In the BC〓F〓 and BC〓F〓 generation of Yannong15×Thinopyron intermedium hybrid, 4 octoploids which had chromosome number of 2n=56 and could form 28 bivalent at PMC MI, 14 disomic addition lines which had chromosome number of 2n=44 and could form 22 bivalent at PMC MI; three monosomic addition lines which had chromosome number 2n=43 and had the chromosome configuration of 21Ⅱ+1Ⅰ at PMC MI, 1 substitution line which had chromosome number 2n=42 and could form 21 bivalent at PMC MI were selected by observation of mitosis in root tip cell and meiosis in pollen mother cell.

在烟农15与中间偃麦草杂交的BC〓F〓和BC〓F〓代中，通过根尖有丝分裂和花粉母细胞减数分裂中期Ⅰ观察选出4个2n=56，PMC MI染色体构型为28Ⅱ的八倍体小偃麦；14个2n=44，PMC MI染色体构型为22Ⅱ的双体异附加系；3个2n=43，PMC MI染色体构型为21Ⅱ+1Ⅰ的单体异附加系；1个2n=42，PMC MI染色体构型为21Ⅱ的异代换系。

In the studies on transferring and identifying alien chro-mosomes into wheat,the combined use of mitotic and meioticchromosome N-banding is also successfully practiced in deter-mination of T.durum-H.villosa amphipoid,five wheatalien disomic additions with H.villosa chromosomes,〓〓,alien sulstitution line with chromosome 〓 andsome translocation lines.

在外源染色体导入、鉴定研究中，利用根尖有丝分裂中期染色体和花粉母细胞减数分裂中期Ⅰ染色体的N-分带，快速、准确地鉴定了硬粒小麦一簇毛麦双二倍体、普通小麦一簇毛麦异耐加系V〓、V〓、V〓、V〓和V〓，普通小麦一簇毛麦异代换系V〓以及一些具有易位的杂种后代。

It also occures in cold weather because the permeability of the endodermal cells decreases rapidly below 5℃, so the root resists the entry of water.

在寒冷的季节也同样会发生生理干旱。因为在5℃以下时内皮层细胞的渗透性迅速降低，因此根会抵抗水的进入。

Report gene and in situ hybridization indicate the expression of OsPTF1 in leaf, lateral root and root phloem except for epidermic cells in root.

通过报道基因和RNA原位杂交分析表明，OsPTF1在叶片各组织中均表达，在侧根和根的韧皮部区域表达，但在表皮细胞中不表达。

With a model of chronically compressed dorsal root ganglion, the present study was undertaken to test how the plasticity of sympathetic sensory coupling is and whether the coupling is mediated by intracellular messenger PKA by analysing extracellularly recorded spontaneous activity of single A fibers originating from the CCD neurons in vitro.

本实验在背根节慢性压迫模型上，采用离体灌流DRG和单纤维记录神经元自发放电的方法研究了初级感觉神经元的交感感觉耦联作用及其细胞内机制。

The cytogenetic toxic effects of different concentration of As2O3 within different time on the cell of Vicia Faba root tip were studied.

本文以蚕豆根尖为材料，研究不同浓度As2O3在不同的处理时间内对蚕豆胚根根尖的细胞遗传学毒性效应。

The aim was to research the genotoxicity of shampoo concentrations of 3 brands to root tip of Vicia faba cell, and provide the reference for genotoxicity of shampoo to human body.

［目的］研究了3个品牌洗发水浓度对蚕豆根尖细胞的遗传毒性效应，为洗发水对人体产生遗传毒性问题的认识提供参考。

Magnesium sulfate has significant genotoxicity to Vicia faba root tip cells.

硫酸镁对蚕豆根尖细胞具有明显的遗传毒性效应。

As the increase of the concentration of magnesium sulfate and time, the micronucleus and the chromosomal aberration of Vicia faba root tip cells increased first and then decreased.

且随着硫酸镁溶液浓度的升高和处理时间的延长，蚕豆根尖细胞的微核率和染色体畸变率均呈先上升后下降的趋势。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
