Summary: The objective of study was to determine sensitivity of varieties and hybrids of trifoliate to salinity during the rootstock stage. The experiment was carried out in a green house of UAEAg/CTRN of UFCG in a randomized block design, with five repetitions each consisting of four plants, five levels of irrigation water salinity (control, tap water with electrical conductivity (ECw) of 0.41 dS m-1 and water with ECw of 1.0; 2.0; 3.0 and 4.0 dS m-1) and six genotypes. During 150 days growth and physiological variables were evaluated. Significant effects of genotypes and salinity in the variables were observed. In case of growth variables, more expressive reduction was found for total dry matter with unit increase of ECw. In lemon Volkameriano with increase in salinity, increase in total dry weight was observed where as a linear reduction was found in citrange Troyer and HTR 069. The lemon Volkameriano is indicated for the formation of rootstock seedlings of citrus under saline conditions due to its lower sensitivity.
