    Steady state osmotic adaptation inUlva lactuca (1980)
    Springer
    Planta 150 (1980), S. 158-165 
    Details
    ISSN: 1432-2048
    Keywords: β-Dimethylsulphoniopropionate ; Osmoregulation ; Ion relations ; Salinity ; Ulva
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The effects of hyper- and hypo-saline stresses on the levels of various inorganic and organic solutes inUlva lactuca have been recorded. Hypoosmotic stress decreased the tissue concentration of K+, Na+ and Cl- while hyper-osmotic stress caused a transient increase in Na+ and a stable accumulation of K+ and Cl-. The tissue content of β-dimethylsulphoniopropionate (β-dimethylpropiothetin) responded to changes in salinity. The time course of hypersaline stress showed the β-dimethylsulophoniopropionate concentration rose as the Na+ level fell. The levels of free sugars and amino acids, including proline, were relatively low in this alga and did not appear to be important in osmotic adjustment. The possibility that tertiary sulphonium dipolar ions have an analogous role in some algae to glycinebetaine and possibly other quaternary nitrogen compounds in higher plants as cytoplasmic osmotica is discussed briefly.

    The validity of the lead precipitation technique for the localization of ATPase activity in plant cells (1980)
    Springer
    Protoplasma 104 (1980), S. 193-200 
    Details
    ISSN: 1615-6102
    Keywords: Analytical electron microscopy ; ATPase cytochemistry ; Plasma membrane ; Ricinus communis ; Triticum aestivum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The claim that osmium-containing deposits which lack lead are frequently and incorrectly interpreted as enzymatic reaction products in lead precipitation techniques for ATPase localization in plants is without foundation. Proper controls clearly demonstrate the enzymatic origin of membrane-located deposits and the presence of lead is confirmed by analytical electron microscopy.

    Rhizosphere salinity and phytoalexin accumulation in soybean (1980)
    Springer
    Plant and soil 54 (1980), S. 163-167 
    Details
    ISSN: 1573-5036
    Keywords: Phytoalexin ; Phytophthora megasperma ; Salinity ; Soybean ; Rhizosphere
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Rhizosphere salinity decreased the capacity of soybean to accumulate a pterocarpanoid phytoalexin (glyceollin) in the stem in response toPhytophthora megasperma var.sojae. Rapid (48h) accumulation was depressed by NaCl, Na2SO4, CaCl2 and MgSO4 applications. Time-course accumulations was slowed by applications. Time-course accumulation was slowed by application of 0.131M NaCl. Glyceollin accumulation was also reduced in plants subjected to a period of high salinity stress (0.177M NaCl, 72 h) after a period of nonsalinized growth. Calcium chloride completely suppressed glyceollin accumulation in normally-resistant plants but no susceptibility to the fungus was observed.

    Growth of ornamental plants irrigated with nutrient or polyethylene glycol solutions of different osmotic potentials (1980)
    Springer
    Plant and soil 56 (1980), S. 99-111 
    Details
    ISSN: 1573-5036
    Keywords: Aster ; Bedding plants ; Celosia ; Coleus ; Growth effects ; Marigold ; NPK solutions ; Osmotic stress ; Petunia ; Polyethylene glycol ; Salinity ; Snapdragon
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Six ornamental species (Petunia hybrida, Callistephus hortensis, Coleus blumei, Celosia pyramidalis, Antirrhinum majus andTagetes erecta) were grown in solutions containing high concentrations of polyethylene glycol (MW 4000) or of Nitrogen: Phosphorus: Potassium. At equal osmotic potentials, top dry weight, leaf area and leaf elongation rate were all reduced more by polyethylene glycol than by NPK. Polyethylene glycol also produced some leaf damage which did not occur with NPK solutions. Osmotic potentials of −600 kPa due to NPK reduced growth of the six species by at least 25% compared with growth of control plants (at −20 kPa). Tolerance ranking to high fertilizer in the irrigation solution increased from Snapdragon (most sensitive), Marigold Coleus, Aster, Celosia and Petunia (most tolerant).

    Influence of salinity on mineral nutrition of peanut (Arachis hypogea L.) (1980)
    Springer
    Plant and soil 54 (1980), S. 5-13 
    Details
    ISSN: 1573-5036
    Keywords: Arachis hypogea ; Mineral nutrition ; Peanut ; Salinity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Effect of sodium chloride and sodium sulphate salinities on growth and mineral nutrition of peanut (A. hypogea L.) variety TMV-10 has been studied. Both salts suppressed growth of the plants. The inorganic analysis revealed that NaCl and Na2SO4 caused accumulation of Na, P, Fe and Mn in root, stem, leaf and gynophore. NaCl treatment caused accumulation of Cl in these parts. The uptake of K was hampered by both salts whereas Ca uptake was retarded mainly by Na2SO4. The results are discussed in relation to the salt tolerance capacity of the plant.

    The effect of temperature on salt uptake by tomato plants with diurnal and noctural waterlogging of salinized rootzones (1980)
    Springer
    Plant and soil 56 (1980), S. 113-121 
    Details
    ISSN: 1573-5036
    Keywords: Drainage ; Lycopersicon esculentum ; Salinity ; Temperature ; Tomato
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Tomato plants were grown at three constant temperatures (10, 20 and 28°C) with drained or waterlogged rootzones and were irrigated with saline solution (0.09M NaCl). Each increase in temperature resulted in an increase in leaf Na-ion and Cl-ion concentrations in plants grown with drained rootzones. However, with plants grown with waterlogged rootzones, maximum leaf concentrations of Na-ions and Cl-ions occurred at 20°C. At 10°C there were no differences between Na-ion and Cl-ion concentrations for drained or waterlogged treatments. At 20 and 28°C, waterlogging of the rootzone resulted in significantly higher concentrations of Na-ions and Cl-ions in leaf and stem tissues than occurred with drained rootzones. There were no differences in Na-ions and Cl-ions and Cl-ions in plant tops if plants were waterlogged with saline solution during the day or night. Transpiration increased significantly with each increase in temperature but showed no other treatment dependent responses.
