| 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... |

| 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... |

| 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... |

| 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... |

| 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... |

| 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... |

| 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... |

| 羊草の耐塩性が体内の塩濃度に由来するかについて,塩ストレス下においてペレニアルライグラス(耐塩性)およびメドウフェスク(塩感受性)と比較して調べた。羊草地上部のナトリウム(Na)濃度は他の2草種より低く,Naの排出速度は他の2草種よりわずかに高かった。地下部においては,羊草のNa濃度は他の2草種とほぼ同じであったが,Naの吸収および排出速度は他の2草種より極めて低かった。このとき,吸収と排出速度の差は他の2草種より小さかった。以上の結果,羊草の耐塩性は,地下部での塩の低吸収および効率的排出と,これらに起因する地上部での塩の低蓄積によるものと考えられる。 Reduction of plant sodium level as a means of salt tolerance of Chinese wild rye (Aneurolepidium chinense (Trin.) Kitag.) was investigated under salt stressed condition as compared with perennial ryegrass (salt tolerant) and meadow fescue (salt sensitive). Sodium concentration in the top portion of Chinese wild rye was lower than those in other two grasses, while the excretion rate in the rye top was only slightly higher. Sodium concentration in the root of the rye was similar to... |

| Abstract Cowpea crop is of great importance for northeast Brazil. The objective of this work was to evaluate the application of saline water in different developing stages on plant growth and changes in soil characteristics, measured by soil coverage, and on yield of cowpea plants. The experiment was conducted under field conditions, during the dry season in a completely randomized block design with five treatments and five replications. Each experimental unit consisted of 4 lines of plants with 5.0 m long. The treatments evaluated were: 1. irrigation with groundwater with electrical conductivity (ECw) of 0.8 dS m-1 during the whole crop cycle; 2. saline water (5.0 dS m-1) during the whole crop cycle; 3, 4 and 5. saline water (5.0 dS m-1) up to 22nd,... |

| The present study was conducted to evaluate salt tolerance in seven different pure-line cultivars of tomato (Solanum lycopersicum L.) viz. K-21, Pusa Ruby, Pusa Gorav, Hera research, Selection N5, PKM-1 and S-22 based on several physiological and biochemical traits. Seedlings were transplanted to the pots, being exposed to different salinity levels in the form of NaCl (0, 50, 100, or 150 mM) at a 35-day stage of growth for six days. The plants exposed to salt stress presented a significant decline in growth, photosynthetic parameters, maximum quantum yield of PSII and leaf water relations, which were drastically reduced in variety S-22, while variety K-21 was the least affected. Electrolyte leakage was superior in proportion to an increase in salinity... |

| ABSTRACT The development of agriculture in the northeastern semi-arid region depends, at least in part, on the correct exploitation and efficient use of natural resources. The objective of this study was to evaluate the effects of the use of saline water on morphophysiological responses and sensory analysis of ‘Boa noite’ plants (Catharanthus roseus) in soil fertilized with bovine biofertilizer. A completely randomized design was used in the split plot arrangement, the plots being formed by the five irrigation water salinity levels (0.5, 2.5, 5.0, 7.5 and 10 dS m-1), and the subplots by two frequencies of application of the 150 mL pot-1 of liquid bovine biofertilizer (divided into one and five times), with five replicates. The analysed variables were: leaf... |

| ABSTRACT Biosaline agriculture is an option for using waters with lower quality. Thus, the objective of this study was to evaluate the growth of ornamental species under irrigation with increasing water salinity levels in two methods of water application. The study was conducted in a greenhouse, in the municipality of Fortaleza, Ceará, Brazil. The treatments were distributed in randomized blocks in split plots, with six levels of water salinity in the plots (0.6 - control, 1.2, 1.8, 2.4, 3.0 and 3.6 dS m-1), two methods of water application in the subplots (localized and sprinkler irrigation) and four ornamental species in the sub-subplots (Catharanthus roseus, Allamanda cathartica, Ixora coccinea and Duranta erecta), with four replicates. Increase in... |

| Chicory plants, cv. 'Amarelo' and 'Pão de Açúcar', were grown hydroponically under four NaCl concentrations in the nutrient solution to determine its tolerance to salinity. Sowing was made in rows placed 0.05m apart, on a 0.15m deep sand growing bed placed over fibber cement tiles. After emergence, plants were thinned to a plant density of 1,600plants m-2. A standard nutrient solution was used, with the main composition of, in mmol L-1, 13.5 NO3-; 2.5 NH4+; 1.5 H2PO4-; 1.5 SO4--; 7.5 Ca++; 10.0 K+ and 1.5 Mg++. The control (T1) was the standard nutrient solution, without addition of NaCl. Four salinity levels were compared, by adding 0.697 (T2), 1.627 (T3), 2.556 (T4) and 3.485 (T5)g L-1 of NaCl. The nutrient solution was delivered to plants four times a... |

| ABSTRACT Rugosa rugosa has high tolerance to various stresses; however, the molecular mechanisms of this behavior under adverse conditions are unclear. The objective of this study is to investigate expression patterns of stress-related genes in response to salinity stress. Changes in transcript levels of R. rugose, grown under different salt stress conditions (0, 25, 50, and 100 mM NaCl) over a long exposure period (30 days), have been investigated. In addition, the effects of salt shock stress on seedlings exposed to a high level (200 mM) of NaCl for a relatively short duration (3 h) have also been investigated. Expression levels of selected differentially expressed genes have been determined using relative reverse transcription polymerase chain reaction... |

| Irrigation with water containing salt in excess can affect crop development. However, management strategies can be used in order to reduce the impacts of salinity, providing increased efficiency in the use of good quality water. The objective of this research was to study the effects of use of high salinity water for irrigation, in continuous or cyclic manner, on vegetative growth, yield, and accumulation of ions in maize plants. Two experiments were conducted during the months from October to January of the years 2008/2009 and 2009/2010, in the same area, adopting a completely randomized block design with four replications. Irrigation was performed with three types of water with electrical conductivities (ECw) of 0.8 (A1), 2.25 (A2) and 4.5 (A3) dS m-1,... |
