Study of the tolerance of ten accessions of carrot (Daucus carota L.) to salinity
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2014, Vol 10, Issue 3
Abstract
The present work has focused on the assessment of the tolerance of ten accessions of carrot (L[sub]1[/sub], L[sub]2[/sub], L[sub]3[/sub], F[sub]4[/sub], E[sub]5[/sub], R[sub]7[/sub], R[sub]8[/sub], L[sub]10[/sub], G[sub]11[/sub] and S[sub]12[/sub]) 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 L[sub]1[/sub] who has given the longer roots and dry matter yield and the largest root shows the most tolerant accessions unlike L[sub]10[/sub], G[sub]11[/sub] and S[sub]12[/sub] which are the most sensitive.
