The growth of Ficus carica test-tube seedlings on MS media was sharply inhibited by NaCl with lethal in 300 mmolL^(-1) NaCl and, in leaf, dramatical increase in sodium content and K(superscript +)/Na(superscript +) ratio, in addition to proline and soluble sugar accumulation in 0~200 mmolL^(-1) NaCl.

将多次继代培养的无花果试管苗接种在含NaCl不同浓度的MS培养基上，300mmolL^(-1)NaCl使试管苗致死。在0~200mmolL^(-1)NaCl的培养基上，试管苗生长显著受到抑制，叶片中Na含量增加，K/Na上升。

The selectivity for K over Na of the low affinity K uptake system in the roots of Puccinellia tenuiflora was approximately similar to that in glycophytes. However, the selectivity for K over Na of high affinity K uptake system in the roots of Puccinellia tenuiflora was much stronger, which indicated that HAK and HKT played very significant roles in the process.

小花碱茅根低亲和性K 吸收系统对K 、Na 的选择性吸收能力与甜土植物大致相同；但其高亲和性K 吸收系统的选择性能力很强，表明HAK和HKT在此过程中起重要的作用。

The negative side is the sodium cations erode silica sand (Na〓 can fit into silicon-oxygen hexahydric circle). The retained strength increases significantly.

坏的影响是Na〓离子最容易侵蚀石英砂（Na〓恰巧可填满硅氧六元环），使残留强度遽增。

Kochia sieversiana can absorb Na~+ effectively and prevent excessive Na~+ from transporting tothe cotyledon.

碱地肤之所以适应在高盐环境生长的原因就是由于可以有效地吸收、控制Na~+向地上部分转移。

Then the contents of brain tissue water, malonyl diadehyde and the activities of Na+-K+-adenosine triphosphatase (Na+-K+-ATPase), Ca2+-Mg2+-adenosine triphosphatase (Ca2+-Mg2+-ATPase), CuZn-superoxide dismutase and mitochondrial Mn-superoxide dismutase were measured.

测定脑组织含水量、丙二醛含量、钠钾三磷酸腺苷酶(Na~+-K~+-ATPase)、钙镁三磷酸腺苷酶Ca~(++-Mg~-ATPase、铜锌超氧化物歧化酶以及线粒体锰超氧化物歧化酶的活力。

To understand whether there is gene reassortment recently, we also analyzed the evolutionary relationship of these isolates. It appears that no HA/NA reassortment was found.

想了解这段时间内是否出现基因重组，我们也分析了这些分离株NA及HA基因的演化关系，结果显示这段时间内的A型流感病毒在HA及NA基因之间没有出现互换的现象。

Nutrient composition of Vallisneria natans was analyzed. Results show that V. natans contained 218.4 gkg^(-1) of protein, 51.4 gkg^(-1) of crude fat, 37.6 gkg^(-1) of polysaccharides, 265.7 gkg^(-1) of ash; and 147.6 gkg^(-1) of total amino acids, 55.0 gkg^(-1) of essential amino acid; and a number of mineral elements, such as 60.5 gkg^(-1) of K, 10.9 gkg^(-1) of Ca, 16.3 gkg^(-1) of Fe, 12.7 gkg^(-1) of Na.

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。
