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。

采用流式细胞术检测新鲜组织细胞的DNA倍体性和临床分期一样可以预测鼻咽癌患者的预后；DNA异倍体患者比二倍体患者更容易出现远处转移而导致治疗失败。

Results The p53 gene mutation rate of colorectal cancer was 50%. The rate of apoptosis of tumor cells having mutation of p53 gene (22.11%) was much lower than that having no p53 mutation (40.57%, P＜0.05). Heteroploid cells had been found in 10/13 tumor samples with p53 gene mutation and 6/13 samples without p53 mutation (P＜0.05). The rate of apoptosis had no difference between the heteroploid cases and diploid cases.

结果 大肠癌标本p53基因突变率为50%；其中突变组肿瘤细胞凋亡率(22.11%)明显低于未突变组细胞凋亡率(40.57%)，(P＜0.05)；突变组异倍体细胞百分率(占76.9%)明显高于未突变组(占46.2%)，(P＜0.05)；异倍体肿瘤细胞凋亡率为34.0%，二倍体肿瘤细胞凋亡率为40.7%，二者差异无显著性(P＞0.05)。

These microscopic characteristics of pollen grain and stomata could be used as the evidence to identify diaploid spieces and hexaploid, octoploid spieces whose chromosome ploidies are hugely different.

结论］用花粉粒和气孔的一些微观特征作为鉴别二倍体和六倍体、八倍体等染色体组倍数相差较大的物种有一定的依据。

A high performance liquid chromatographic method was established for determination of caffeic acid contents in tetraploidy taraxacum officinale and diplontic taraxacum dissectum.

本文采用四倍体药蒲公英和二倍体多裂蒲公英为材料，通过HPLC法测定并比较两种蒲公英中咖啡酸的含量，以大力推广产量高，抗逆性强，药用活性成分高的优质多倍体蒲公英新品种。

Pooling together thedata from comparing the 4x original varieties with their corresponding 2x varietiessince 1979,it was found,that tetraploidy could cause variation of manyagronomic traits.

自1979年对四倍体水稻原种(4x)和相应的二倍体水稻品种(2x)进行了对比，结果发现，四倍体水稻原种的许多农艺性状发生了变化。

Progeny of this plant included aneuploids, such as trisomic and tetrasomic.

这一异常植株的花粉母细胞仍为混倍体，其子代中有二倍体和各种非整倍体植株。

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

The position of the word on the board can also score points, as some of the squares which take the letters are given a double or triple letter score (the vowel E, worth one point, would score three on a triple letter score square).

单词在棋盘上的位置也与得分有关，因为有些方格是二倍格，有些是三倍格(如：只值1分的元音E放在一个三倍格中就可得三分)。
