“…Osmotic adjustment in olive leaves under salt stress was accomplished primarily by accumulation of inorganic ions, despite the osmotic contribution by soluble carbohydrates. Although our measurements did not account for some classes of osmotically important compounds, their relative osmotic contribution can be estimated from data reported in the literature (Tattini et al 1993, Heimler et al 1995. Leaf Cl − concentration was close to that of Na + (Bongi and Loreto 1989, Tattini et al 1992, Heimler et al 1995, with presumably comparable osmotic effects.…”

“…Leccino plants initially had a higher net solute accumulation than Frantoio plants, but the two cultivars had similar values of net solute accumulation at the end of the salinization period (Table 2). Differences in the lipid composition of root cell membranes may partially explain the different ion-exclusion capacities of the two cultivars during salt stress (Heimler et al 1995). Osmotic adjustment in olive leaves under salt stress was accomplished primarily by accumulation of inorganic ions, despite the osmotic contribution by soluble carbohydrates.…”

One-year-old rooted cuttings of olive (Olea europaea L. cvs. Frantoio and Leccino) were grown either hydroponically or in soil in a greenhouse. Plants were exposed to NaCl treatments (0, 100, and 200 mM) for 35 days, followed by 30 to 34 days of relief from salt stress to determine whether previously demonstrated genotypic differences in tolerance to salinity were related to water relations parameters. Exposure to high salt concentrations resulted in reductions in predawn water potential (Psi(w)), osmotic potential at full turgor (Psi(piFT)), osmotic potential at turgor loss point (Psi(piTLP)), and relative water content (RWC) in both cultivars, regardless of the growth substrate. Leaf Psi(w) and RWC returned to values similar to those of controls by the end of the relief period. The effect of salinity on Psi(pi) appeared earlier in Leccino than in Frantoio. Values for Psi(piFT) were -2.50, -2.87, and -3.16 MPa for the 0, 100, and 200 mM salt-treated Frantoio plants, respectively, and -2.23, -2.87, and -3.37 MPa for the corresponding Leccino plants. Recovery of Psi(pi) was complete for plants in the 100 mM salt treatment, but not for plants in the 200 mM salt treatment, which maintained an increased pressure potential (Psi(pi)) compared to control plants. Net solute accumulation was higher in Leccino, the salt-sensitive cultivar, than in Frantoio. In controls of both cultivars, cations contributed 39.9 to 42.0% of the total Psi(piFT), mannitol and glucose contributed 27.1 to 30.8%, and other soluble carbohydrates contributed 3.1 to 3.6%. The osmotic contribution of Na(+) increased from 0.1-2.1% for non-treated plants to 8.6-15.5% and 15.6-20.0% for the 100 mM and 200 mM salt-treated plants, respectively. The mannitol contribution to Psi(piFT) reached a maximum of 9.1% at the end of the salinization period. We conclude that differences between the two cultivars in leaf water relations reflect differences in the exclusion capacities for Na(+) and Cl(-) ions.

“…Salinity, mainly that created by inclusion of NaCl in the nutrient solution, has been shown to affect growth, nutrient composition, photosynthetic parameters and water relations of olive plants (Therios and Karagiannidis, 1991;Tattini et al, 1994Tattini et al, , 1995Tattini et al, , 1997Bartolini et al, 1991;Benlloch et al, 1991Benlloch et al, , 1994Klein et al, 1994;Heimler et al, 1995;Gucci et al, 1997;Chartzoulakis et al, 1999;Loupasaki et al, 1999;Vigo et al, 2002). Sharaf and Hobson (1986) showed that in tomato plants seawater had in general a similar effect to that of pure NaCl solutions, except that less Na was taken up by the plants.…”

The effects of six seawater dilutions (0%, 4.3%, 8.5%, 12.8%, 17.1%, and 21.3% seawater) on shoot growth, leaf development, nutrient concentration and distribution, and leaf anatomy of young olive plants of three cultivars ("Chondrolia Chalkidikis," "Manzanilla de Sevilla," and "Kalamon") were studied under greenhouse conditions. Olive plants showed a high tolerance up to 21.3% seawater. In general, the effects of seawater were: a reduction in growth, an increase in sodium (Na) and chloride (Cl) concentration, a decrease in potassium (K) and calcium (Ca) concentration, and a decrease in K/Na ratio of all plant parts. Furthermore, leaf boron (B) concentration was decreased. In contrast, magnesium (Mg) concentration increased in stems and roots. The plants retained Na and Cl ions in the basal part of stems and in roots, excluding them from leaves. Plants of "Chondrolia Chalkidikis" grown under 21.3% seawater developed leaves with a thicker palisade and spongy parenchyma, and with a hairier lower surface than the plants of the other two cultivars. "Kalamon" showed relatively high tolerance to salinity, followed by "Chondrolia Chalkidikis" and "Manzanilla de Sevilla." At all seawater dilutions, Na and Cl concentration of all plant parts was significantly lower in "Kalamon" than in the other two cultivars.

“…Additionally, ion stress is also caused by salt stress. Since excessive salt has severe effects on ion homeostasis and metabolic activity, some halophytes develop mechanisms to exclude or compartmentalize salt (Longstreth and Nobel 1979;Storey et al 1983;Heimler et al 1995). Thus, salt stress should be clearly distinguished from water stress.…”

Photosynthetic limitations of a halophyte sea aster (Aster tripolium L) under water stress and NaCl stress

To understand the mechanisms of salt tolerance in a halophyte, sea aster ( Aster tripolium L.), we studied the changes of water relation and the factors of photosynthetic limitation under water stress and 300 mM NaCl stress. The contents of Na + and Clwere highest in NaCl-stressed leaves. Leaf osmotic potentials ( Y s ) were decreased by both stress treatments, whereas leaf turgor pressure ( Y t ) was maintained under NaCl stress. Decrease in Y s without any loss of Y t accounted for osmotic adjustment using Na + and Claccumulated under NaCl stress. Stress treatments affected photosynthesis, and stomatal limitation was higher under water stress than under NaCl stress. Additionally, maximum CO 2 fixation rate and O 2 evolution rate decreased only under water stress, indicating irreversible damage to photosynthetic systems, mainly by dehydration. Water stress severely affected the water relation and photosynthetic capacity. On the other hand, turgid leaves under NaCl stress have dehydration tolerance due to maintenance of Y t and photosynthetic activity. These results show that sea aster might not suffer from tissue dehydration in highly salinized environments. We conclude that the adaptation of sea aster to salinity may be accomplished by osmotic adjustment using accumulated Na + and Cl -, and that this plant has typical halophyte characteristics, but not drought tolerance.
