“…It seems that spur pruning influences the marketable yield by affecting cluster number rather than cluster or berry weight, as they did not vary significantly between the two training systems in both varieties. Similar results regarding the non-significant effect of the training system on berry quality and composition were previously reported [7]; however, others observed changes in berry composition when using different training systems [5,12]. Varieties respond differently to the pruning systems, so establishing a variety-specific standardization of pruning is crucial to sustaining its productivity and fruit quality [13].…”

The type of training system affects vine growth and productivity; however, there is a lack of knowledge on the suitability of pruning systems for some recently introduced (Vitis vinifera L.) cultivars. In this study, we provide the growers with science-based information about the response of two table grape variates to cane and spur-pruning systems to develop the best cultural practices. In 2013, a vineyard was established at Kearney Agriculture Research Center, Parlier, California using “Autumn King” and “Scarlet Royal” table grapes (Vitis vinifera L.) grafted on Freedom rootstock. The performance of the three-year-old vines was assessed under two pruning systems, Quadrilateral cordon training (spur-pruning) and Head training (cane pruning). Data from the 2016 and 2017 seasons showed no significant differences in leaf area, chlorophyll content, Normalized Difference Vegetation Index (NDVI), and pruning weight between the two pruning systems in both cultivars. In both seasons, marketable yield did not vary between the two pruning systems in the Scarlet Royal. However, Autumn King marketable yield was significantly reduced when using the Quadrilateral cordon training (spur-pruning). Petioles nutrient analysis at bloom showed a non-significant increase in nitrate content in the cane pruned vines of both varieties. No significant difference was observed in cluster weight, berry physical, or chemical composition. It seems that both training systems could be used for Scarlet Royal. However, the cane pruning system in Autumn King produced higher yield without affecting cluster and berry quality. The different responses of the two varieties could be due to the genetic background and growth behavior. Our data confirmed the notion that the different responses to the training methods by various grape varieties may involve the genetic background, growth behavior, as well as nutrient uptake and usage by the vines. Establishing the proper training system for each grape variety is essential.

“…In the cane pruned vines, the basal half of the canes exhibited more blind buds and the growth patterns variability reduced as cane length decreased [6]. Spur-pruning of Cabernet Sauvignon vines resulted in higher shoot growth and pruning weight [7]. Moreover, a higher bud break percentage was noticed compared to cane pruning.…”

“…Regarding the effect of spur or cane pruning on fruit composition of cabernet sauvignon grapes, Peppi and Kania found no significant differences in terms of both total phenol content and phenol composition of seeds. This observation led us to think that the pruning technique had only a limited effect on grape seed tannin content and composition . Furthermore, PA seed tannin content of corot noir grapes seems to be not affected by cluster or shoot thinning .…”

Phenolic compounds are among the most important quality factors of wines. They contribute to the organoleptic characteristics of wine such as color, astringency, and bitterness. Although tannins found in wine can come from microbial and oak sources, the main sources of polyphenols are grape skins and seeds. Since the 1960s, this subject has been widely studied by a large number of researchers covering different types of wine, climate conditions, growing practices, and grape varieties. As these works have been conducted under different conditions, the data collected can be conflicting. Moreover, even though the biosynthesis of the major proanthocyanidins units (+)-catechin and (−)-epicatechin is well-known, the mechanism of their polymerization remains unexplained. This is why the question remains: what factors influence the biosynthesis, the quantity, and the distribution of tannins in grape seeds and how can winemaking processes impact the extractability of seed tannins in wine?
