Plant responses were examined using growth analysis, combined with measurements of gas exchange, chlorophyll fluorescence and photosynthetic pigment concentrations. In addition, tissue concentrations of aluminium, calcium, copper, iron, potassium, magnesium, sodium, phosphorus and silicon were determined. Although high salinity decreased growth, this effect was alleviated by treatment with Si. Improved growth was associated with higher net photosynthetic rate (A), and greater water-use efficiency (WUE). Enhanced A at high salinity could be explained by beneficial effects of Si on the photochemical apparatus, and on chlorophyll concentrations. Ameliorative effects of Si were correlated with reduced sodium uptake, which was unrelated to a reduction in the transpiration rate, since Si-supplemented plants had higher stomatal conductances (Gs). These plants also had higher tissue concentrations of essential nutrients, suggesting that Si had a positive effect on the mineral nutrient balance in salt-stressed plants.

Spartina maritima is a C4 halophyte that is an important pioneer and ecosystem engineer in salt marshes of the Atlantic coast of southern Europe. A glasshouse experiment investigated the combined effects on its growth and photosynthetic apparatus of approximately doubling CO2 concentration (from 380 to 700 μmol mol−1) at a range of salinity (0, 171 and 510 mM NaCl). We measured relative growth rates, gas exchange, chlorophyll fluorescence parameters, photosynthetic pigment concentrations, and total ash, Na+, K2+, Ca2+ and N concentrations. Elevated CO2 stimulated growth of S. maritima by c. 65% at all external salinities; this growth enhancement was associated with greater net photosynthetic rate (A) and improved leaf water relations. A increased despite a drop in stomatal conductance in response to 700 μmol mol−1 CO2. CO2 and salinity had a marked overall effect on the photochemical (PSII) apparatus and the synthesis of photosynthetic pigments. ΦPSII values at midday decreased significantly with external salinity in plants grown at 380 μmol mol−1 CO2; and Fv/Fm and ΦPSII values were higher at 700 μmol mol−1 CO2 in presence of NaCl. Plant nutrient concentrations declined under elevated CO2, which can be ascribed to the dilution effect caused by an increase in biomass. The results suggest that the productivity S. maritima and the ecosystem services it provides will increase in likely future climatic scenarios.", "publicationTitle": "Chemosphere", "publisher": "", "place": "", "date": "October 2010", "volume": "81", "issue": "6", "section": "", "partNumber": "", "partTitle": "", "pages": "725-731", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Chemosphere", "DOI": "10.1016/j.chemosphere.2010.07.047", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0045653510008295", "accessDate": "2016-06-30T17:07:07Z", "PMID": "", "PMCID": "", "ISSN": "0045-6535", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "CO2 enrichment", "type": 1 }, { "tag": "Chlorophyll fluorescence", "type": 1 }, { "tag": "Photosystem II", "type": 1 }, { "tag": "Relative growth rate", "type": 1 }, { "tag": "Salinity", "type": 1 }, { "tag": "Spartina maritima", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2016-06-30T17:07:07Z", "dateModified": "2016-06-30T17:07:07Z" } }, { "key": "AW94JPM8", "version": 7, "library": { "type": "group", "id": 253770, "name": "vegetation_morphological_properties", "links": { "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/253770/items/AW94JPM8", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties/items/AW94JPM8", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/253770/items/EFCAHKS3", "type": "application/json" } }, "meta": { "createdByUser": { "id": 139343, "username": "morrisep", "name": "Edward P.

