“…Urban the decrease in Vs exceeded the lowering of external Us due to NaC1 which is presumably due to more accumulation of salt by roots (Munns 1993). This result is consistent with our previous finding in subepidermal cells of leaf sheath and coleoptile of wheat and barley under salt stress (Mansour et al 1993b). Organic osmotics (betaine/proline) and ions might be also the contributors to the decrease in Us (Greenway and Munns 1980).…”

“…Salinity stress has been reported to disturb the integrity of wheat and barley cell membrane resulting in increased membrane permeability and decreased lipid partiality (Mansour et al 1993a). In previous work and other studies (Mansour 1990, Mansour et al 1993b) genotypic differences in response to NaCI stress were reported. In the previous study subepidermal cells of leaf sheath and coleoptile of wheat and barley were used to test the effects of salinity stress on cytoplasmic factors.…”

10-d-old wheat seedlings were grown hydroponically in presence and absence of 100 mM NaCI for 7 d. Salt stress decreased growth of shoots and roots of both cultivars; fresh mass of sensitive cultivar being more affected. NaCI increased membrane permeability to urea, methylurea and ethylurea and decreased membrane partiality in root cortex cells of sensitive cultivar. Neither parameter changed by NaC1 in resistant cultivar. NaCI treatment decreased water permeability and osmotic potential in both cultivars; sensitive cultivar was more affected. The results extends our previous data that cell membrane properties are different in salt sensitive and resistant genotypes and so cell permeability could be a potential trait indicating salt tolerance.

“…Nos travaux (Ben Khaled et al, 2003) ont montré que le NaCl a induit une désorganisation des membranes thylakoïdiennes et une accumulation de l'amidon et des globules lipidiques au niveau des chloroplastes d'une légumineuse fourragère. Chez le blé et l'orge, le sel peut altérer certaines structures cytoplasmiques comme les microtubules, les microfibrilles, les sphérosomes et les ribosomes (Mansour et al, 1993a).…”

L'application d'un stress salin à des pieds de blé dur (Triticum durum Desf. «Massa ») cultivés en milieu hydroponique pendant 16 jours affecte la croissance et le statut nutritionnel des plants. Cet effet est marqué par un retard du tallage, une diminution de la biomasse sèche, une réduction de la surface foliaire, de la longueur des racines et l'apparition des perturbations des équilibres ioniques. À 50 mM, la biomasse sèche de la partie aérienne a été réduite de 59% et celle des racines de 52%. L'effet dépressif du NaCl s'est accompagné également de modifications nutritionnelles. Le sel induit une accumulation des ions potentiellement toxiques (Na + et Cl-) de façon plus prononcée dans les feuilles que dans les racines. En même temps, le NaCl perturbe plus l'absorption et le transport du potassium et du calcium dans les parties aériennes que dans les racines. À 25 mM, la teneur en K + au niveau des organes aériens ne représente plus que 70% par rapport aux témoins. De même, la teneur en calcium dans ces organes chute très fortement (5 fois que celle des témoins). Ces manifestations sont révélatrices d'une sensibilité particulière de la variété Massa à la salinité.

“…deliciosa) under B toxicity was due to the decrease of photosynthetic rate, volume of mesophyll cells, and cell damage (Sotiropoulos et al, 2002). Salinity also induced anatomical changes in cells, including decreased cell size, protoplasmic swelling, and inhibition of growth and xylem differentiation (Mansour et al, 1993).…”

The objective of the present research was to study the effects of boron (B) and potassium chloride (KCl) induced salinity on growth, nutritional status, and chlorophyll content of the cherry rootstocks CAB 6P (Prunus cerasus L.) and Gisela 5 (Prunus cerasus L. × Prunus canescens L.). Plants produced the longest shoots, more leaves, and the greatest fresh weights of shoots and leaves when treated with 0.025 mM B combined with the lower level of salinity (0.75 dS m −1 ). CAB 6P plants retained most of their leaves until the end of the experiment, whereas Gisela 5 plants showed higher leaf shedding. Irrigation of plants with solutions containing 0.2 mM B and electrical conductivities (EC) of 4 dS m −1 resulted in lower leaf chlorophyll contents (SPAD units) when compared with all other treatments. Nitrogen (N) concentrations of leaves from both rootstocks decreased as the EC of the nutrient solution increased from 0.75 to 4 mM. Potassium (K) concentrations of leaves from both rootstocks increased as salinity levels increased.
