The present study was undertaken on two varieties of broad bean Vicia faba (Sidi Aïch and Super Aguadulce). The device was mounted on a substrate prepared by mixing sand, soil and compost, the substrate was artificially contaminated with three doses of lead nitrate [Pb(NO3)2] 0, 500 and 1000 ppm. Our objective is to follow the behavior of plant opposite the stress by evaluating the physiological parameters. The results reveal a reduction in the parameters of the productivity (chlorophyll and proteins production) with an increase in the osmoregulators (soluble sugars and proline).These results show that the production of broad bean is strongly modified by the disturbance of its internal physiology under lead exposure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broad%20bean" title="broad bean">broad bean</a>, <a href="https://publications.waset.org/abstracts/search?q=lead" title=" lead"> lead</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20parameters" title=" physiological parameters"> physiological parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=phytotoxicity" title=" phytotoxicity"> phytotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/33247/phytotoxicity-of-lead-on-the-physiological-parameters-of-two-varieties-of-broad-bean-vicia-faba" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33247.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> The Effect of Salinity and Bentonite on the Hydrous Behaviors and Sodium Content of the Broad Bean Vicia faba var.

It limits growth and productivity of plants and degrades agricultural soils and ecosystem in arid and semi arid area. The study was conducted on Vicia faba L.’Semilla violeta’. Sowing was realized in plastic pots containing sandy substrates of bentonite 0, 3, 5, 7, and 10% associated with abiotic stresses of salinity corresponding to doses of NaCl, MgCl2 and MgSO4 20, 40, and 60 mmol/l respectively. The purpose of this work is to study the combined effect of salinity and of bentonite on a plant commonly cultivated in Algeria the broad bean Vicia faba has through the chemical and hydrous parameter. The results show that the combined action of strong concentration salt (40 and 60 mmol/l) and of bentonite a reduction of the relative content water reveals, against an increase in the content of hydrous deficit and of sodium. The growth of broad bean is significant in the substrate amended to 5 % of bentonite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salinity" title="salinity">salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=bentonite" title=" bentonite"> bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicia%20faba%20L" title=" Vicia faba L"> Vicia faba L</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20content" title=" sodium content"> sodium content</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrous%20parameters" title=" hydrous parameters"> hydrous parameters</a> </p> <a href="https://publications.waset.org/abstracts/31285/the-effect-of-salinity-and-bentonite-on-the-hydrous-behaviors-and-sodium-content-of-the-broad-bean-vicia-faba-var-semilla-violeta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Sporting Events among the Disabled between Excellence and Ideal in Motor Performance: Analytical Descriptive Study in Some Paralympic Sports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guebli%20Abdelkader">Guebli Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Reguieg%20Madani"> Reguieg Madani</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkadi%20Adel"> Belkadi Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sbaa%20Bouabdellah"> Sbaa Bouabdellah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The identification of mechanical variables in the motor performance trajectory has a prominent role in improving skill performance, error-exceeding, it contributes seriously to solving some problems of learning and training. The study aims to highlight the indicators of motor performance for Paralympic athletes during the practicing sports between modelling and between excellence in motor performance, this by taking into account the distinction of athlete practicing with special behavioral skills for the Paralympic athletes. In the study, we relied on the analysis of some previous research of biomechanical performance indicators during some of the events sports (shooting activities in the Paralympic athletics, shooting skill in the wheelchair basketball). The results of the study highlight the distinction of disabled practitioners of sporting events identified in motor performance during practice, by overcoming some physics indicators in human movement, as a lower center of body weight, increase in offset distance, such resistance which requires them to redouble their efforts. However, the results of the study highlighted the strength of the correlation between biomechanical variables of motor performance and the digital level achievement similar to the other practitioners normal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sports" title="sports">sports</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20disabled" title=" the disabled"> the disabled</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20performance" title=" motor performance"> motor performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Paralympic" title=" Paralympic"> Paralympic</a> </p> <a href="https://publications.waset.org/abstracts/92665/sporting-events-among-the-disabled-between-excellence-and-ideal-in-motor-performance-analytical-descriptive-study-in-some-paralympic-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92665.