Merril) and different strategies have been adopted to overcome this problem. Commercial exploitation of tolerant genotypes to salinity is a good alternative to obtain economical yields in these areas. For this reason, it is important to have rapid methods to assess the tolerance to this stress especially in the early stages of growth. The aim of this study was to evaluate the salt tolerance in nine soybean genotypes. Experiments were carried out in a greenhouse under controlled conditions. The rate of salinity tolerance of germination (IG ), shoot length (ILB ), root length (ILR ), shoot dry matter (IMSB ) and root (IMSR ), as well as injury of cell membrane were measured in all genotypes treated with NaCl (chloride sodium) at concentrations 0 to 150 mM. The results obtained based on physiological criteria allowed the identification of AT22 and INCASoy36 as the most tolerant cultivars compared to other genotypes, thus those genotypes seem to be promising to achieve higher productivity in areas affected by salt 2015 artículo científico 1819-4087 https://www.redalyc.org/articulo.oa?id=193243175016 es http://www.redalyc.org/revista.oa?id=1932 Cultivos Tropicales application/pdf Instituto Nacional de Ciencias Agrícolas Cultivos Tropicales (Cuba) Num.4 Vol.36 |
