Argentinean cultivars of Vitis vinifera grow better than European ones when cultured in vitro under salinity Biocell
Cavagnaro,Juan B.; Ponce,María T.; Guzmán,Javier; Cirrincione,Miguel A..
Argentinean Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making. In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabernet Sauvignon and Chardonnay and four Argentinean cultivars, Cereza, Criolla Chica, Pedro Gimenez and Torrontes Riojano were tested by in vitro culture. Treatments included: 1) Control, 2) 60 mEq/L of a mixture of three parts of NaCl and one part of CaCl2 and 3) 90 mEq/L of the salt mixture. Results from two experiments (I and II) are reported. No differences were...

Changes in physiological indicators associated with salt tolerance in two contrasting cashew rootstocks Braz. J. Plant Physiol.
Ferreira-Silva,Sérgio L.; Silveira,Joaquim A.G.; Voigt,Eduardo L.; Soares,Lucilene S.P.; Viégas,Ricardo A..
In order to identify salt tolerance indicators, several physiological variables were evaluated in two contrasting cashew (Anacardium occidentale L.) rootstocks in response to salt stress. The tolerant CCP 09 genotype showed better growth performance after two weeks under a large range of NaCl salinity (50, 100, 150 and 200 mM). The NaCl treatments induced a significant drop in transpiration as a consequence of an increased stomatal resistance in both genotypes. No significant differences in Na+, Cl, and K+ concentrations were found in both roots and leaves regardless of rootstocks. The tolerant genotype exhibited lower relative water content and less negative leaf osmotic potential as compared with the sensitive genotype and, therefore, these variables...

Crescimento e acúmulo de cátions em plantas de moringa mantidas em solos salinos PFB - Pesquisa Florestal Brasileira
Freire, Antonio Lucineudo Oliveira; Miranda, José Romilson Paes de.
Com o objetivo de avaliar os efeitos da salinidade no crescimento e acúmulo de massa seca e cátions em plantas jovens de moringa (Moringa oleifera), testaram-se quatro tipos de solos, nas condutividades elétricas (C.E.) 0,49 (controle), 4,15, 6,33 e 10,45 dS m-1. O experimento foi conduzido em delineamento inteiramente casualizado, com quatro repetições. As plantas cresceram inicialmente em tubetes rígidos e, aos 30 dias após a emergência, foram transferidas para vasos contendo 10 kg de solo, de acordo com o tratamento de salinidade. A salinidade prejudica o crescimento inicial das plantas e acúmulo de cátions na parte aérea e nas raízes das plantas. Na fase inicial de crescimento, as plantas de moringa não inibem a absorção de Na e sua translocação para a...

Effect of Salinity and Nitrogen Form in Irrigation Water on Growth, Antioxidants and Fatty Acids Profiles in Halophytes Salsola australis, Suaeda maritima, and Enchylaena tomentosa for a Perspective of Biosaline Agriculture ArchiMer
Certain, Cassandre; Della Patrona, Luc; Gunkel-grillon, Peggy; Leopold, Audrey; Soudant, Philippe; Le Grand, Fabienne.
Cultivation of salt-tolerant crops help to face to irreversible global salinization of freshwater and soils. In New-Caledonia, three halophytes are candidates for saline crops, Salsola australis R.Br., Suaeda maritima (L.) Dumort and Enchylaena tomentosa R.Br. Their success and quality depend yet on availabilities of salinity and essential nutrients in agrosystems. So, we investigated effects of three salinities, i.e., control moderate and high, and five nitrogen ratios, i.e., 100:0, 75:25, 50:50, 25:75 or 0:100 NO3−-N:NH4+-N ratio on their growth and functional value for fatty acids and antioxidants. Results show that the leaf fatty acid and antioxidant profiles of species, emphasize their good potential to become functional crop products, based on...

