The objective of this work consists in evaluating the effect of a hydrous deficit created using a restriction of irrigation for a period of twenty (20) days on two durum wheat genotypes (Triticum durum Desf.): Gamgoum Rekham ( GGR) and Haurani; two genotypes of common wheat (Triticum aestivum L.): Florence Aurore 8193 (FA) and Mexipak and two genotypes of barley (Hordeum vulgare L.): Manel and Saida 183 and to follow the impact of this controlled stress after 24 hours (APR1) and one week (APR2), following the return of watering. A first experiment is carried out in order to compare the relation between Proline and chlorophyll, the application of prolonged hydric stress causes an accumulation of the content of proline in the leaves of the two kinds tested compared to that of their witnesses. However, this accumulation is in favor of the Triticum kind beside the Hordeum kind with a remarkable
diversity within the different varieties. As for the total chlorophyll composition of the organs studied, it evolves in a sawtooth pattern that does not lead to any indicative trend during the various treatments. After rehydration, there is a progressive decrease in proline content (APR1 and APR2), particularly at the two barley genotypes, and any change concerning the chlorophyll content. One second experimentation is carried out on the same genotypes with the same hydric treatments but this time to determine the influence of the oxydative stress produced by the dryness on the antioxydant metabolism. We were particularly interested in the activity of the superoxyde dismutase (SOD), malonedialdéhydes (MDA) content, catalase (CAT), peroxidases content (POD), as well as the ascorbate peroxidases (APX), and the content of proteins, aiming to characterize varieties according to their defense mechanisms against the effects of free radicals induced by water stress more precisely during the most critical stage and more affected by this Lack (heading stage) and to evaluate the impact of the oxydative
defensive system (Indicators of oxidation and antioxidant enzymes activities) on the synthesis and the degradation of the proline in order to identify the elements of the signaling pathways involved, and to evaluate the effect of this stress on the synthesis of this compound since the precursor molecules and its fate after the return of watering.Note de contenu :

Biologie Résumé :
The study realized at the Laboratory of Development and Valorization of Plant Genetic Resources, is conducted on species of Angiosperm families. This study aims to describe some examples of selected plants in relation to their economic interest. It is particularly related to the study of floral morphology and its main variations especially the description of the floral pieces and the characteristics of the pollen grains as well as the estimation of their viability. After collecting flowers of economic interest species, we proceeded to their study. The observations focused on morphology with the eyes first then with binocular on the reproductive organs and particularly on the pollen grains. The results obtained give a great variability as well in the organization of the flower from the point of view of number, color of pieces, number, shape and ornamentation of pollen grains as their viability evaluated by Alexander's coloration and in vitro germination. In fact, the number of floral pieces makes it possible to distinguish 3 categories of plants: Trimers species: Poaceae (Triticum durum Desf.), tetramers species : Oleaceae (Olea europea L.) and pentamers species: Rosaceae (Prunus armeniaca L.). The color of the flowers that can spread from white (Prunus cerasus L.) to red (Punica granatum L.) while passing from one species to another; The number of stamens by flower varies from 1 to infinite. It is often characteristic of the family or genus. When it is less than 10; They are most often free (Rosaceae). They can be welded by their anthers: Composeae and Cucurbitaceae ( Cucurbita pepo L.). The presence of fuzz helps protect the eproductive organs (stamens and pistils) species that bloom at low temperatures. The microscopic observation of the pollen grains gives off the oval shape (Fabaceae), round: Poaceae (Triticum aestivum L.) and triangular: Rosaceae. Pollen grains can be tricolor with an exine psilate (Rosaceae); round in shape, with exine psilate (Poaceae); oval in shape, with exine chinate (Asteraceae) and for the Lamiaceae family: the pollen grains have an oval shape, they are zonacolpe, with exine psilate. The mode of dispersion determines the number of pollen grains produced.
• Anemophilous species produce a considerable number of pollen grains to increase their chances of breeding (Phoenix dactylifera L., Cucumis sativum L., Vicia faba L., Pisum sativum L.). These are small and smooth. • Species that use insects to transport pollen (entomophilous species) produce fewer pollen grains that are sticky, larger and with thorns: species of the family Asteraceae (eg: Cynara scolymus L.) Finally, our results showed that Alexander staining is not the most reliable method for estimating pollen viability. With regard to in vitro germination it was possible to obtain a reliable estimate of the ability to germinate. Germination rates observed after one month of pollen conservation ranged from 7% to 33%.Diplôme : Doctorat En ligne : ../theses/biologie/BOU7491.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=11323 Biologie florale et diversité pollinique chez certaines Angiospermes d’intérêt économique.

مبيد الأعشاب-الغليفوسات-بقاء الفعالية-النبات المختبرIndex. décimale : 570 Sciences de la vie. Biologie Résumé : This work is a contribution to the evaluation of the persistence of the herbicide glyphosate in vegetable crops based on physico-chemical characteristics of the soil.
Soil samples with increased crops inside greenhouses and untreated soil outside of greenhouses are taken in two places of Jijel. The persistence of the herbicide was evaluated by the use of a biological test applied to radish (Raphanus sativus L.) which is selected as a test plant.
The results obtained in pots showed a delay in seedling emergence in soil collected inside greenhouses, and a decrease in the number of seedlings for the same soil, and this according to the date of application of product, the soil and the soil horizon considered.
In the first test for soil of Jimar, if sowing is practiced in soils taken from inside greenhouses after a short period of time of herbicide application (15 days) , a delay is recorded lift and lower the number of seedlings raised at the first horizon 0-10 cm for the first greenhouse in the three horizons for the second emissions. If seeding is performed after a longer time (1 month), delayed emergence and reduced number of seedlings in deep horizons 20-30 cm for soils of Jimar which are mostly silty clay soil was observed -sandy or sandy loam to some. While after three months, the same results were observed at the horizon 10 -20 cm in soils of El-Kennar which are sandy loam soils in the majority and silty clay and sand for the rest.
These results emerge as a result of the herbicide that is not retained by the non-clay soils low in organic matter, two components that should adsorb glyphosate and make it little bit mobile and inactif.
We must indicate that the biological test is not sufficient on its own. It must be supported by chemical analysis to confirm the persistence of this herbicide.Diplôme : Magistère En ligne : ../theses/biologie/NAI6436.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9463 Evaluation de la rémanence de l’herbicide Glyphosate dans les cultures maraîchères de la wilaya de Jijel [texte imprimé] / Fatima Naili, Auteur ; Mostefa Benlaribi, Directeur de thèse . - constantine [Algérie] : Université Constantine 1, 2014 . - 132 f. ; 30 cm.
