Study of the tolerance of ten accessions of carrot (Daucus carota L.) to salinity

The present work has focused on the assessment of the tolerance of ten accessions of carrot (L₁, L₂, L₃, F₄, E₅, R₇, R₈, L₁₀, G₁₁ and S₁₂) to salt stress, grown in the region of Sidi Bouzid. The tests were carried out under plastic greenhouse (during 5 months). The results obtained show that the salt stress reduced the parameters of growth and production. However, a difference in the response to salt stress was recorded between the accessions studied. A reduction in yield of up to 70 % with the concentration 3 g / l of NaCl, for different accessions studied is recorded. However, the accession L₁ who has given the longer roots and dry matter yield and the largest root shows the most tolerant accessions unlike L₁₀, G₁₁ and S₁₂ which are the most sensitive.
