العقد الجدريةIndex. décimale : 570 بيولوجيا Résumé : The objective of the research is to evaluate the interactive effects of salinity and potassium on some physiomorphologique traits. The experiment was conducted during the development of pea seedlings (Pisum sativum L.)
var: merveille de kelvedon, the test was conducted in a randomized complete block (split plot) with three levels of NaCl (S0: 0, S1: 50, S2: 150) mMol, and two levels of potassium salt : potassium nitrate (KNO3) (N1: 20, N2: 40) mMol, and potassium acetate (CH3COOK) (A1: 20, A2: 40) mMol with four replicates grown in pots under controlled conditions, the work was executed on 48 expérimentales units.
The results are shown that treatment salts decreased significantly pigment chlorophyll (chla, Chlb, Chla+b), leaf area (Sf), the number of nodules (Nd), root length and stem (Lt, Lr) and the dry weight of shoots and roots (PSf, PSr) with increasing levels of salinity, the content of potassium (K+) and the selectivity coefficient (K+ / Na+) of leaves and roots, and the content of total nitrogen (NT) in the leaves is reduced with a high salinity concentration compared to the control , whereas the content of proline (Pro) and glucose (Glu) in the leaves and the content of sodium (Na+) in the leaves and roots have been accumulated
considerably when salinity levels are increased.
The application of the two potassium salts in the soil potassium nitrate (KNO3) or potassium acetate (CH3COOK)) is removed deleterious effects of salinity. In comparing these two potassium salts we result, the level of potassium acétate (CH3COOK) (A2) increased the number of nodules (Nd), total nitrogen (NT) in the leaves and the potassium content (K+) in the shoots and roots , but potassium nitrate (KNO3) (N2) decreased the number of nodules (Nd)
compared to the other treatment one, we can conclude that the potassium acétate (CH3COOK) is a good fertilizer than potassium nitrate (KNO3) (CH3COOK) in saline conditions.Diplôme : Magistère En ligne : ../theses/biologie/ASAI4019.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9748 أثر التداخل بين K+ / Na+ على تطور و نمو العقد الجذرية لنبات البازلاء Pisum sativum L.)) صنف merveille de kelvedon النامي تحت ظروف ملحية اثناء مرحلة نمو الشتلة [texte imprimé] / هاجر سعيد, Auteur ; سعيدة شوقي, Directeur de thèse . - constantine [Algérie] : Université Constantine 1, 2014 . - 79 ورقة. ; 30 سم.

Biologie Résumé :
Various morpho-physiological, biochemical and phonological features related to water stress tolerance (leaf area, osmotic adjustment, osmotic accumulation, root traits and date to heading) were studied in ten genotypes of durum wheat (Triticum durum Desf.) with contrasting agronomic behaviour. Significant variations between the tested genotypes were observed mainly for the relative water content, osmotic potential and the various osmoticums analysed at the symplasmic level indicating that their behaviour with respect to these osmoticums is significantly different from a degree of stress to another. The relationships between these traits and the adaptation strategies developed by each variety have been described. The classification of the genotypes studied according to their sensitivity to water stress indicates that the Cirta, Boussellam, Mohamed Ben Bachir, Bidi 17 and Wahbi genotypes have a long grain filling time, high relative water content (RWC) and are therefore efficient and tolerant to water stress. Varieties that have shown sensitivity to stress are therefore not very productive, just like the Sémito variety. This observation leads us to conclude that tolerance and great capacity of osmotic adjustment are consubstantial. Other results highlight significant negative correlations between nitrate and proline content and thus showing the probable existence of a connection between the proline biosynthesis pathway and nitrate uptake. Close relations have been observed essentially between osmotic adjustment, soluble sugar content and proline. This suggests that the osmoticum that contributes most to osmotic adjustment in order of preference are soluble sugars, proline, potassium and to a lesser degree nitrates. In case of stress, the biochemical response evaluated through the process of accumulation of proline and soluble sugars varieties (Waha, Bousselam, Mohamed Ben Bashir, Cirta and Bidi17) under water stress has proved to be a criterion of effective
adaptation. Correlations between osmotic adjustment capacity and yield show the reliable role of osmotic adjustment in water deficit tolerance. The results obtained in the fields reveal the existence of high performance, low productivity and non-performing genotypes. The duration of heading allowed classifying the early and late genotypes.Note de contenu :

morpho-physiological and biochemical parameters in order to alleviate the interaction between the Na+ / K + during the germination phase and development of tomato (Lycopersicon esculentum Mill var: Heintz ). For this purpose a factorial experiment was performed on the soil in pots in a completely randomized block design with four concentrations of NaCl (S0: 0, S1 25, S2 50 S3: 150) mmol / L and four concentrations of potassium as KH2PO4 (K0:0, K1:10, K2:20, K3:40) mmol / L with four replications under controlled conditions, the work was done on 64 experimental units. Morphological observation during the germination phase showed that salinity has a depressive effect on the germination percentage (GP) germination capacity (GC), germination rate (GR) and the germination stress index (GSI) .During the seedling development phase salt stress resulted in an increase in stomatal resistance (RS) which reflected on stomatal conductance (SC) these physiological traits are linked to the accumulation of solutes (glucose, proline ) which may be due to the
accumulation of Na+ and reduction of K+ and the selectivity coefficient Na+ / K+ in the leaves and roots that have participated in the reduction of leaf area (SF) fresh weight (PF) the dry weight (PS) the length of the stem (LN) and the rate of chlorophyll pigments (Cha, Chb, ChT) ,by against the index of salinity stress (DMSI) increased and decreased potassium Applying this last eliminated the inhibitory effect of salinity in the different proposed levels during germination stage and seedling development.Diplôme : Magistère En ligne : ../theses/biologie/AHEM4113.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10201 مقارنة التأثير الفعلي لمعاملات البوتاسيوم لإزاالة اأثثر السلبي للملوحة على عدة مظاهر فيزايوكيميائية لنبات Lycopersicon esculentum Mill Var: Heintzالطماطم [texte imprimé] / حميدة حمادي, Auteur ; سعيدة شوقي, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2014 . - 69 ورقة. ; 30 سم.
