“…Scanning electron microscope (SEM) images were captured and used to examine differences in wax morphology. Preparation of leaf samples followed the method reported by Åström et al [27]. The youngest fully developed leaf after the end of fruit production was harvested.…”

“…The samples were fixed individually in FAA (formalin acetic acid-alcohol) solution (36% paraformaldehyde, 100% acetic acid, 85% ethanol; 10:5:85 by volume) for a minimum of 3 weeks. After fixation, the samples were dehydrated through an ethanol series (25%, 50%, 75%, and 100%) [27]. 5-8 mm completely dried pieces of prepared leaf samples, were attached with double adhesive tape to the aluminum stubs and sputter-coated with gold particles.…”

Application of Nano-Silicon Dioxide Improves Salt Stress Tolerance in Strawberry Plants

Silicon application can improve productivity outcomes for salt stressed plants. Here, we describe how strawberry plants respond to treatments including various combinations of salt stress and nano-silicon dioxide, and assess whether nano-silicon dioxide improves strawberry plant tolerance to salt stress. Strawberry plants were treated with salt (0, 25 or 50 mM NaCl), and the nano-silicon dioxide treatments were applied to the strawberry plants before (0, 50 and 100 mg L−1) or after (0 and 50 mg L−1) flowering. The salt stress treatments reduced plant biomass, chlorophyll content, and leaf relative water content (RWC) as expected. Relative to control (no NaCl) plants the salt treated plants had 10% lower membrane stability index (MSI), 81% greater proline content, and 54% greater cuticular transpiration; as well as increased canopy temperature and changes in the structure of the epicuticular wax layer. The plants treated with nano-silicon dioxide were better able to maintain epicuticular wax structure, chlorophyll content, and carotenoid content and accumulated less proline relative to plants treated only with salt and no nano-silicon dioxide. Analysis of scanning electron microscopic (SEM) images revealed that the salt treatments resulted in changes in epicuticular wax type and thickness, and that the application of nano-silicon dioxide suppressed the adverse effects of salinity on the epicuticular wax layer. Nano-silicon dioxide treated salt stressed plants had increased irregular (smoother) crystal wax deposits in their epicuticular layer. Together these observations indicate that application of nano-silicon dioxide can limit the adverse anatomical and biochemical changes related to salt stress impacts on strawberry plants and that this is, in part, associated with epicuticular wax deposition.

“…The absence of an effect on the dry weight of I. montana here illustrates the strong variability of this xerophilous plant, namely its capacity to grow in various habitats and its ability to resist drought. Chlorophyll a fluorescence has been described as an accurate indicator of the plant response to environmental fluctuations and biotic stress (Murchie and Lawson, 2013;Guidi and Calatayud, 2014) and has gained interest in ecophysiological studies (Åström et al, 2015;Perera-Castro et al, 2017). The maximum photochemical quantum yield of PSII (Fv/Fm) and the performance index (PI) reflect photooxidative stress and plant fitness (Strasser et al, 2000).…”

“…During the winter, the metabolic rates of plants are reduced by the cold. Some plants, such as Fragaria vesca L. and Vaccinium vitis‐idaea L. continue physiological processes and development under snow, however (Åström, Metsovuori, Saarinen, Lundell, & Hänninen, ; Crawford, ; Halfpenny & Ozanne, ; Lundell, Saarinen, Aström, & Hänninen, ). Our study confirmed that Sphagnum mosses have the ability for year‐around growth.…”

Sphagnum is the major genus in northern peatlands that contributes to peat formation and carbon sequestration. Sphagnum growth in summer has been fairly well studied but the information about growth in autumn and winter is limited. Therefore, we studied how the growth of Sphagnum is seasonally distributed with a particular interest on possible winter growth. The linear increment and biomass production of three Sphagum species was measured in three Northern European bogs over a year. In all sites, our results indicate the highest annual linear increment in S. angustifolium (28 mm), followed by S. magellanicum (20 mm) and S. fuscum (13 mm), but the biomass production was fairly even among the species (189, 192 and 215 g m −2 , respectively). Both linear increment and biomass production depended mostly on meteorological parameters rather than ecophysiological or microsite properties. The seasonal measurements revealed a significant linear increment and biomass production during the winter that accounted for ca. 10% and ca. 5% from the annual values, respectively.Moreover, the mean daily rates of linear increment in autumn often exceeded the increment in summer. Our results thus indicate the ability for year-around growth of Sphagna if the conditions are favorable, including during boreal winter.
