| Résumé : |
The objective of this work is to study the effect of water stress, and variability of response in seven genotypes of durum wheat (Triticum durum Desf): Djenah khetaifa, Bidi 17, Guem goum Rkham, Rahouia, Beliouni, Vitron and Waha.
In the first part, we studied various morphological parameters, biochemical and physiological under five irrigation levels (100, 80, 50, 25 and 12.5% of field capacity); the choice of levels of irrigation is to apply at third leaf. The results show that water stress caused a reduction in leaf area, decreased water content, rate of water loss and the rate of total chlorophyll. Similarly, increased specific leaf weight, stomatal resistance and accumulation of prolin and soluble sugars are stored.
In the second part, were analyzed by SDS-PAGE total protein expressed in leaf and root the same genotypes after water stress applied in vitro by addition of PEG 600 to 7%. The electrophoresis diagrams, we give these subunits both in controls than in stress,while others are present or absent in stressed and witnesses.
In conclusion, the study showed that water stress causes the same response mechanisms among seven genotypes but to different degrees. |
