Abstract

Research and study of adaptation parameters to water deficit is a key work in any attempt to improve the safety and productivity of wheat governed by water deficits areas. The proposed work attempted to explain the adaptive functioning of ten genotypes of durum wheat (Triticum durum Desf.) under different water regimes. It attempted to elucidate the relationships and skills offered by the variability of the species cultivated in the process, the morphological remodeling of root and stem parts in drought tolerance and their relationship with productivity. The effect of water deficit on the strength of the meristem part was very variable depending on its intensity, the nature of the genotype and the parameter considered. The process of transmission and viability of tillers were more sensitive to water deficit statement in the different intensities. The results showed that all levels of water deficit adopted (55%, 52%) (ADH1, ADH2) in this study lead to a reduction in the length among all genotypes tested. The results obtained in this study showed that the number of tillers formed and preserved closely depended on the morphological characteristics of the adventitious roots