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> The Biofertilizer Effect of Pseudomonas of Salt Soils of the North-West Algerian, Study of Comportment of Bean (Vicia Faba)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djoudi%20Abdelhak">Djoudi Abdelhak</a>, <a href="https://publications.waset.org/abstracts/search?q=Djibaoui%20Rachid"> Djibaoui Rachid</a>, <a href="https://publications.waset.org/abstracts/search?q=Reguieg%20Yassaad%20Houcine"> Reguieg Yassaad Houcine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our study focuses on the identification of some species of Pseudomonas (P4, P5, P7 and P8) isolated from saline soils in northwestern Algeria and the effect of their metabolites on the growth of Alternaria alternata the causative agent of the blight of the bean disease (Vicia faba). We are also interested in stimulating the growth of this plant species in saline conditions (60 mM/l NaCl) and the absence of salts. The analysis focuses on rates of inhibition of mycelial growth of Alternaria alternata strain and the rate of growth of plants inoculated with strains of Pseudomonas expressed by biometrics. According to the results of the in-vitro test, P5 and P8 species and their metabolites showed a significant effect on mycelia growth and production of spores of Alternaria alternata. The in-vivo test shows that the species P8 and P5 were significantly and positively influencing the growth in biometric parameters of the bean in saline and salt-free condition. Inoculation with strain P5 has promoted the growth of the bean in stem height, stem fresh weight and dry weight of stems of 108.59%, 115.28%, 104.33%, respectively, in the presence of salt Inoculation with strain P5 has fostered the growth of the bean stem fresh weight of 112.47% in the presence of salt The effect of Pseudomonas species on the development of Vicia faba and the growth of Alternaria alternata is considering new techniques and methods of biological production and crop protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pseudomonas" title="pseudomonas">pseudomonas</a>, <a href="https://publications.waset.org/abstracts/search?q=vicia%20faba" title=" vicia faba"> vicia faba</a>, <a href="https://publications.waset.org/abstracts/search?q=alternaria%20alternata" title=" alternaria alternata"> alternaria alternata</a>, <a href="https://publications.waset.org/abstracts/search?q=promoting%20of%20plant%20growth" title=" promoting of plant growth"> promoting of plant growth</a> </p> <a href="https://publications.waset.org/abstracts/30608/the-biofertilizer-effect-of-pseudomonas-of-salt-soils-of-the-north-west-algerian-study-of-comportment-of-bean-vicia-faba" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30608.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Study of Pseudomonas as Biofertiliser in Salt-Affected Soils of the Northwestern Algeria: Solubilisation of Calcium Phosphate and Growth Promoting of Broad Bean (Vcia faba)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Djoudi">A.

They were isolated from rhizosphere of a variety of broad bean grown in salt-affected soils (electrical conductivity between 4 and 8 mmhos/cm) of the irrigated perimeter of Mina in northwestern Algeria. Isolates which have advantageous results in the calcium phosphate solubilization index test were subjected to identification using API20 then used to re-inoculate the same soil in pots experimentation to assess the effects of inoculation on the growth of the broad bean (Vicia faba). Based on the results obtained from the in-vitro tests, two isolates P5 and P8 showed a significant effect on the solubilization of tricalcium phosphate with an index I estimated at 314% and 283% sequentially. According to the results of in-vivo tests, the inoculation of the soil with P5 and P8 were significantly and positively influencing the growth in biometric parameters of the broad bean. Inoculation with strain P5 has promoted the growth of the broad bean in stem height, stem fresh weight and stem dry weight of 108.59%, 115.28%, 104.33%, respectively. Inoculation with strain P8 has fostered the growth of the broad bean stem fresh weight of 112.47%. The effect of Pseudomonas on the development of Vicia faba is considered as an interesting process by which PGPR can increase biological production and crop protection. <p
