“…A negative influence of Na + and Cl À ions on plant growth has been reported previously (e.g. Charbaji and Ayyoubi, 2004, for review see Tester and Davenport, 2003). Under in vitro conditions, olives form only calli and not roots, and the calli probably do not represent a sufficient barrier to Na + and Cl À ions entering the shoot.…”

“…pour la grande naine : l' accumulation de Mg2+ diminue régulièrement avec la concentration saline du milieu tandis que chez la petite naine on note une augmentation à 2 g/l : alors que a 4 g/l et 6 g/l la teneur de cet ions devient moins importante.

RÉSUMÉObjectifs : Le travail présenté ici a pour objectif de décrire l'effet de la salinité sur la croissance et la distribution des principaux éléments minéraux chez le bananier. Méthodologie et résultats : L'étude de l'effet de la salinité a été réalisée sur deux variétés du bananier (Musa acuminata L), la grande naine et la petite naine issues de culture in vitro. Les variétés testées ont été combinées à quatre niveaux de chlorure de sodium (NaCl) à savoir : 0, 2, 4 et 6 grammes par litre (g/l). Les résultats ont montré la réduction de la biomasse aérienne et racinaire, une accumulation de potassium dans la partie aérienne et de sodium dans la partie racinaire, ainsi qu'une réduction d'absorption de calcium et de magnésium et une légère variation d'azote dès la concentration 4g/l. Une certaine tolérance aux sels a été notée chez la variété grande naine comparativement à la petite naine. Cette tolérance pourrait être liée à une bonne sélectivité vis-à vis du potassium. Les variétés étudiées se comportent comme des plantes exclusives. Conclusion et application de la recherche : Les caractéristiques ioniques de la variété de bananier, la grande naine, diffèrent de celles de la petite naine, Les résultats obtenus confirment que l'amélioration de la productivité des bananiers au Maroc ne peut être réalisée que par des travaux destinés à élaborer un matériel génétique adapté à partir de la variété grande naine. Le choix doit s'effectuer sur la base d'un grand nombre de caractères (morphologiques, biochimiques physiologiques) contrôlant les déterminismes génétiques complexes de la tolérance à la salinité. ABSTRACTEffect of salinity on the growth of two varieties of banana Grande Naine" and "Petite Naine " and their mineral nutrition in Morocco Objectives: The present work is intended to describe the effect of salinity on the growth and distribution of major minerals in banana. Methods and results:The study of the effect of salinity was carried out on two banana varieties (Musa acuminata L), the grand Naine and the petite Naine from in vitro culture. The varieties tested were combined with four levels of NaCl (0, 2, 4 and 6 gal / l). Results showed the reduction of biomass and root accumulation of potassium in the shoot and sodium in the root. There was reduced absorption of calcium and magnesium and a slight variation from the nitrogen concentration of 4g / l. Some salt tolerance was noted in the Grande Naine compared to the petite Naine variety. This tolerance may be associated with a good selectivity towards potassium. Conclusion and application of research: ionic characteristics of the banana variety, the Grande Naine differs from the petite Naine. The results confirm that improvements in the productivity of banana in Morocco should be achieved by work to develop Grande Naine germplasm by the use of a large number of characters (morphological, biochemical, physiological) controlling complex genetic determinism of salinity tolerance

“…Furthermore, the in vitro selection of cells able to be propagated in highly saline conditions opens the way for investigations of plant metabolism as well as the mechanisms involved in salt tolerance at the cellular level (e.g. Piqueras et al 1996;Charbaji and Ayyoubi 2004).…”

The changes in lipid peroxidation and the involvement of the antioxidant system in relation to salt stress tolerance were investigated in the callus of Acanthophyllum glandulosum and Acanthophyllum sordidum. The callus was subjected to NaCl stress (50-200 mM) for 40 d. The callus of A. glandulosum was less sensitive to NaCl stress than that of A. sordidum. Increasing concentrations of NaCl from 50 to 200 mM correlated to increased proline content in A. glandulosum. Total protein content was higher in extracts of A. glandulosum than in extracts of A. sordidum under both control and salinity treatments. Compared with A. sordidum, lipid peroxidation and H 2 O 2 content were lower and the activities of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPX), ascorbate peroxidase, and glutathione reductase were higher in A. glandulosum under salt stress. Activity staining of antioxidant enzymes separated by native polyacrylamide gel electrophoresis (PAGE) revealed that callus of A. sordidum had five Fe-SOD isoforms and one Mn-SOD isoform, all of which were reduced by salinity. In A. glandulosum, two Mn-SOD, three Fe-SOD, and one Cu/ Zn-SOD isoforms were detected. Out of these six SOD isoforms, expression of the Mn-SOD and Fe-SOD isoforms was enhanced at 100 mM and higher NaCl concentrations. Two and six GPX isoforms were detected in A. sordidum and A. glandulosum, respectively. Expression of the single CAT isoform in A. sordidum was preferentially reduced by salinity. In A. glandulosum, the two CAT isoforms showed differential down regulation under NaCl stress, with the CAT2 isoform detected only under control condition. These results suggest that A. glandulosum callus is better protected against salinity-induced oxidative damage by maintaining higher activities of antioxidant enzymes than the callus of A. sordidum.
