Biologie Résumé :
The present work aims to determine the protein relationship and the physio-biochemical and histo-morphological functions of two tomato varieties (Lycopersicum esculentum Mill var: RioGrand, Heinz) in saline conditions. For this purpose, four factorial experiments were carried out. In a Hoagland solution in a fully randomized block device with four concentrations of NaCl (S0: 0, S1: 25, S2: 50, S3: 150) mMol and four repeats, the work was performed on 32 experimental units for each experiment under controlled conditions. During the germination phase morphological observation showed that the high saline concentration (150 mMol) has a depressive effect on the germination capacity for both varieties. Growth monitoring and seedling development in saline conditions led to the conclusion that salinity significantly decreased the physio-biochemical and morphological parameters (Sf, Psf, Nf,Pft, Bsr, Bsa, Sr, Tre, ChlT, K + r, K + f, Prot) compared to the control against a remarkable accumulation of osmolgulators (Pro, Suc) this consistent with the accretion of the Na+ ion which reflects on the coefficient of selectivity Na + / K + in the leaves and roots of the main component explained (ACP) by the total proteins revealed of very high significant correlations (positive, negative) with the studied parameters this last one seems to have clarified the state of these two varieties (RioGrand, Heinz) in the saline conditions it emerges that these two genotypes showed different behaviors under the high saline concentrations (150 mMol) or we note at the histological study level a structural absence of the growth pri mayor and secondary and an increase in the size of parenchymal cell lignification in the susceptible variety (RioGrand) where the sensitivity index (Is) was confirmed Its sensitivity and an absence of secondary growth in the tolerant variety (Heinz) at the root level this difference lies in the intensity of the bands as well as in the number of bands obtained each band of an

Biologie Résumé : The main objective of the present study is the evaluation of several genotypes of beans Phaseolus vulgaris L. cultivated in Algeria for phenological, physiological and phytochemical traits under salt stress conditions. According to their responses to salinity and their phenotypes, four parents were selected. To carry out this study a half-diallel cross between the parents was undertaken producing six F1 hybrids; the six F1 hybrids were planted to allow self-fertilization and the production of the F2 offspring. All F1 and F2 populations and their parents were planted in a complete randomized block design, under three salt treatments 0, 50 and 100mM for the evaluation of phenological, physiological and phytochemical characteristics, the results obtained were subjected to diallel analysis and then genetically analyzed using SSRs and SNPs as well as a single marker analysis to highlight the correlation between phenotypic and genotypic data. The diallel analysis revealed high significant genotypic variations between the four parents and their six F1 hybrids. General and specific combining abilities were highly significant for all traits studied under all conditions, revealing the important role of both additive and dominant genetic effects for heredity of the traits under study. Parental genotypes Améilore Roza and Coco nain proved to be the best combiners for salinity tolerance; on the other hand the hybrids Amina x Améliore Roza; MGT x Améliore Roza and Coco nain x Amina recorded a high significant percentage of heterosis. Molecular analysis showed that populations from the half diallel cross have a high genetic diversity, these populations can be used later for the production of RILs; in addition, single marker analysis revealed that several SSRs markers were associated with the different traits studied, the markers BMd37 (LG6) BM200 and ATA243 (LG1) showed a strong association with the production of polyphenols and total flavonoids, these markers can be linked to important genes implying a salinity tolerance. These results indicate a high genetic variability in bean populations and a possibility of genetic improvement under salt stress, especially for the biosynthesis of secondary metabolites.
