Effects of natural clinoptilolite on physiology, water stress, sugar, and anthocyanin content in Sanforte (Vitis viniferaL.) young vineyard

Abstract

In the Mediterranea area, major effects of climate change are a modification in rainfall patterns, an increase in temperature with an intensify in tropical nights, and an increase in incoming radiations, especially UV-Bs. Despite the various adaptation strategies, grapevines are sensitive to altered climatic conditions. This paper aims to assess the benefits of applying a new sustainable product to the soil that can implement farmers’ resources to adapt to this changing situation. Zeowine was realized by combining the properties of zeolite, which has excellent potential in many sectors such as in agriculture, with the organic substance of a compost obtained on a company scale from the reuse of waste processing grapes, pomace and stalks. The effects of two different soil management (Z – Zeowine, 30 t/ha dose and C – Compost, 20 t/ha dose) on vine physiology and berry compositions in Sanforte grapevines (new plantation) were studied during the 2019–2020–2021 growing seasons in the San Miniato area, Italy. The following physiological parameters of grapevines were measured: leaf gas exchange, leaf temperature, stem water potential and chlorophyll fluorescence. The results showed that Z increased single leaf photosynthesis, reduced leaf temperature and water stress. In addition, phenolic and technological parameters were studied. The Z-treated vines had higher sugar content and total and extractable anthocyanin content as well as berry weight. These results suggested that the application of zeolites added to compost in the vineyard to the soil can be a valid tool to mitigate the effects of climate change.

Effect of Different Foliar Particle Films (Kaolin and Zeolitite) on Chemical and Sensory Properties of Olive Oil

“…CHA-zeolite is particularly attractive because of its very high CEC (3.84 meq/g) and easiness in sorption and release of NH 4 + [8,9]. Compared to kaolin, interest in the uses of zeolitites for agricultural purposes has raised in the last decade; zeolitites can be also potentially used (i) as carriers of nutrients to promote nutrient use efficiency [10] since the effect of microelement foliar application is known to influence the concentration of nutrients and chemical composition of olive fruits [11] and (ii) as pesticide carriers for controlling pests and diseases [12]. Furthermore, zeolitites are extensively used in agriculture, especially after their classification as "nontoxic" by the Inernational Agency for Research on Cancer (IARC) and as safe for human consumption by the FDA.…”

Leaf Eco-Physiological Profile and Berries Technological Traits on Potted Vitis vinifera L. cv Pinot Noir Subordinated to Zeolite Treatments under Drought Stress

“…The zeolite application (clinoptilolite 80%, granulometry 0.2-2.5 mm; Zeocel, DND Biotech srl, PI, Italy) took place on February 8, 2021, at a dose of 1.0 kg per pot [77,78].…”

“…With a refractometer (RF40-ND model, FLIR Extech, Munich, Germany), total sugars ( • Brix) were determined. Titratable acidity (TA; gL −1 tartaric acid) was measured on a 10 mL sample by manual glass burette, titrating with 0.1 M NaOH to a pH 7.0 endpoint using a portable pH meter (Hanna instrument, RI, USA) [78].…”

Physiological and Molecular Responses of Woody Plants Exposed to Future Atmospheric CO2 Levels under Abiotic Stresses

“…In this scenario, plant growth, phenological phases and development will be frequently challenged by climatic fluctuations, leading food security and food quality to be at risk in an increasing world population [ 10 , 11 , 12 ]. A range of studies over the years has been developed in an attempt to understand how plants will cope with elevated CO 2 (e[CO 2 ]), isolated or combined with other abiotic stresses, to identify new approaches to increase global sustainability and crop yield [ 13 , 14 , 15 , 16 , 17 , 18 ].…”
