二倍的

GISH technique was applied to TAF46 a partial amphiploid (2n=8x=56) derived from a Thinopyrum intermedium×Triticum aestivum hybrid and to 6 of the possible disomic addition line derived from it to determine the genome origin of the alien genome and the addition lines.

应用GISH对小偃麦部分双二倍体TAF46(2n=8x=56)及其衍生的6个二体异附加系的中间偃麦草染色体组种类进行了分析、鉴定。

Compared with diploidy , the seedlings of Pasthyrostachys juncea with tetraploidy have stronger viability , higher nutrient contents and better tolerance of lower temperature , drought and other extremely environments .

与二倍体新麦草相比，染色体加倍后的四倍体新麦草的种苗生活力强，种子营养成分含量高，对低温，干旱等极端环境的适应能力强。

Soybean evolution from the ancient tetraploid flowers pollinate crops since the diplont, low level of genetic variation within species, genome larger and contains extensive areas of reproduction and rich repeat sequences, chromosome and small cells to carry out genetic research, which makes soybean genetic map study clearly behind other cr...

大豆是由古四倍体演变而来的二倍体自花授粉作物，种内遗传变异程度低，基因组较大并含有广泛的复制区和丰富的重复序列，染色体又很小，难于进行细胞遗传学研究，这使得大豆遗传作图研究明显落后于其它作物。

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。

Wecompare the results among the polyploid Penna model, diploid Penna model and haploidyPenna model, to fred what are same among them.

将建立的多倍体模型与单倍体、二倍体模型进行定性的比较，发现它们在本质上的相似点。

Dot plot image of DNA fluorescence could form region of diploid and tetraploid in integrated cell.

结果显示：结构完整的细胞DNA的荧光点图形成二倍体、四倍体的区域。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

The overall yield was 43.6%.The yield of reduce of ester was increased nearly one times than the past method because of KBH4-LiCl as the reducing agent instead of NaBH4. Changing the reaction conditions of bromization, the one-way yield enhanced 30%. The yield of reduce of the bromide was added by one times by improving the process. Tefluthrin was achieved by the catalytic esterification of DCC and DMAP.

优化后工艺对四氟对苯二甲酯的还原采用了廉价高效的还原试剂KBH4-LiCl，使收率比NaBH4法提高了近一倍；对溴化反应条件进行了优化，单程收率提高了30%；对溴化物还原条件的优化，使其收率提高了近一倍；采用了催化剂DCC和DMAP合成了最终产品七氟菊酯。

Train it under the condition in 23-25 degrees Centigrade, The monoploid that the rice anther train Callus to "zhonghua11 ", than maturity liploid that embryo lead of it,s callus grow speed to be one times faster and about.

在23~25℃培养条件下，&中花11&水稻花药培养的单倍体愈伤组织，比其成熟胚诱导的二倍体愈伤组织生长速率快一倍左右。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