Plants of this species growing in the polluted Odiel marshes (Huelva, Spain) showed high levels of catalase, ascorbate and guaiacol peroxidase activities and ascorbate concentration (reduced and oxidized ascorbate). In addition, we found significant oxidation of the ascorbate pool, since only 40% of ascorbate was reduced, and low levels of photosynthetic pigments, suggesting that an oxidative stress was impairing S. densiflora. Transplantation to an unpolluted substrate in the laboratory led to a gradual change in all tested parameters: antioxidative activities and total ascorbate concentration decreased while the percentage of reduced ascorbate and pigment concentrations increased; these data agreed with the hypothesis that oxidative stress conditions in S. densiflora habitat were due to a polluted substrate. After 28 days, the plants were transplanted for a second time to polluted conditions, equivalent to those in their habitats, and a rapid alteration of the antioxidative system was observed. In the first 24 h, catalase and guaiacol peroxidase activities and ascorbate concentration increased greatly and the percentage of reduced ascorbate fell drastically. Regardless of this fact, ascorbate peroxidase activity did not change until the end of the first week, while photosynthetic pigments declined at a constant rate during the whole culture period. Subsequently, we found that the antioxidative system improved its reductive capacity gradually and slowly – over weeks – but this reductive power was rapidly lost within days or even hours.

Different UV-B levels were obtained by covering plants with UV-B opaque (blocked 93–100% of ambient UV-B) and UV-B attenuating (near-ambient) filters (reduced 20–25% of UV-B). Unfiltered plants were exposed to natural irradiance. UV-B filters had significant effects on temperature and photosynthetic pigments (due to changes in PAR; 400–700 nm). The growth of Salicornia species was inhibited after 35 to 88 days of exposure to mean UV-B radiation dosages between 3.6 and 4.1 kJ m−2 day−1. The highest number of branches on the main shoot (S. bigelovii and S. gaudichaudiana) and longest total length of the branches (S. gaudichaudiana) were observed in the UV-B opaque treatment. Salicornia species responded to increasing levels of UV-B radiation by increasing the amount of UV-B absorbing pigments up to 330%. Chromatographic analyses of seedlings and adult S. bigelovii plants found seven different UV-B absorbing flavonoids that are likely to serve as UV-B filtering pigments.

Finally, the decline in the photosynthetic function resulted in a biomass reduction of between 50 and 80% (for 600 and 5000 mg Cu kg−1, respectively).", "publicationTitle": "Marine Environmental Research", "publisher": "", "place": "", "date": "October 2008", "volume": "66", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "459-465", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Marine Environmental Research", "DOI": "10.1016/j.marenvres.2008.07.007", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0141113608001943", "accessDate": "2016-06-30T16:24:23Z", "PMID": "", "PMCID": "", "ISSN": "0141-1136", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Copper", "type": 1 }, { "tag": "Growth rate", "type": 1 }, { "tag": "Invader", "type": 1 }, { "tag": "Photosynthesis", "type": 1 }, { "tag": "Photosynthetic pigments", "type": 1 }, { "tag": "Spartina densiflora", "type": 1 }, { "tag": "Tissue analysis", "type": 1 }, { "tag": "photochemistry", "type": 1 }, { "tag": "salt marshes", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2016-06-30T16:28:23Z", "dateModified": "2016-06-30T16:28:23Z" } }, { "key": "R9MRRVBS", "version": 7, "library": { "type": "group", "id": 253770, "name": "vegetation_morphological_properties", "links": { "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/253770/items/R9MRRVBS", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties/items/R9MRRVBS", "type": "text/html" } }, "meta": { "createdByUser": { "id": 139343, "username": "morrisep", "name": "Edward P.

A glasshouse experiment was designed to investigate the effect of Zn from 0 to 100 mmol·l−1 on the growth and photosynthetic apparatus of S. densiflora, by measuring relative growth rate, leaf elongation rate, number of tillers, height of tillers, chlorophyll fluorescence parameters, gas exchange and photosynthetic pigment concentrations. We also determined total ash, Zn, calcium, magnesium and phosphorus concentrations, and the C/N ratio. At 100 mmol·l−1 Zn, S. densiflora showed a 48% biomass reduction after 1 month of treatment. Long-term effects of Zn on growth of S. densiflora consisted mainly of variations in net photosynthesis. Modification of the Zn/Mg ratio was linked to a strong decrease in RuBP carboxylase (Zn was favoured in local competition with Mg, so that the affinity of RuBisCO for CO2 decreased), oxygenase activity of RuBisCO acting as a substitute for the photosynthetic function. Also, Zn had a marked overall effect on the photochemical (PSII) apparatus and the synthesis of photosynthetic pigments. However, the results indicate that S. densiflora is capable of tolerating very high and continued exposure to Zn, as this species lowers the translocation of Zn from the nutrient solution to roots and controls Zn ion transport into leaves.

