“…Limited water supply has been shown to promote fructose accumulation in Arabidopsis thaliana, 7 Withania somnifera, 8 and strawberry. 26 On the other hand, no differences were observed in fructose content in four strawberry cultivars submitted to water deficit, 27 indicating that the effect of these stresses on the content of soluble sugars might be stress and / or dose-dependent as well as species or cultivar specific. Sugar accumulation seems to improve fruit tolerance to abiotic stresses, keeping cell turgor, as well as membrane protection, and scavenging free radicals.…”

BACKGROUND Plants activate defense mechanisms to cope with adverse environmental conditions, leading to the accumulation and / or depletion of general and specialized metabolites. In this study, a multiplatform untargeted metabolomics strategy was employed to evaluate metabolic changes in strawberry fruit of cv. Camarosa grown under osmotic stress conditions. Liquid chromatography‐mass spectrometry (LC‐MS/MS) and gas chromatography‐mass spectrometry (GC‐MS) data from strawberries grown under two water‐deficit conditions, irrigated at 95% crop evapotranspiration (ETc) and 85% ETc, and one excess salt condition with a 80 mmol L−1 NaCl solution, were analyzed to determine treatment effects on fruit metabolism. RESULTS Multivariate principal component analysis, orthogonal projections to latent structures – discriminant analysis (OPLS‐DA), and univariate statistical analyses were applied to the data set. While multivariate analyses showed group separation by treatment, T‐tests and fold change revealed 12 metabolites differentially accumulated in strawberries from different treatments – among them phenolic compounds, glycerophospholipids, phytosterols, carbohydrates, and an aromatic amino acid. CONCLUSION Untargeted metabolomic analysis allowed for the annotation of compounds differentially accumulated in strawberry fruit from plants grown under osmotic stress and non‐stressed plants. The metabolic disturbance in plants under stress involved metabolites associated with the inhibition of reactive oxygen species and cell‐wall and membrane lipid biosynthesis, which might serve as osmotic stress biomarkers. © 2019 Society of Chemical Industry

“…Strawberry consumes a great amount of water because of its large leaf area, shallow root system and juicy texture. Consequently, it vegetative and reproductive growth are significantly damaged under drought stress, thereby reducing its biomass and crop yield 15 . The negative influences of osmotic stress are alleviated by ion exclusion, accumulation of soluble compounds such as proline and carbohydrates, and control of ion increase in roots through their transport to leaves 5 .…”

Drought is an important environmental stress that has negative effects on plant growth leading to a reduction in yield. In this study, the positive role of nanoparticles of SiO2, Se, and Se/SiO2 (SiO2-NPs, Se-NPs and Se/SiO2-NPs) has been investigated in modulating negative effects of drought on the growth and yield of strawberry plants. Spraying of solutions containing nanoparticles of SiO2, Se, and Se/SiO2 (50 and 100 mg L−1) improved the growth and yield parameters of strawberry plants grown under normal and drought stress conditions (30, 60, and 100%FC). Plants treated with Se/SiO2 (100 mg L−1) preserved more of their photosynthetic pigments compared with other treated plants and presented higher levels of key osmolytes such as carbohydrate and proline. This treatment also increased relative water content (RWC), membrane stability index (MSI) and water use efficiency (WUE). In addition, exogenous spraying of Se/SiO2 increased drought tolerance through increasing the activity of antioxidant enzymes including catalase (CAT), ascorbate peroxidase (APX), guaiacol peroxidase (GPX) and superoxide dismutase (SOD) as well as decreasing lipid peroxidation and hydrogen peroxide (H2O2) content. Increase in biochemical parameters of fruits such as anthocyanin, total phenolic compounds (TPC), vitamin C and antioxidant activity (DPPH) in strawberry plants treated with Se/SiO2 under drought stress revealed the positive effects of these nanoparticles in improving fruit quality and nutritional value. In general, our results supported the positive effect of the application of selenium and silicon nanoparticles, especially the absolute role of Se/SiO2 (100 mg L−1), on the management of harmful effects of soil drought stress not only in strawberry plants, but also in other agricultural crops.

“…Mainly drought stress causes to decrease yield and quality and affects biochemical features in arid or semi-arid climate, for example Mediterrenean conditions (Souza et al, 2004;Zlatev and Lidon, 2012;Adak et al, 2018b;Tunc et al, 2019). Adak et al (2018b) stated that some of the fruit's physical features were affected negatively by stress conditions whereas many of the biochemical features such as total anthocyanin content, total phenolic content and antioxidant activity were positively modulated in strawberries. Barreales et al (2019) stated that deficit irrigation applications drastically affect the phytochemical composition and antioxidant activity of grapevine leaves.…”

Glycine betaine (GB) is a quaternary ammonium compound that can be found in a wide range of bacterial, plant and animal species. The exogenous application of GB is a convenient method for the induction of crop tolerance to various abiotic stresses. We examined the effects of different exogenous GB concentrations to deficit irrigation conditions (15% drainage) under soilless condition in terms of morpho-physiological, yield, quality and biochemical features. The different GB concentrations (0, 10 and 20 mM) were used in Fortuna and Albion strawberry cultivars. As a result of the research, GB treatments increased plant growth and yield under deficit irrigation conditions. Fruit weight inclined by 26.29-49.50% and fruit yield by 17.17-39.59% at GB treatments as compared to control. Regarding biochemical content, increasing GB concentrations from 0 mM to 20 mM caused total anthocyanin to decrease, whereas the ascorbic acid increased. Furthermore, the highest yield, fruit firmness, chroma and total anthocyanin were determined in the Fortuna; the highest total soluble solid and ascorbic acid content in the Albion cultivar. Our results showed that the increase in yield and quality was due to exogenous GB applications. Indeed, water stress tolerance varied depending on cultivars.
