“…Proline, one of crucial osmoprotectants under adversity conditions, plays a key role in scavenging reactive oxygen species and facilitating water uptake (Ruiz-Sánchez et al, 2010). DS treatment resulted in an increased change in root proline concentrations, regardless of AM and non-AM plants (Fig.…”

White clover is extremely susceptive to drought stress (DS), while it is not clear whether arbuscular mycorrhizal fungi (AMF) enhance drought tolerance of the plant. This study was carried out to evaluate effects of two AMF species, Funneliformis mosseae and Paraglomus occultum, on flavonoid, soluble protein, proline, and nutrient uptake in roots of white clover under well-watered (WW) and DS conditions. Root colonization by F. mosseae and P. occultum was heavily decreased by 7-week DS treatment. Mycorrhizal plants showed considerably greater biomass production in shoot, root, and total (shoot+root) than non-mycorrhizal plants, irrespective of soil water status. AMF inoculation led to significantly higher root soluble protein and proline accumulation under WW and DS and root flavonoid level under DS, regardless of AMF species. Root N, P, K and Cu concentrations were dramatically increased by mycorrhization under WW and DS, and root Ca, Mg, Fe, and Mn levels were significantly higher in AMF plants than in non-AMF plants under WW. It concluded that AMF strongly enhanced plant growth and drought tolerance of white clover by greater nutrient absorption and protective substances (soluble protein, proline, and flavonoid) accumulation.

“…Proline accumulation in plants without mycorrhizae was higher than plants with mycorrhizae during water stress (Vazquez et al, 2001;Sanchez et al, 2010;Wu & Xia, 2006). Hapsoh et al (2006), elevated levels of proline in plants as an osmotic regulator that involves the accumulation of soluble compounds.…”

The objective of this experiment was to evaluate the effect of drought stress and mycorrhizal inoculation on physiological adaptation and biomass production of Macroptilium bracteatum. This experiment was arranged in completely randomized design with four treatments: M0 (no AM + watered), M1 (AM + watered), M2 (no AM + drought), and M3 (AM + drought) with three replicates. The observed variables were soil water content, leaf water potential, leaf relative water content, leaf proline, leaf water soluble carbohydrate (WSC), root and shoot dry weight. Data were analyzed by ANOVA and differences between treatments were tested by DMRT. Drought treatments (M2 and M3) significantly (P<0.05) decrease soil water content, leaf water potential, leaf relative water content and increased the leaf proline content. The result in root and shoot dry weight appear that M1 treatment was significantly different (P<0.05) with treatment M0, M2, and M3. For leaf WSC, M0 and M2 treatments were significantly different (P<0.05) with treatment M1 and M3. It is concluded that mycorrhiza inoculation was more effective on M. bracteatum, in drought stress. One mechanism of drought resistance of M. bracteatum is the accumulation of osmotic compounds proline. Therefore, proline can be used as an indicator of drought resistance in leguminous plants.

“…Soil water scarcity can have negative impacts on plant growth and grape production, whereas irrigation practice can alleviate water-stress-related reductions in plant development, demonstrating the importance of cultural practice at the vineyard to guarantee grape quality, especially in semiarid areas (Teixtera et al, 2013). Nevertheless, full irrigation is not recommended in vineyards since it increases berry size with a consequent decrease of the skin/pulp ratio, which negatively affects grape quality (Ruiz-Sanchez et al, 2010). The Montepulciano red variety is widespread in central Italy and particularly in the northern part of Latium region, where the volcanic environment is characterized by soil with low content of organic matter and moderate available water capacity.…”

Montepulciano red grape is cultivated in the northern part of the Latium region, primarily for the production of DOC "Colli Etruschi Viterbesi" structured wines for aging. In Mediterranean areas, viticulture is closely influenced by vine water status. In this context, the practice of irrigation may alleviate water-stress-related reductions in plant development to guarantee grape quality, especially in semi-arid areas. The application of on-farm compost in a vineyard may affect grape quality without negative effects, thereby enhancing environmental sustainability. The aim of this work was to investigate the combined effect of irrigation and compost application on the Montepulciano variety in the volcanic environment of Latium region, thereby improving the polyphenol concentrations in the berries. The trial was conducted during three growing seasons (2011)(2012)(2013). Irrigation was performed according to the protocol proposed by Ojeda and Saurin (2014). The pre-dawn leaf water potential (ψpd) from July to September was measured weekly for maintaining vine water status in the range between -0.4 and -0.6 Mpa. Irrigation (I) and irrigation plus compost application (IC) were compared to a non-irrigated control (C). Berry weight was not influenced by moderate irrigation, whereas titratable acidity and total soluble solids were negatively correlated to the increment of water dropped. The primary finding was a positive influence on polyphenol contents of the grapes at harvest. Best performance was highlighted in 2012 with 263 liter vine -1 of water supplied. Overall, the sustainable use of water and on-farm compost improved Montepulciano grape quality in this volcanic area, thereby enhancing the adaptation of Mediterranean viticulture to climate change conditions.
