二倍的

Studies showed that the Giemsa-C banding patterns of Ae.tauschii- H.vulgare amphidiploid is much in accord with that of its two parents, and this further proved that the regenerated plants from embryo callus of hybrids between Ae.tauschii and H.vulgare (2n=28) were spontaneously chromosal doubling amphidiploid.

分析表明，节节麦-大麦双二倍体Giemsa--C带核型与两个亲本的带型基本一致，这证明了节节麦-大麦双二倍体的染色体组成。

Apomixes is comparable to the conditions of apogamy and apospory, which are seen in many ferns.

在这个过程中珠心的二倍体细胞发育为胚胎，二倍体种子的遗传组成与亲本完全相同。

The chromosome number of the mutated tomato (2n=4x=48) was twice that of the control.

变异材料的细胞染色体(2n=4x=48)为二倍体材料的二倍。

Compared diploid fodder beet with tetraploid fodder beet, tetraploid plants put up characteristics of bigger and thicker dark green leaf, more folds on leaf, stronger footstalk and so on .we can take those characters as the advancing index in testing tetraploid fodder beet.

饲用甜菜四倍体植株与二倍体植株相比，表现出叶片增大变厚，叶色浓绿，叶面多皱褶，叶柄粗壮等特点，可以将这些特点作为饲用甜菜四倍体田间初步筛选的指标。

The results support the hypothesis of Polyploid gigantism and show the effect of polyploidy on nuclear size.

研究结果如下：一、三倍体牡蛎鳃上皮细胞核长轴、外套膜与唇瓣结缔组织中血淋巴核径的大小明显大于二倍体（P＜0.001），二倍体牡蛎直肠上皮细胞的高度与三倍体差异不明显（0.05＜P＜O.1）。

The number of chloroplast in stomata guard cell, density, length and width of stomata were observed.

以苹果和梨的二倍体和多倍体为试材，比较了气孔保卫细胞叶绿体数目、气孔密度、气孔长和气孔宽四个性状与倍性的关系，分析各个性状用于倍性鉴定的可靠性，并采用两类性状同时进行判别分析，建立判别分析方程。

If 〓mRNA positive expression, its DNA heteroploid type display as triploid or hypodiploidy, if 〓mRNA negative expression, its DNA heteroploid type display as hyperdiploidy、tetraploid or Bistem line. These from one flank demonstrate the role of 〓 gene suppress the proliferation of malignant tumor

表达阳性者，其DNA异倍体主要表现为三倍体或低二倍体，〓表达阴性者，其DNA异倍体主要表现为高倍体、四倍体和双干系，从一个侧面显示出〓基因的抑制恶性肿瘤细胞增殖的作用。

However, analysis of DNA methylation level indicated that the total DNA methylation levels were not significantly different between diploid and autotetraploid. Autotriploid showed a trend of low DNA methylation level. It implied that the alterations of DNA methylation levels were not linear with the autopolyploidy level in watermelon.

有趣地是，二倍体与四倍体西瓜相比DNA甲基化水准却未发生大规模的调整，而三倍体西瓜显示出较为明显的低DNA甲基化水准趋势，表明西瓜同源多倍化过程中其基因组DNA甲基化水准变化与其倍性不成线性关系。

The improved L.D.Cua method was used to induce tetraploid of Trichosanthes kirilowii Maxim. The suitable treating time of 0.2% colchicine, the morphology characters and cytology identification between plants of diploid and obtained tetraploid were studied.

采用改良L.D.Cua法诱导短把栝楼获得四倍体，研究了0.2%浓度的秋水仙碱诱导短把栝楼染色体倍性变异的最佳处理时间、四倍体栝楼与原栝楼的形态特征及其四倍体与二倍体的细胞学鉴定。

Pitardii,all from the Jinshajiang Valley of Yunnan and Sichuan, were cytologically studied in this work. Among 34 populations of C.reticulata studied here, 21 were found to be tetraploids (2n=60), 11 hexaploids (2n = 90), and the remaining two diploids (2n = 30). Tetraploid was reported in C. reticulata for the first time and its karyomophology was studied.

reticulata及其两个近缘种(怒江山茶C.saluenensis和西南山茶C.pitardii)进行了细胞学研究。34个居群的云南山茶花中，21个居群是四倍体类型(2n=60)，11个居群是六倍体类型(2n=90)，另2个居群为二倍体(2n=30)，云南山茶花的四倍体类型为首次发现，并且进行了核形态研究。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
