A pot experiment with twenty-three open-pollinated Liriodendron chinense families from Liping of Guizhou at two nitrogen levels was conducted to investigate family variation and inheritance of nitrogen absorption and utilization efficiency related to nitrogen supply.

选用来自贵州黎平马褂木优良种源的23个优树自由授粉家系，设置低N和高N2种N素水平的盆栽试验，以研究马褂木N素吸收和利用效率的家系遗传变异及N素水平的影响。

A multivalent nonmetallic element of the nitrogen family that occurs commonly in inorganic phosphate rocks and as organic phosphates in all living cells; is highly reactive and occurs in several allotropic forms.

一种多价的氮族非金属元素，通常见于无机磷酸盐岩石中或作为有机磷酸盐存在于活细胞中，极其活跃，有多种同素异形体。

By using the specific PCR primers and T-A cloning, two species of AOB, 1 species of NOB and 11 species of ANAMMOX were detected in the SBBR one-step completely nitrogen removal process. One of the AOBs dominated at this reactor belonged to the family of Nitrosomonas for the similarity of 98% while another one was almost the same with an uncultured one.

同时通过T-A克隆的方法，在系统中发现2类不同的AOB序列，一类与氨氧化菌标准菌株Nitrosomonas有98%的较高相似性，另一类则与其它一种未得到纯培养的AOB接近，相似性为99%。

"Thymine: Organic compound of the pyrimidine family, often called a Base, consisting of a ring containing Both nitrogen and carbon atoms, and a methyl group."

胸腺嘧啶：一种嘧啶类有机化合物，通常叫做基底，由含有氮和碳原子以及甲基的环形物组成。

Of the nitrogen family that occurs commonly in inorganic phosphate rocks and as ''.

有机'。''磷酸盐存在于活细胞中，极其活跃，有多种同素异形体。

Solid poisonous element in the nitrogen family,usually gray or yellow,brittle and crystalline.

氮族化和物中的著名毒物，通常呈灰色或黄色，易碎结晶体。

The result showed there existed significant differences among families in seedling growth, dry matter accumulation, leaf shape as well as root parameters at high and low nitrogen levels. Remarkable reduction in seedling height, dry matter accumulation, leaf and root parameters were observed under low nitrogen stress, whereas larger proportion of photosynthesis production was allocated into roots to promote nitrogen absorption. Family variation in seeding growth, leaf and root parameters were increased under low nitrogen stress in comparison with high nitrogen level, which would be benefit to discriminate superior L. chinense families with high nitrogen efficiency. Nitrogen efficiency of different L.

结果表明：不同氮素水平下，马褂木苗的生长、干物质积累、叶片和根系等性状皆存在显著的家系遗传差异；低氮胁迫将显著抑制马褂木苗叶片发育和根系生长，影响苗高生长和干物质积累，但低氮素水平下生产的光合产物则较多地分配至地下根系部分以促进对氮素的吸收利用；与高氮处理比较，低氮胁迫加大了苗木生长、叶片和根系参数等家系遗传分化，有利于鉴别高氮效率的马褂木优良家系。

The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

结果表明，两种氮肥处理之间以及不同家系之间各营养成分含量差异均达极显著水平；增施氮肥有利于提高秸秆的粗蛋白和粗脂肪的含量，降低酸性洗涤纤维和中性洗涤纤维的含量；两种氮水平条件下，不同家系之间秸秆各主要营养成分含量的变异性分离均符合正态分布，并存在不同程度的双向超亲分离；不同基因型的玉米对氮素的敏感性各异。
