The karyotypes and the Giemsa-C banding patterns of Aegilops tauschii (85A-34) and Hordium vulgare (H2) and regenerated plants from embryo callus of hybrids between Ae.tauschii and H.vulgare (2n=28) were confirmed by karyotype analyzing and Giemsa-C banding technique in this study, thus proved that the regenerated plants from embryo callus of hybrids between Ae.tauschii and H.vulgare (2n=28) were spontaneously chromosal doubling amphidiploid.

本研究通过染色体组型分析和Giemsa--C带显带技术，确定了节节麦（85A85A-34）、栽培大麦（H2）、节节麦×大麦杂种胚再生植株(2n=28)的染色体组型和Giemsa--C带核型，证明了节节麦×大麦杂种胚再生植株(2n=28)为自发加倍的节节麦－大麦双二倍体。

We suggest that this gene from amphiploid Am3 most likely belongs to a novel resistance gene, and temporary designated LrPS.

因此，双二倍体小麦Am3携带的隐性抗叶锈病基因可能是一个新的抗病基因，暂定名为LrPS。

The chromosome composition of Yuan Zhong 2, a common wheat-Ag.intermedium partial amphiploid (2n=54), was analyzed with the genomic in situ hybridization,in which the biotinylated total DNA of Ag.intermedium as the probe and the total DNA of common wheat cv.Chinese Spring as blocking DNA were used to hybridize with the chromosome DNA of Yuan Zhong 2 at mitotic metaphase in root tip cells.

为分析普通小麦-天兰冰草部分双二倍体-远中2号(2n=54)的染色体构成，用生物素(biotin-16-dUTP)标记天兰冰草染色体组DNA作为探针，以普通小麦品种中国春染色体组DNA为封闭DNA，与远中2号的有丝分裂中期染色体DNA进行了分子原位杂交。

Wheat germplasm lines were obtained from the posterity of Aegilops tauschii-Triticum Carthlicum amphiploid, and analysis results showed that the 30 germplasm lines have many excellent characters, such as multi-tillers, multi-spikes per plant, good disease resistance, large ear, etc., they are very useful in genetic improvemert of wheat.

从粗山羊草与硬粒小麦合成的双二倍体后代中选育出30个种质系，对其鉴定结果表明，它们的分蘖力、单株穗数、抗病性、穗长等性状表现优异，具有重要利用价值。

The stuccoed cluster, now weighing perhaps twice what the bare wax weighed, is put into an autoclave and heated to 180 degrees F.

该stuccoed集群，现在体重的两倍，也许是什么裸蜡权衡，是投入一釜和加热到180度双床300防扩散安全倡议。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。

In groundings, single hull tankers were observed to have a spill 8 times more often than double hull tankers.

在搁浅，单壳油轮发现有泄漏的8倍多于双壳油轮。

Four further single mutants ofN546(N546G,N546D,N546K,N546Δ), three double mutants and a triple mutant were constructed,and toxins were purified by isoelectric precipitation and an AKTA purifier 100 system.When bioassayed against H.armigera using purified toxins,N546ALC_(501.67μg/mLshowed 1.78 times increased toxicity than wide-type Cry1AcLC_(50 2.98μg/mL,and mutant N546D,N546K and N546Δshowed a great loss in toxicity.

对N546进一步突变，获得了突变子N546G、N546D、N546K和删除突变N546Δ及3个双突变和1个三突变，利用等电点沉淀法和AKTApurifier 100系统纯化了毒素蛋白，生测发现N546ALC_(50为1.67μg/mL对棉铃虫毒力比野生型Cry1AcLC_(50为2.98μg/mL提高了1.78倍，而N546D、N546K和N546Δ的毒力则降低了80～90%。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
