NKT4 was mainly expressed in main roots and lateral roots and little in leaves in Nicotiana tabacum.

基因表达分析表明，NKT4主要在烟草主根和侧根中表达，在烟草叶中也有少量表达。

It was proved that the root colonization dynamics and density of rhizobium population played an important role in competitive nodulation.

并且发现在此区段的主根瘤发光比例高达90％以上，显著大于此区根段的侧根瘤发光比例，从而说明种子表面的接种根瘤菌主要是沿着主根的伸长而向下扩散定殖。

The main results were as follows:An appropriate concentration of ethephon sprayed on leaves of peanut made stems and branchs height shorter,but more branches;The fresh weight and dry weight per unit of leaf area and per plant increased;It optimized some physiological and biochemical characteristics in the leaves.It was showed that the ethephon increased obviously the contents of protein and chlorophyll and the activity of SOD and POD in the leaves,and improved the rates of photosynthesis and transpiration of the leaves,and increased the activity of the roots,but decreased the content of MDA in the leaves;It improved the quantity of pods,the percentage of plumy pods and the peanut yield.

结果表明：喷施适宜浓度的乙烯利可使植株相对矮化，抑制花生地上部分的生长，使主茎和分枝长比对照短，但分枝数较多；提高单位叶面积鲜重、干重以及植株鲜重、干重；优化花生植株的生理生化特性，表现为显著提高了花生叶片的蛋白质含量和叶绿素含量及SOD和POD活性，增强了花生叶片的光合速率和蒸腾速率，增强了主根活力，降低了花生叶片的丙二醛和可溶性糖含量；提高植株的单株结荚数、饱果率和产量。

Seedlings under light absorbed more rutin than those in the dark at rutin concentrations of 60-80 μg/mL and absorbed less rurin at concentrations lower than 40 μg/mL or near 100 μg/mL. IAA (＞0.1 μg/mL) treatment promoted rutin accumulation and inhibited elongation of shoot axis and primary roots.

当培养基中的芦丁浓度为60～80 μg/mL时，光照下的幼苗比暗处理的幼苗在胚轴中积累更多的芦丁；而芦丁浓度为40μg/mL以下和接近100μg/mL时幼苗在光照下累积的芦丁较暗处理的幼苗更少。0.1μg/mL以上的IAA促进芦丁的累积而进一步抑制幼苗胚轴和主根的伸长。

The Gaoshawo provenience showed a better growth status in plain region by comparing with the Hangjinqi provenience of the seedling physiological characterization and the medicinal composition content of the annual root.

对一年生直播甘草的分析表明，主根长度与甘草苷含量达到显著正相关水平，根重与甘草酸和甘草苷含量均呈一定程度的正相关；甘草苷含量与甘草酸含量呈极显著正相关关系，说明甘草酸和甘草苷的积累速度具有协同性。

Anatomical structure and the content of barbloin in primary roots of Pulsatilla chinensis were studied by means of anatomy and histochemical localization.

利用解剖学和组织化学的方法，研究了野生和栽培白头翁主根的解剖结构和皂苷组织化学定位。

The root system of the soybean consists of a taproot formed by the radicle.

大豆的根系包括由胚根形成的主根。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
