Influence of various rootstocks on the yield and grape composition of Sauvignon Blanc

Abstract

This influence of various rootstocks on the yield and grape composition of Sauvignon Blanc was examined. The yield on rootstock 41B/72 was 1 kg/vine or more higher than on rootstocks SO4 cl. 31, Riparia cl. 1 and Kober 5BB. The vines grafted on the Börner rootstock gave the highest weight of 100 berries (241 g). The highest seed weight of 100 berries (6.9 g) was found on rootstock 196/17 Cl, while the lowest one was on the Riparia cl. 1 (5.6 g). There was a strong, positive correlation (r = 0.91) between the berry and seed weights of vines on rootstock 41B/72 (2003). The total acidity content and the relationship between tartaric and malic acids were affected more by the weather conditions than by the rootstock. Relatively strong correlations between the grape yield and total soluble solids (r = -0.89), and between grape yield and total acidity (r = 0.76) were found in the grape juice on rootstock 41B/72 (in 2002).

Rootstock-Mediated Effects on Cabernet Sauvignon Performance: Vine Growth, Berry Ripening, Flavonoids, and Aromatic Profiles

“…Rootstocks had no significant effects on yields (Table 1). In previous studies, there were no consistent conclusions for the influence of rootstocks on yields [1,2,3,5,6,15,16,23]. Rootstocks can give rise to different reactions to yield formation in different types of soil, and it was reported that yields of different grafted vines only significantly differed in shale soil when compared to granite soil [13].…”

“…Juice titratable acidity and pH were not affected by either rootstock or season in this study (Table 2). There have been no agreed conclusions about the influence of rootstocks on titratable acidity and pH in previous studies [2,5,10,16,17,19,20,22,26,27]. Since potassium can precipitate tartrates in juice, leading to the reduction of tartaric acid, potassium in juice determines the titratable acidity and pH to a great extent.…”

“…Rootstocks can affect the biomass allocation between the root system and the shoot, and then modify the biomass distribution between the fruit and the rest of the vine [7]. Several studies documented that rootstocks imparted significant effects on vine yields [2,4,6,15,16]. Variations in shoot length and vine vigor may affect the sunlight exposure during fruit bud differentiation, thus modifying vine yields [14].…”

Challenges of viticulture adaptation to global change: tackling the issue from the roots

“…The rootstock effects on vine yield and winegrape composition have been widely evaluated since the introduction of rootstocks at the end of the 19th century, under a broad range of soil and climatic conditions for all major cultivars [aggregated information can be found, for instance in May (1994), Cordeau (1998), Fregoni (1998), Galet and Smith (1998), Hidalgo (1999), Morris et al (2007), Pulko et al (2012), Miele and Rizzon (2017) and Marín et al (2019)]. Nevertheless, considering that the performance of scions grafted to different rootstocks is not consistent, as scion × rootstock interactions occur (Clingeleffer et al 2019), and that site‐specific effects can be observed because of variation in climate and soil (Walker et al 2019), it is necessary to specifically evaluate each scion cultivar and growing conditions.…”

Effect of grapevine rootstocks on qualitative parameters of the Cerason variety

“…When speaking about rootstocks, this effect is dependent on the ratio existing between the leaf area of the plant and its yield. The balanced uptake of nutrients and water as well as the re-distribution of individual elements within the grapevine plant are closely related to changes in the phenology of plants and it is well known that these processes are significantly influenced by rootstocks (Pulko et al 2012). Resistance to yearly different conditions will be paid great attention with respect to the balanced quality of grapes.…”
