“…The primary action of Ca 2 § on ion absorption is to change the permeability of the root membranes, whereby Na § absorption was diminished (Leopold and Willing, 1984). Calcium was found to have a secondary role on ion translocation within the plant, a characteristic that has even been found in spruce trees under salt-stress (Bogemans et al, 1989). This secondary role of calcium is clearly observed in our field experiment, where a remarkable difference between Na § and C1-concentrations in needles and twigs was found between the trees of the CaCO 3 enriched soil for the 75/25 NaC1/CaC12 and for the 100% NaCI treatments.…”

“…Another possibility lies within the field of the salt mixtures. From earlier experiments it was found that through the pattern of ion distribution, mixtures of NaCI/CaC12 were very promising in reducing salt injury (Bogemans et al, 1989). Growth under NaCl-stress of barley plants is enhanced by an increase of Ca 2 +-concentration (Kawasaki and Moritsugu, 1978).…”

Effect of deicing NaCl and CaCl2 on spruce (Picea abies (L.) sp.)

NaCI and CaC12 are frequently used as deicing agents during the winter season. The present study compares the effect of these deicing salts on salt injury on spruce trees (Picea abies sp.). From two field experiments carried out for ten weeks during the winter period of 1986-1987, and a total dose of 1.5 kg m -2 NaC1, CaC12 or a 75/25 NaC1/CaC12 mixture, it was found that the presence of calcium clearly reduced the salt injury as was indicated by salt tolerance ratings. These ratings corresponded well to the CI concentrations found in needles and twigs. Though an equal dose of C1-was given, in the presence of CaCI2 the uptake of C1-was inhibited. Surely the role of calcium on ion permeability in salinized soil should have its effect, together with the regulatory role that calcium has on ion accumulation and transport. Furthermore it was found that the climatic conditions and the calcium status of the soil only have an effect on the time of appearance of the injury.

“…Nevertheless, in (relatively) salt-resistant genotypes of some crop species, Na + compartmentalisation in leaf vacuoles may also contribute to salinity tolerance [59]. Salinity caused the accumulation of high concentrations of Na + and Cl − in L. decidua roots and needles, as reported for other coniferous species [27,60,61]. When comparing ion levels between roots and needles, no differences were observed in Na + contents (in terms of DW), neither in control nor in salt-stressed seedlings; regarding Cl − , its concentration was slightly (but significantly) higher in needles than in roots, again in both non-stressed and salt-stressed seedlings.…”

Larix decidua, the European larch, is not normally affected by drought or salinity in its natural habitats, but it may be when grown as an ornamental tree, by the widespread practice of winter de-icing of mountain roads with NaCl, and because of global warming-induced environmental changes. The responses of two-month-old larch seedlings to 30 days water deficit (withholding irrigation) or salt stress (150 mM NaCl) treatments were studied by determining stress-induced changes in several growth parameters and biochemical markers (ion and osmolyte contents, level of oxidative stress, activation of enzymatic and non-enzymatic antioxidant systems). Both treatments caused the inhibition of growth, degradation of photosynthetic pigments, a small increase in malondialdehyde (MDA, an oxidative stress biomarker), and the activation of antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR). In all cases, salinity appeared to have stronger effects on the seedlings than water deficit. The presence of relatively high concentrations of glycine betaine, both in control and stressed plants, may represent a constitutive mechanism of defence against stress in European larch. Additionally, other responses were specific for salt stress and included the activation of K + transport from roots to shoots and the accumulation of Pro as an osmoprotectant.

“…Chloride concentrations as low as 250 mg/L are recognized as harmful to freshwater life (Office of Water, Regulations, and Standards, Criteria and Standards Division 1988), and chronic inputs of Cl are thought to negatively affect plants of wetlands and uplands (Bogemans et al 1989;Richburg et al 2001). Moreover, maintenance of high concentrations during the more biologically active summer months may increase ecological effects.…”

Several recent reports document increasing concentrations of chloride in surface waters of northeastern and midwestern North America. These patterns, together with high summertime baseflow concentrations, suggest the possibility of short-term retention of winter-applied chloride within catchments. This study examined the potential of groundwater and soils to act as reservoirs of Cl within the watershed of a small rural stream in New York that has shown a doubling of Cl over the past two decades and almost constant concentrations across seasons. Groundwater samples were obtained from 20 private drinking wells distributed around the catchment to determine whether concentrations were at or greater than surface waters and so could act as a source to the stream. In 16 of the 20 wells, chloride concentrations were lower (mean of 16 samples=4.10 mg Cl/L (standard deviation=4.8)) than concurrent streamwater concentrations (mean of eight locations sampled on two dates=28.9 (5.8)). Four wells, however, showed higher concentrations ranging from 35 to 230 mg Cl/L suggesting either point source contamination or very heterogeneous groundwater chloride sources. Soil cores from the catchment were irrigated in the laboratory with a NaCl solution for 2 weeks followed by 2 weeks irrigation with a chloride-free solution. Chloride concentrations in core leachates were lower than in the irrigation solution during the first 2 weeks indicating some retention of Cl within the cores. After cores were irrigated with chloride-free water, leachate concentrations declined but would not reach streamwater concentrations until the equivalent of 15 cm of precipitation was added to the core.
