“…On the other hand, with increasing salinity, LIL significantly increased in Shishe (Table 3). It agreed with results in strawberry (Kaya et al 2002a, Khayyat et al 2009a, olive (Goreta et al 2007, Perica et al 2008, and Echinacea (Sabra et al 2012). In some species, membrane permeability changed before the growth reduction or before the appearance of severe chlorosis (Lutts et al 1996, Mansour andSalama 2004).…”

The present research was conducted to assess physiological responses of 'Malas-e-Saveh' (Malas) and 'Shishe-Kab' (Shishe) pomegranates to water of different salt content and electrical conductivity (1.05, 4.61, and 7.46 dS m −1). Both cultivars showed a reduced trunk length due to salinity. Relative water content and stomatal conductivity of both cultivars were significantly reduced under salt stress, but ion leakage increased. In both cultivars, total chlorophyll (Chl) and carbohydrates decreased with rise in salinity, while proline accumulation increased. With salinity increment, the Chl fluorescence parameters (maximum photochemical efficiency of PSII and effective quantum yield of PSII) declined significantly in both cultivars, with higher reduction observed in Shishe. Generally, more Na + accumulated in shoots and more Cl − was observed in leaves. Cl − accumulation increased by salinity in leaves of Malas, but it was reduced in Shishe. The K + /Na + ratio in leaves decreased in both cultivars by salinity increment. Malas was less affected by osmotic effects of NaCl, but it accumulated more Cl − in its leaves. Thus, Malas might be more affected by negative effects of salinity.

“…This observation was confirmed by their biomass, as the latest is the most well-known effect of these stresses Nebauer et al, 2013;Perica et al, 2008), considering that a decline of AN can be considered one of the main reason of growth reduction James et al, 2008;. In fact, in our experiments grafted plants onto tolerant accessions an absence of negative effects on plant growth was realized, correlated with a maintenance of AN.…”

Noviembre 2015 Programa de Doctorado en Recursos y Tecnologías Agrarias I | SUMMARYPepper is a vegetable of extraordinary economic and social importance in our country. Unfortunately, the persistent exploitation of the land, the monoculture and the intensification of production processes, lead to the development of soil diseases. This coupled with the abiotic stress, mainly the salinity of waters and soil, suboptimal temperatures and water stress, can induce the appearance of physiological disorders in peppers as the Blossom-end rot (BER) and cracking or cracked, induce plant senescence and decrease not only production, but also the quality of the product. Salinity and water shortages are two among the biggest environmental problems that crops have to face in the Mediterranean area. A way to overcome the stresses under the prism of an ecological or integrated crop management, is the use of grafted plants as adaptation strategy. Although there has been remarkable progress in this technique (mainly in tomato, melon, watermelon), in the cultivation of pepper use remains rare. In this Doctoral thesis several pepper genotypes have been selected through different physiological parameters which indicate tolerance to salt and water stress. Commercial cultivars were grafted onto the selected genotypes and were grown under water stress, salinity and control conditions studying several physiological, agronomic responses and the interaction rootstock/scion.The results obtained concluded that genotypes selected and used as rootstocks improved commercial varieties to salt and water stress tolerance, both in terms of performance (commercial production) compared to other commercial characters and variety without grafting. Different physiological mechanisms explain the tolerance to stress, such as the ability to maintain the water potential through an osmotic adjustment, stimulation of the antioxidant system, exclusion II | or retention of toxic ions (Na + and Cl -) in saline in the roots and the maintenance of photosynthesis which allows to maintain the metabolic functions of grafted plants and production. III | RESUMENEl pimiento es una hortaliza de extraordinaria importancia económica y social en nuestro país. Lamentablemente, la persistente explotación del suelo, el monocultivo y la intensificación de los procesos de producción, conducen al desarrollo de enfermedades del suelo. Esto unido a los estreses abióticos, principalmente la salinidad de las aguas y del suelo, temperaturas subóptimas y estrés hídrico, puede inducir la aparición de fisiopatias en el pimiento como el Blossom-end rot (BER) y cracking o rajado, inducir senescencia vegetal y disminuir no solo la producción, sino también la calidad del producto.La salinidad y la escasez de agua son unos los mayores problemas medio ambientales a los que tienen que hacer frente los cultivos en el área Mediterránea. Un modo de sortear los estreses bajo el prisma de un manejo integrado o ecológico del cultivo, es la utilización de plantas injertadas como estrategia de adaptació...

“…The Cl -contents in leaves and roots in the study of Kchaou et al (2010) were greater than those found in the present study. Although genotypic differences between olive cultivars have been documented Perica et al, 2008), the main reason for the difference may be the type of stress applied; Kchaou et al (2010) only varied the concentration of NaCl, whereas the stress applied in this study combined 200 mM NaCl with 0.49 mM boron.…”

-contents in 8 accessions of olive. Rooted one-year-old plants were cultivated for 132 days with 50% shading in 5-L pots containing sand substrate and watered with Jensen's nutrient solution. After eight days of uniform ferti-irrigation, the plants were exposed to saline-boron stress, which was administered in three successive stages to condition them to a final stress of 0.49 mM B(OH) 3 and 200 mM NaCl. The accessions were identified by their place of origin as Suca, Chiza, San Pedro I (SPI), Taltal, Azapa, San Pedro II (SPII), Frantoio and Lluta. The results showed that saline-boron stress decreased vegetative growth and dry matter in all accessions. The levels of Cl -in leaves and roots increased significantly, although Suca and SPI experienced the least increases. B increased in leaves and roots but did not reach toxic levels. Water potential decreased except in the accession Taltal. RWC decreased in all accessions. Cv. Frantoio, known internationally for its high salt tolerance, was used as a reference for the observed responses in the other accessions.
