查询词典 pollen

On the plus side, wind dilutes and scatters air pollutants, and carries pollen.

从好处来说，风能稀释和驱散空气中的污染物质，传播花粉。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.

结果表明在中期I阶段，这些杂种一代的近缘染色体联会变化很大，每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等，甚至在某些花粉母细胞中，还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体；在后期I时，所有的二价体分离，同时多数单价体也分离，分离的二价体和分离的单价体都移向两极，从而形成两组染色体；因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现，从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型，如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

What will happen if the pollen of a transgenic plant containing some kind of drug fertilizes a nearby edible crop?

侵蚀， 如果含有药物制剂的转基因植物花粉对邻近可食用作物授粉以后会怎样？

When pollen maturating,many small calcium precipitates distributed in its cytoplasm,especially in nucleus.

随着二胞花粉的大液泡完全消失，其细胞质中又出现了许多钙颗粒。

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.

本试验研究结果表明：60 Coγ射线辐照小豆种子的半致死剂量平均为 3 89Gy ，且M1生长初期叶片性状有明显的叶面缺刻、叶色缺绿、叶形不对称、叶缘卷曲、花叶、黄叶等致变现象，各种畸型叶出现频率与辐照剂量大小有关；M1根尖细胞中有多种染色体畸变类型，以染色体桥和断片频率较高，辐照剂量在 40 0Gy以上时根尖细胞异常率达 1 0 %以上；植株花粉育性与辐照剂量呈极显著负相关，京农 2号植株花粉育性达 5 0 %时的辐照剂量为 3 78Gy。

Space Distribution of Pollen at Different Pollinating Time

不同时间赶粉花粉的空间分布

In more ancient times flowers were self pollinating not requiring bees in the dance to move pollen from flower to flower.

在更远古的时代，花朵可以自我授粉而并不需要蜜蜂。

They were never out of the sound of some purling weir, whose buzz accompanied their own murmuring, while the beams of the sun, almost as horizontal as the mead itself, formed a pollen of radiance over the landscape.

他们所到之处，耳边都是潺潺的流水声，水声同他们的喁喁低语交织在一起，而太阳的光线，差不多已经和草场平行，为四周的景色罩上了一层花粉似的光辉。

Bee pollen rejuvenates your body, stimulates organs and glands, enhances vitality, and brings about a longer life span.

蜂花粉科教兴国你的身体，激发器官和腺体，增强活力，带来了更长的寿命。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
