Effects of water stress on two genotypes of Durum wheat (Triticum durum Desf.) and Common wheat (Triticum aestivum.L) inoculated with Frankia CCI3 Azospirillum brasilense and Mycorrhiza

This study aims to evaluate the response of common and durum wheat to inoculation by micro-symbionts. Two common and two durum wheat genotypes were inoculated by three inoculums Frankia CCI3 (IF), Azospirillum brasilense (IA) and Mycorrhiza (IM) in presence or in absence of water stress in a greenhouse assai. After the heading stage plants were collected. The parameters of growths and the dry weight of plants and roots were measured as well as SPAD index and nitrogen dosage. The obtained results are significant. They showed that the inoculation with the IM treatment enhanced leaves, ear and roots length. IA treatment has a favorable effect on the nitrogen accumulated in leaves of inoculated plants under control and water stress condition.