EFFECTS OF SALINE WATER ON TOMATO UNDER SUBSURFACE DRIP IRRIGATION: NUTRITIONAL AND FOLIAR ASPECTS J. Soil Sci. Plant Nutr.
Kahlaoui,B; Hachicha,M; Rejeb,S; Rejeb,M.N; Hanchi,B; Misle,E.
A field experiment on the effects of drip irrigation (DI) and subsurface drip irrigation (SDI) with saline water (6.57 dS m-1) on three tomato cultivars (Lycopersicon esculentum Mill., cvs. Rio Tinto, Rio Grande and Nemador) was carried out with the purpose to quantify physiological responses. The aim was to improve irrigation water management under saline conditions of Tunisia. The trial was established in a silt-clayey soil with three regimes of irrigation: 100 %, 85 % and 70 % of crop water requirement. Results evidenced a significant difference between the two irrigation systems for the three cultivars. Growth parameters such as leaf area, chlorophyll content and mineral composition of leaves, petioles, stems and roots were affected significantly by...

Germination responses of Lycium humile, an extreme halophytic Solanaceae: understanding its distribution in saline mudflats of the southern Puna Acta Botanica
Palchetti,María Virginia; Llanes,Analía; Reginato,Mariana; Barboza,Gloria; Luna,Virginia; Cantero,Juan José.
ABSTRACT Although knowledge about halophytic Solanaceae is scarce, it is known that several species within genus Lycium tolerate salinity. Lycium humile grows in highly saline soils in mudflats near saline Andean lakes. This study evaluated the germination responses of L. humile under different scarification methods, photoperiods, temperatures and saline conditions and, simultaneously, tested seedling survival under different iso-osmotic conditions. Dormancy and germination were found to be regulated by interactions with different factors, with the highest germination percentages being obtained by immersion in sulfuric acid, with a temperature of 25 °C and a temperature regime of 5/25 °C, under which seeds were neutrally photoblastic. As osmotic potential...

Impacts of saline stress on the physiology of Saccharum complex genotypes. Repositório Alice
SIMOES, W. L.; OLIVEIRA, A. R. de; TARDIN, F. D.; OLIVEIRA, C. P. M. de; MORAIS, L. K. de; TEODORO, L. P. R.; TEODORO, P. E..
Knowledge of the physiological mechanisms in saline environment may boost sugarcane breeding programmes targeting abiotic stresses. Our hypothesis is that the physiology of Saccharum genotypes responds differently under salt stress. Thus, the objective of the study was to evaluate the physiological performance of Saccharum complex genotypes grown under presence and absence of saline stress. The experimental design used was randomized blocks arranged in a 32 × 2 factorial scheme (32 genotypes × 2 salinity levels). The presence of salinity provided higher mean values for photosynthetic rate in genotypes G4, G18, G22, G25 and G29 compared with the environment without salinity, with mean values (17.26, 21.49, 24.22 and 26.19 µmol CO2m?2s ?1), respectively, for...

Isolation and partial purification of beta-galactosidases from cotyledons of two cowpea cultivars Rev. Bras. Fisiol. Veg.
ENÉAS-FILHO,JOAQUIM; BARBOSA,GISLAINY KARLA DA COSTA; SUDÉRIO,FABRÍCIO BONFIM; PRISCO,JOSÉ TARQUÍNIO; GOMES-FILHO,ENÉAS.
Three isoforms of beta-galactosidases were isolated and partially purified from the cotyledons of quiescent seeds of Vita 3 and Vita 5 cowpea [Vigna unguiculata (L.) Walp.] cultivars differing in water and salt stress tolerance. The purification procedure consisted of ammonium sulfate fractionation, acid precipitation, ion exchange chromatography through DEAE-sephadex and affinity chromatography through Lactosyl-sepharose columns. The three isoforms isolated from the two cultivars showed the same chromatographic patterns, same optimum of temperature for enzyme activity assay (60ºC), identical thermal stability up to 50°C, and similar pH optima (3-4). However, they differed from each other in sensitivity towards metal ions and certain chemical agents...
