Influence of the three main genetic backgrounds of grapevine rootstocks on petiolar nutrient concentrations of the scion, with a focus on phosphorus

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. Cabernet-Sauvignon grapevines were grafted onto rootstocks of 13 different genotypes and planted in a vineyard in three blocks. Petiolar concentrations of 13 mineral elements at veraison (berry softening) were determined. The genetic background of the rootstock had significant effects on the mineral composition of the petioles. Use of rootstocks with a genetic background including at least one Vitis riparia parent decreased the concentration of phosphorus and magnesium and increased the concentration of sulphur in the petioles of Cabernet-Sauvignon.Conclusion: Rootstocks with a Vitis riparia genetic background confer low petiolar concentrations of phosphorus and magnesium, and conversely, high petiolar concentration of sulphur.Significance of the study: The kind of rootstock onto which a grapevine has been grafted is known to influence the nutrient content of the scion. The results of the study show a significant relation between the genetic background of a rootstock and its ability to modify concentrations of phosphorus, magnesium and sulphur in the petioles of the scion under field conditions.

Rootstock and harvest season affect the chemical composition and sensory analysis of grapes and wines of the Alicante Bouschet (<i>Vitis vinifera</i> L.) grown in a tropical semi-arid climate in Brazil

“…Additionally, the alcohol content and total dry extract were statistically higher in the wines of Semester 2. According to some authors, rootstocks may differ in their ability to take up potassium, and they can influence grape and wine mineral composition (Gautier et al, 2020;Miele and Rizzon, 2017;Kodur, 2011).…”

Grapevine Microbiota Reflect Diversity among Compartments and Complex Interactions within and among Root and Shoot Systems

“…Today more than 80% of vineyards employ grafting [36]. Previous research on grafted grapevines has shown that rootstock genotypes influence scion phenotypes such as leaf ionomic profiles [37,38], shoot gene expression [39], and leaf morphology [40]. Interestingly, grapevine rootstock genotypes have distinct bacterial rhizosphere communities [41,42], and the influence of rootstock genotype on root-associated microbiota appears to increase with vine age [43].…”

“…Today more than 80% of vineyards employ grafting (Ollat et al 2016). Previous research on grafted grapevines has shown that rootstock genotypes influence scion phenotypes such as leaf ionomic profiles (Lecourt et al 2015;Gautier et al 2020), shoot gene expression (Cookson and Ollat 2013), and leaf morphology (Migicovsky et al 2019). Interestingly, grapevine rootstock genotypes have distinct bacterial rhizosphere communities (D'Amico et al 2018;Marasco et al 2018), and the influence of rootstock genotype on root-associated microbiota appears to increase with vine age (Berlanas et al 2019).…”
