查询词典 shoot apex

Regeneration frequency varied obviously with genotypes,suggesting that the genotype is one of the important factors to the regeneration of shoot apex.

不同基因型的茎尖再生频率有很大差异，说明基因型是影响茎尖再生的一个重要因素。

Another importantcause of upper leaf necrosis is leaf enclosure/overlap on the shoot apex.

另一个导致 ULN 的病因是生长点发育被畸形叶片阻止。

Immature inflorescence, shoot apex and immature embryo were ideal explants suitable for further transformation study.

以幼穗、茎尖和未成熟胚作外植体比较理想，可用于进一步的转化研究。

In this study, the system of cotton shoot apex transformation has been established. Upland cotton genome was transformed with rol genes by Agrobacertium mediated transformation.

本研究建立了高效的棉花茎尖转化再生体系，通过农杆菌介导法将rol基因导入陆地棉基因组中，获得了生根能力加强的棉花转基因株系。

Factors affecting transformation of shoot apex mediated by Agrobacterium tumefacien were also optimized.

对农杆菌介导高粱茎尖转化的因子进行了优化，获得较高转化频率的条件为：茎尖预培养时间3D，在OD600值为0.5农杆菌菌液中感染10MIN，共培养3D。

This suggests that shoot apex is most sensitive to water stress and the ~(14)C-photoassimile distribution likely shifts from above-ground to root, being benefit to maintaining root growth and tolerance to water stress.

这表明茎尖对水分胁迫非常敏感，同化物向茎尖的运输受到抑制，运积重心由地上部转到地下部，从而有利于保持根系在胁迫条件下的生长，提高植物的抗旱性。

In comprehensive concerning of all above,it is suggested that theincrease of zinc content in shoot apex may involved in IAA synthesis in thispart,which is more likely to be an orignal signal that plays a critical role inthe regulation of root ferric reductase activity of iron-deficientdicotyledonous plants.

综上所述，缺铁胁迫条件下，根系铁含量的降低导致根系锌含量的积累，从而使茎尖的锌含量增加并有可能促进地上部IAA的增加。在双子叶植物中，IAA可能是调节缺铁根系〓还原酶活性的初始信号物质。

The pattern of IAA change in shoot apex may havea direct relationship with the root ferric reductase activity of deficient beanplant.

这种茎尖IAA合成和输出的增加可能与缺铁菜豆植株根系〓还原酶活性的调节有直接关系。

Removal of the shoot apex and leaf wounding did not show any influences on nitrogen uptake by plant, but increased nicotine production per unit nitrogen.

切除顶芽和叶面损伤对烟株体内的氮浓度及吸氮量均无显著影响，但显著提高了烟株体内单位氮素产生烟碱的能力。

Effects of removal of the shoot apex and leaf wounding on nitrogen uptake and nicotine production were studied with tobacco plants grown in sand or hydroponic medium under the controlled conditions.

采用砂培和营养液培养方法，研究了在营养生长阶段切除顶芽和叶片损伤对烟株生长、体内烟碱浓度、氮浓度及吸氮量的影响。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
