Cowpea (Vigna unguiculata (L.) Walp.) is one of the most important grain legumes in sub-Saharian regions. It contributes to man food security by providing a protein-rich diet. However, its production is limited by abiotic stresses such as salinity. This study aims to evaluate the salt tolerance of 15 cowpea cultivars, at germination stage. The seed germination process consisted of sowing them i...

The effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), in the seedlings’ roots or shoots of three winter canola (Brassica napus L.) cultivars, Colvert (tolerant), Symbol (semi tolerant) and Agat (susceptible). Seedlings were treated with 0 (control), 50, 100 and 150 mM NaCl for 24 h in hydropoic c...

lattice design with nine replicates. All accessions were of special interest in the breeding program. Included as a susceptible check was the commercial variety 'Valery.' One row of 'Valery' was planted as a border around the experimental area. Rhizomes were examined 12 and 19 months after planting, and average infestation per plot was rated on the same scale of 0 to 4. Results are in Table 1, ...

Worldwide, the landscape homogeneity of extensive monocultures that characterizes conventional agriculture has resulted in the development of specialized and interacting multitrophic pest complexes. While integrated pest management emphasizes the need to consider the ecological context where multiple species coexist, management recommendations are often based on single-species tactics. This app...

In order to study the effect of salt stress on the Rhizobium-common bean symbiosis, we investigated the response of both partners, separately and in symbiosis. The comparison of the behaviour of five cultivars of Phaseolus vulgaris differing in seed colour, growing on nitrates and different concentrations of NaCl, showed genotypic variation with respect to salt tolerance. Coco Blanc was the mos...

Drought is a serious threat for sustainable agriculture. Barley represents a species well adapted to environmental stresses including drought. To elucidate the adaptive mechanism of barley on transcriptional level we evaluated transcriptomic changes of two contrasting barley cultivars upon drought using the microarray technique on the level of leaves and crowns. Using bioinformatic tools, diffe...
