Kaolin particle film application lowers oxidative damage and DNA methylation on grapevine (Vitis vinifera L.

Potential role of kaolin or potassium sulfate as anti-transpirant on improving physiological, biochemical aspects and yield of wheat plants under different watering regimes

“…POX and CAT convert H 2 O 2 into water and molecular oxygen, which are harmless to plants (Moller et al 2007). These results were in good harmony with the results obtained by Bernardo et al (2017). Kaolin particle film could induce SOD and CAT activities under stress.…”

Grapevine abiotic stress assessment and search for sustainable adaptation strategies in Mediterranean-like climates. A review

“…Phenolic accumulation is also linked with several environmental disturbances (Ferrandino and Lovisolo 2014). Indeed, under high temperatures exposure, the probably increased degradation and inhibition of anthocyanins synthesis may lead to higher H 2 O 2 production with forwarding induction of the antioxidant machinery (Mori et al 2015;Conde et al 2016;Bernardo et al 2017). Flavonoids act as primary antioxidants in plant responses to a wide range of stresses, inhibiting ROS production and reducing ROS levels once they are formed (Agati et al 2012).…”

“…Many authors have focused their research on the development of environmentally friendly practices, like kaolin application, to sustain yield and quality in a challenging climate, through the reduction of leaf and fruit berry surface temperature, thus improving the antioxidant machinery (Glenn 2012;Boari et al 2015;Dinis et al 2015). In fact, foliar application of solar protectants, has already shown promising results regarding grapevine increased yield, physiological performance, and general fruit quality potential, in the context of climate change at a local scale (Coniberti et al 2013;Dinis et al 2016;Bernardo et al 2017;Dinis et al 2017;Conde et al 2018;Dinis et al 2018). Nitrogen composition in must also plays an important role on grape and wine quality potential, affecting yeast metabolism, fermentation kinetics, the amino acid content, and synthesis of volatile fermentative compounds, since the amino acids are precursors of volatile compounds (Bell and Henschke 2005;Arias-Gil et al 2007).…”

EFFECTS OF KAOLIN AND DICARBOXYLIC ACID BASED STRESS INHIBITORS ON AROMA COMPOSITION OF TWO TABLE GRAPE CULTIVARS (V. vinifera L.)

“…in viticulture are still limited. In few studies conducted in this area, it has been reported that particle films can contribute to improve berry composition and wine quality in arid regions [Brillante et al 2016, Dinis et al 2016and Bernardo et al 2017.…”
