Changes in banana genotypes submitted to salinity

Ten diploid banana genotypes were cultivated in nutrient solution with or without NaCl. The experiment was conducted in a greenhouse in an entirely randomized design. The objective of the work was to verify the effect of the NaCl on biometric ecophysiological and nutritional variables.the experiment was collected 21 days after the beginning of the treatments.salinity provoked in the majority of the genotypes significant reductions in almost all of the analyzed biometric variables. It also caused a reduction in transpiration and a tendency to increase diffusive resistance and leaf temperature in all the genotypes.Salinity also caused nutritional alterations in the different plant organs. The Tungia genotype showed higher sensitivity to salt stress and the Lidi genotype showed higher tolerance. The other genotypes showed intermediate degree of tolerance.
