Abstract

This study was conducted with the aim ofdetermining tomato plant behavior during the vegetative periodunder different saline treatments; thus, growth and waterrelations were evaluated in cv. Amalia, subjected to severalNaCl treatments in the medium for 264 h. It was performed in agrowth chamber with a 13-h photoperiod, a photosyntheticallyactive radiation of 380 ?mol.m-2.s-1, a day/night temperature of25/180C and a day/night relative humidity of 60/70 %. Plantsdeveloped in pots containing silica sand and put in trays,besides adding Hoagland nutrient solution. The treatmentsused were 0, 50, 100 and 200 mM NaCl. Once treatmentapplication phase was concluded, plants were placed undernutrient solution conditions without NaCl for 264 h to evaluatetheir recovery. Evaluations of biomass, stomatal conductance,transpiration and leaf water, osmotic, pressure and osmotic ata top saturation potentials before dawn and root waterconductivity were recorded after 24, 48, 120 and 264 h ofapplying treatments, as well as after staying for 264 h underrecovery conditions. The analysis of data showed a significantreduction of different variables evaluated, when increasingNaCl content in the medium, besides observing that after 24 hof applying treatments, the osmotic adjustment had not yetoccurred.
