“…This behavior which was observed in all the grafted plants, was more pronounced when RS-841 was used as rootstock genotype, and thus RS-841 cultivar exhibited an apparently higher resistance to Cl-than the remaining rootstock genotypes. Our results agree with those of other authors who reported that leaf pigments can be used as possible indicators of the degree of salt tolerance in grafted citrus trees (Zekri and Parsons 1989;Nieves et al 1991).…”

“…Nieves et al (1991) have reported more reductions in chlorophyll contents of ''Fino lemon'' than in ''Verna lemon'' under salt stress. In the present study, net rate of photosynthesis dropped sharply with the application of salinity treatment.…”

“…Regulation of proline in citrus is atypical of glycophytes. Under conditions where growth of citrus is affected by an imposed salinity, the elevation in the proline level is less than twofold (Nieves et al 1991;Walker et al 1993) or there is no proline response (Syvertsen and Yelenosky 1988;Lloyd et al 1989) indicating that it is not a by-product of stress (Storey and Walker 1999). Stress has been shown to alter the polyamine titer in various plants (Smith 1990).…”

Six-months-old, uniform sized seedlings of two citrus rootstocks; Cleopatra mandarin (Citrus reshni Hort. ex Tan) and Troyer citrange (Poncirus trifoliata · Citrus sinensis) were irrigated with half-strength Hoagland nutrient solution containing 0, 40 or 80 mM NaCl for 12 weeks. Shoot height, leaf number and fresh weights of the seedlings, and relative chlorophyll contents, chlorophyll fluorescence yields (Fv/Fm), net photosynthetic and respiration rates in the leaves decreased with the increase in salinity level in the irrigation water. The decrease was greater in Troyer citrange as compared to Cleopatra mandarin. The concentrations of sugars i.e. fructose, glucose and sucrose in the leaves of Cleopatra mandarin and both leaves and roots of Troyer citrange decreased with the increase in salinity level. However, the concentrations in the roots of Cleopatra mandarin increased with the increase in salinity level. Free proline content in the leaves of Troyer citrange and root tissue of Cleopatra mandarin also increased with the increased salinity level. Among the polyamines, spermine titer increased in the leaves of both rootstocks as a response to salinity treatments. Na + concentrations were higher in leaf and root tissue of Cleopatra mandarin, while that of Cl À were higher in Troyer citrange.

“…Ces résultats vont dans le même sens que ceux obtenus par Fernandez-Ballester et al [8] selon lesquels une irrigation saline augmenterait légèrement mais non significativement le taux de cet acide aminé dans les feuilles. D'autres auteurs [16] ont rapporté qu'une accumulation de proline serait une caractéristique du porte-greffe. Cependant, selon Hubac et Gerruer [17], la proline ne serait pas la conséquence d'un stress, mais plutôt métabolisée comme facteur de tolé-rance.…”

Effect of saline stress on proline and soluble sugar accumulation in three citrus rootstock leaves in Morocco.Abstract -Introduction. Soil salinity and irrigation water, worsened by the rarity of rainfalls, are a permanent threat to the cultivation of citrus trees in Morocco. The choice of a rootstock able to tolerate this abiotic stress would be an effective means of attenuating this problem. The experimentation presented aimed to evaluate three citrus rootstocks recently introduced to Morocco, regarding saline stress. Materials and methods. Seedlings of citrange Carrizo and two hybrids, H1 and H2, resulting from the crossing (Poncirus trifoliata´Citrus sunki Hort. ex Tan.) were evaluated for their tolerance to salinity. The 18-month-old seedlings were irrigated by a nutritive solution containing (25, 35, and 70) mM of NaCl for one or two months, whereas the control seedlings received the nutritive solution without NaCl. After treatment, the proline and soluble sugar contents were measured in the leaves of the treated rootstocks. Results. The accumulation of proline was independent of the presence of NaCl in the irrigation solution but it varied according to the rootstock genotype. On the other hand, NaCl strongly stimulated the accumulation of soluble sugars in the three rootstocks and this accumulation was very significant in the citrus rootstock H1. Discussion and conclusions. These results agree partly with some of the work already published. Under our experimental conditions, the effect of the NaCl concentrations used could be compensated by the storage of soluble sugars in the leaves, in particular in those of the rootstock H1. As this showed less foliar toxicity than the two other rootstocks, the soluble sugar storage in the citrus leaves could indicate a tolerance to salinity.Morocco / Citrus / rootstocks / salt tolerance / leaf extracts / sugars / proline Effet du stress salin sur l'accumulation de la proline et des sucres solubles dans les feuilles de trois porte-greffes d'agrumes.Résumé -Introduction. La salinité du sol et de l'eau d'irrigation, aggravée par la rareté des précipitations, est une menace permanente pour la culture des agrumes au Maroc. Le choix d'un porte-greffe tolérant à ce stress abiotique serait un moyen efficace pour pallier ce problème. L'expérimentation présentée a permis d'évaluer, vis-à-vis du stress salin, trois portegreffes récemment introduits au Maroc. Matériel et méthodes. Des plants de citrange Carrizo et de deux hybrides, H1 et H2, issus du croisement Poncirus trifoliata x Citrus sunki Hort. ex Tan. ont été évalués pour leur tolérance à la salinité. Les plants âgés de 18 mois ont été irrigués par une solution nutritive additionnée de (25, 35, et 70) mM de NaCl durant un ou deux mois alors que les plants témoins recevaient la solution nutritive sans NaCl. Après traitement, les teneurs en proline et en sucres solubles ont été mesurées dans les feuilles des porte-greffes traités. Résultats. L'accumulation de proline a été indépendante de la présence de NaCl dans la solutio...
