摘　　要：通过农杆菌介导法转入棉花耐盐基因GhNHX1,初步研究结果表明,获得的转基因株系4092具有较好的耐盐性,其在盐含量0.5%~1.5%条件下,发芽率、生物鲜质量以及土壤中出苗率均优于受体R15,说明该基因在提高棉花的耐盐性方面具有一定利用价值。In this study, the cotton lines of transgenic GhNHX 1 gene were analyzed and showed good resistance to salt stress in the salt content of 0.5% -1.5%. The germination rate, biological fresh weight and seedling emergence of transgenic cotton line 4092 were better than the control R15 cotton plant in the different conditions of salt concentration. So the results indicated that GhNHX1 gene would be a good candidate gene to improve salt tolerance of cotton plant in the future.
