    Abstract The present investigation was undertaken to study the inheritance pattern of morpho-physiological traits: relative water content, excised leaf water loss, flag leaf area and membrane stability, in an F3 population of durum wheat (Triticum durum Desf.). The results reflected a satisfactory range of variability in the evaluated traits. Range magnitude of the four traits represented the equivalent of 5.0 to 11.4 times the least significant difference at 5% level. Transgressors with variable frequency were observed for all the measured traits. In fact 25% of the F3 lines showed a relative water content greater than 85%, 3% has a flag leaf area superior to 26 cm², 8% had a low leaf water loss rate and 11% expressed a low electrolyte leakage rate, suggesting a high membrane stability. Medium to high broad sense heritability estimates were noted for the measured traits. Medium to high genetic gain expressed as percent of the base population mean was observed, taking the following values: 11.0%, 24.0%, 68% and 88%, for relative water European Scientific Journal April 2015 edition vol.11, No.12 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 content, flag leaf area, excised leaf water loss rate, and percent of cell injury, respectively. Altogether, the obtained results indicated that the studied cross population would be of interest in the breeding program and an effective progress can be made through selection of these morpho-physiological characters to enhance stress tolerance and grain yield potential

    Relation Entre L’activité Biologique Et Le Comportement Hydro Physique Des Sols Dans Le Contexte Du Systéme Prairial Naturel Irrigué A L’eau Usée

    The practice of irrigation using wastewaters is a promising solution to alleviate the problem of water stress in semi-arid regions. Our study focuses on the impact of the practice of irrigation with wastewaters on both physical and biological components of soil; as well as the interactive effects of these two components on water functioning in soil of eastern Algeria. The water analysis showed high organic and fine-particle pollutions, but with no significant influence on soil properties. Our findings revealed positive effects of wastewater irrigation that increased the abundance of earthworm communities, soil porosity, water retention and hydraulic conductivity.
