The following results have been obtained: 1 Expression of SbNHX1 in E. coli enhanced Na+ and K+ tolerances, but not to others; 2 The sequence from 1353-1514bp in SbNHX1 gene played a role for SbNHX1 to Na+ and K+ tolerances; 3 The Na+/H+ antiporter of Salicornia Bigelovii Torr. catalysed Na+/H+ or K+/H+ exchange with equal affinity, which indicates that the SbNHX1 is more likely to locate on member of vacuolar, and responds to transport Na+ into the vacuole from cytoplasm.

证明了SbNHX1能抵抗Na+和K+的胁迫，但对其它盐离子没有抗性；2）证明了北美海蓬子Na+/H+逆向转运蛋白基因（SbNHX1）C末端从基因的C末端1353bp至1514bp的序列在耐盐中起一定的作用；3）证明了北美海蓬子Na+/H+逆向转运蛋白（SbNHX1）对Na+和K+交换的等亲和性，对于这一点，说明北美海蓬子Na+/H+逆向转运蛋白与定位于液泡膜上的Na+/H+逆向转运蛋白的功能相似。

The successive encounters with Colette and Monsieur Lucien have revived Antoine's nostalgia and when he realizes that he has misplaced a photo of Sabine that was, for him, of capital sentimental importance, he decides to take the first seps to clear up the misunderstanding that has settled between the young lady and him.

The results of studying the effects of several plant growth regulating substances on pollen germination and tube growth in pear (Pyrus serotina Rhed.) by cultivating pollens in liquid media showed that GA3,TRIA,IAA and 2,4D stimulated pollen germination and tube growth when pollen was cultivated in their lower concentration media.

采用花粉液体培养法研究了植物生长调节物质对梨花粉萌发和花粉管生长的影响，结果表明：较低浓度的赤霉素、三十烷醇、吲哚乙酸及2，4-D均能促进花粉萌发和花粉管生长，而超过一定浓度时却起抑制作用，最适宜于花粉萌发和花粉管生长的赤霉素浓度为50～300mg/L，三十烷醇为3～100mg/L，吲哚乙酸为5～25mg/L，2，4-D为5～10mg/L。