It is virtually confined to coastal salt marshes, where it often dominates the vegetation. The aim of this study was to investigate its growth responses to salinity and the extent to which these could be explained by photosynthetic physiology.\nMethods The responses of young plants to salinity in the range 0–700 mol m−3 NaCl were investigated in a glasshouse experiment. The performance of plants was examined using classical growth analysis, measurements of gas exchange (infrared gas analysis), determination of chlorophyll fluorescence characteristics (modulated fluorimeter) and photosynthetic pigment concentrations; total ash, sodium, potassium and nitrogen concentrations, and relative water content were also determined.\nKey Results Plants accumulated Na+ approximately in proportion to external salinity. Salt stimulated growth up to an external concentration of 200 mol m−3 NaCl and some growth was maintained at higher salinities. The main determinant of growth response to salinity was unit leaf rate. This was itself reflected in rates of CO2 assimilation, which were not affected by 200 mol m−3 but were reduced at higher salinities. Reductions in net photosynthetic rate could be accounted for largely by lower stomatal conductance and intercellular CO2 concentration. Apart from possible effects of osmotic shock at the beginning of the experiment, salinity did not have any adverse effect on photosystem II (PSII). Neither the quantum efficiency of PSII (ΦPSII) nor the chlorophyll fluorescence ratio (Fv/Fm) were reduced by salinity, and lower mid-day values recovered by dawn. Mid-day Fv/Fm was in fact depressed more at low external sodium concentration, by the end of the experiment.\nConclusions The growth responses of the hygro-halophyte A. portulacoides to salinity appear largely to depend on changes in its rate of photosynthetic gas exchange. Photosynthesis appears to be limited mainly through stomatal conductance and hence intercellular CO2 concentration, rather than by effects on PSII; moderate salinity might stimulate carboxylation capacity. This is in contrast to more extreme halophytes, for which an ability to maintain leaf area can partially offset declining rates of carbon assimilation at high salinity.", "publicationTitle": "Annals of Botany", "publisher": "", "place": "", "date": "09/01/2007", "volume": "100", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "555-563", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Ann Bot", "DOI": "10.1093/aob/mcm119", "citationKey": "", "url": "http://aob.oxfordjournals.org/content/100/3/555", "accessDate": "2016-06-30T16:16:57Z", "PMID": "", "PMCID": "", "ISSN": "0305-7364, 1095-8290", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "aob.oxfordjournals.org", "callNumber": "", "rights": "", "extra": "PMID: 17684026", "tags": [ { "tag": "Atriplex portulacoides", "type": 1 }, { "tag": "Chlorophyll fluorescence", "type": 1 }, { "tag": "Growth rate", "type": 1 }, { "tag": "Photosynthesis", "type": 1 }, { "tag": "Photosystem II", "type": 1 }, { "tag": "halophyte", "type": 1 }, { "tag": "leaf area", "type": 1 }, { "tag": "salt marsh", "type": 1 }, { "tag": "salt tolerance", "type": 1 }, { "tag": "stomatal conductance", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2016-06-30T16:17:25Z", "dateModified": "2016-06-30T16:17:25Z" } }, { "key": "6XC7XDKR", "version": 7, "library": { "type": "group", "id": 253770, "name": "vegetation_morphological_properties", "links": { "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/253770/items/6XC7XDKR", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/vegetation_morphological_properties/items/6XC7XDKR", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/253770/items/8ZV72ZWI", "type": "application/json" } }, "meta": { "createdByUser": { "id": 139343, "username": "morrisep", "name": "Edward P.
