Abstract:

Grapevine physiology is influenced by several environmental factors, such as temperature, precipitation, potential evapotranspiration, and sunshine hours. Due to climatic changes, effects in grapevine physiology and consequently on the grape berry composition and quality have been observed. This work aims to make a comparative study of the effect of foliar mitigation treatment with kaolin (5%) and potassium silicates (0.1% and 0.05%) on the grape berry quality; namely on berry weight, pH, probable alcohol, total phenolics, tannins, total anthocyanins, monomeric anthocyanins, calcium, potassium

Abstract:

Background and aims: In most viticultural areas of the world, Vitis vinifera grapevines require grafting onto phylloxera-tolerant rootstocks of American origin. The species most commonly used in rootstock creation are Vitis berlandieri, V. riparia and V. rupestris. Rootstocks not only provide tolerance to phylloxera but also ensure the supply of water and mineral nutrients to the scion. The aim of the study was to investigate the extent to which rootstocks with different genetic backgrounds modify the mineral composition of the petioles of the scion.Methods and results: Vitis vinifera cv.

Abstract:

Biochar has attracted interest in viticulture for its potential to enhance nutrient uptake and improve grapevine physiology under changing climatic conditions, particularly in Mediterranean regions. However, the widespread adoption of biochar has been limited due to economic and logistical constraints associated with its large-scale application. To address these barriers hindering the widespread adoption of biochar, this study investigates the effects of foliar-applied water suspensions of biochar at concentrations of 300 mg/L (B300), 600 mg/L (B600), and 1200 mg/L (B1200), compared to a water

Background: Grapevine (Vitis vinifera L.) is a globally important perennial fruit crop, renowned for its economic value and cultural significance. Grape leaves, while often underappreciated, play a vital role in culinary traditions and are valued for their cultural, nutritional, and health benefits. However, the availability of grape leaves is constrained by viticulture practices and chemical treatments that prioritize fruit production over leaf harvesting.

Abstract:

Arbuscular mycorrhizal fungi (AMF) symbiosis has great potential in improving grapevine performance and reducing external input dependency in viticulture. However, the precise, strain-specific impacts of different AMF species on ‘Summer Black’ grapevine cuttings across multiple physiological and morphological dimensions remain underexplored. To address this, we conducted a controlled greenhouse pot experiment, systematically evaluating four different AMF species (Diversispora versiformis, Diversispora spurca, Funneliformis mosseae, and Paraglomus occultum) on ‘Summer Black’ grapevine cuttings.

Results showed that kaolin reduces leaf temperature which provokes an improvement in physiological parameters such as net photosynthesis and water use efficiency.

Abstract:

Nutritional balance methods serve as effective tools for predicting the nutritional status of grapevines and mitigating issues related to nutrient excess or deficiency, thereby influencing yield, fruit quality, and market longevity. This study investigates the effects of pre-harvest applications of calcium (Ca) and magnesium (Mg) at varying concentrations, individually and in combination, on grape quality. Pre-harvest foliar applications were conducted six times across three key phenological stages: pre-bloom, post-bloom, and fruit set. Treated clusters were stored in refrigerated conditions (

Abstract:

Macro and micro nutrient accumulation affects all stages of plant growth and development. When nutrient deficiencies or excesses occur, normal plant growth is altered resulting in symptoms such as leaf chlorosis, plant stunting or death. In grapes, few genomic regions associated with nutrient accumulation or deficiencies have been identified. Our study evaluated micro and macro nutrient concentrations in Vitis vinifera L. to identify associated SNPs using an association approach with genotype by sequencing data. Nutrient concentrations and foliar symptoms (leaf chlorosis and stunting) were com

Abstract:

The mineral composition of grapevines is of great importance for the healthy development of the plant and the production of high-quality fruit. Moreover, it is known that the mineral content enhances the vine's resistance to diseases and its tolerance to cold stress. In this study, the mineral content of the leaves of six different grape cultivars (Isabella (Vitis labrusca L.), Barış, Italia, Tekirdağ Çekirdeksizi, Trakya İlkeren, and Yalova İncisi (Vitis vinifera L.) was examined over a two-year period, with samples collected on June 15, July 15, and August 15.

Abstract:

The flowering and fruit set of grapevines are determined by many morphological, physiological, and environmental factors. Although the elemental composition of pollen grains plays a crucial role in the fruit set, there is still a considerable gap in our knowledge. To date, no study has been conducted on the elemental composition of Vitis vinifera subsp. sylvestris (hereafter V. sylvestris) pollen grains. The aim of this work was to investigate the elemental composition of pollen grains of V. sylvestris using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). The

Abstract:

Magnesium (Mg) is an essential plant macronutrient that influences various physiological processes, including photosynthesis and carbohydrate translocation. Magnesium deficiency in grapevines (Vitis vinifera L.) can impair vine performance, productivity, and fruit quality. High soil concentrations of the cationic nutrients potassium and calcium can reduce the uptake of Mg, which can induce Mg deficiency in grapevines, even with high soil Mg. This study compares the effectiveness of foliar-applied magnesium sulfate (MS) and chelated magnesium (MC) fertilisers for mitigating induced Mg deficienc

In order to preserve the health of vineyards, viticulture is heavily reliant on phytochemicals. Nevertheless, the development of eco-friendly strategies is being driven by green regulations in order to reduce their accumulation in the environment. In this regard, seaweeds have been demonstrated to be one of the marine resources with the greatest potential as plant protective agents, offering an environmentally benign alternative approach to sustainable grapevine production.

Abstract:

Abstract Xylem anatomy may change in response to environmental or biotic stresses. Vascular occlusion, an anatomical modification of mature xylem, contributes to plant resistance and susceptibility to different stresses. In woody organs, xylem occlusions have been examined as part of the senescence process, but their presence and function in leaves remain obscure. In grapevine, many stresses are associated with premature leaf senescence inducing discolorations and scorched tissue in leaves. However, we still do not know whether the leaf senescence process follows the same sequence of physiolog
