚而成，也可能直接来自于分生组织细胞。 |
| 5. | 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。 |
| 6. | The vascular cambium extends to form a complete ring of meristematic tissue around the stem , the separate vascular bundles being linked by interfascicular cambium
维管形成层向两侧延伸直至形成一个茎内的分生组织环，各个维管束被束间形成层联系在一起。 |
| 7. | Competence a characteristic of embryonic cells and meristematic cells whereby they have the potential to differentiate into any of several different types of cell
感受态：胚胎细胞和分生组织细胞具有的一种生理状态，它们可以具有分化为各种类型细胞的能力。 |
| 8. | Proplastid a self - duplicating undifferentiated plastid , about 0 . 5 - 1 m in diameter and found in the meristematic regions of plants . they grow and develop into plastids of different types
前质体：能够自我复制的没有分化的质体，直径约0 . 5 - 1微米，发现于植物分生组织区域。它们生长发育为不同类型的质体。 |
| 9. | The results showed that there was a great deal of microfilaments in root meristematic cells , there was a few microfilaments in cotton callus and abnormal plantlets ; by alignment of peac17 with cotton actin
因此推测，微丝在细胞中的这种分布可能与愈伤组织不能继续诱导出正常的植株而诱导出畸形苗有关。 |
| 10. | The root point thereforecan grow , is by the root point growing point ( meristematic tissue ) thecell can unceasingly split produces the new cell , as well as the newcell unceasingly elongates result
根尖之所以能够生长，是由根尖生长点（分生组织）的细胞能够不断地分裂产生新细胞，以及新细胞不断伸长的结果。 |
