Effects of different crop load and pruning aplications on vi̇ne growing, grape yi̇eld and quality parameters of early sweet (Vitis vinifera L.) grape variety

Abstract

It is important to examine the yield and quality elements of table grape varieties. There are great differences in winter and summer pruning of the “Early Sweet” grape variety. For this reason, in the study, the effects of different crop loads and pruning processes on yield, quality characteristics and vine development of the Early Sweet (Vitis vinifera L.) grape variety were investigated. The study were designed to determine the yield-quality and vine development of the “Early Sweet” grape variety. Although there was no statistical difference between the applications in the 2023 production year, the best yield, especially in the applications carried out in the 2022 production year, was determined by the average cluster weight, cluster length and width, cluster stem width and length, number and weight of fallen berries, fresh and dry weight of the cluster skeleton, 100-berry weight, berry detachment force, water soluble dry matter% and titratable acidity parameters were determined in non-cluster treatments of 15- and 25- cluster loads on short pruning. The most appropriate pruning should be recommended as short and medium one with 25 cluster/vine.

Effetti dei diversi carichi di raccolto e delle applicazioni di potatura sulla vite, la resa dell’uva e i parametri di qualità della varietà di uva precoce dolce (Vitis vinifera L.)

E importante esaminare gli elementi qualitativi della resa delle varietà di uva da tavola. Ci sono grandi differenze nella potatura invernale ed estiva del vitigno early sweet. Per questo motivo, nello studio sono stati studiati gli effetti di diversi carichi colturali e processi di potatura sulla resa dell’uva, sulle caratteristiche qualitative e sullo sviluppo della vite nel vitigno early sweet (Vitis vinifera L.). Le pratiche nello studio sono state progettate per determinare la qualità della resa e lo sviluppo della vite del vitigno early sweet. Sebbene non vi sia stata alcuna differenza statistica tra le applicazioni nell’anno di produzione 2023, la resa migliore, soprattutto nelle applicazioni effettuate nell’anno di produzione 2022, è stata determinata dal peso medio dei grappoli, dalla lunghezza e larghezza dei grappoli, dalla larghezza e lunghezza del gambo dei grappoli, numero e peso dei chicchi caduti, peso fresco e secco dello scheletro del grappolo, peso di 100 chicchi, forza di rottura del raspo, ssc% e parametri di acidità titolabile sono stati determinati in applicazioni senza spighe di 15 e 25 grappoli su potature corte. Tuttavia, la potatura migliore per il vitigno early sweet può essere quella corta e media, con un carico di grappoli più appropriato pari a 25.

Auswirkungen verschiedener pflanzenbelastungen und schnittanwendungen auf den weinanbau, den traubenertrag und qualitätsparameter der frühsüssen (Vitis vinifera L.) Rebsorte

Es ist wichtig, die ertragsqualitätselemente von tafeltraubensorten zu untersuchen. Es gibt große unterschiede beim winter- und sommerschnitt der rebsorte early sweet. Aus diesem grund wurden in der studie die auswirkungen unterschiedlicher erntemengen und schnittprozesse auf den traubenertrag, die qualitätsmerkmale und die rebenentwicklung der rebsorte early sweet (Vitis vinifera L.) Untersucht. Die praktiken in der studie waren darauf ausgelegt, die ertragsqualität und die rebentwicklung der rebsorte early sweet zu bestimmen. Obwohl es keinen statistischen unterschied zwischen den anwendungen im produktionsjahr 2023 gab, wurde der beste ertrag, insbesondere bei den anwendungen, die im produktionsjahr 2022 durchgeführt wurden, durch das durchschnittliche traubengewicht, die traubenlänge und -breite, die traubenstielbreite und -länge bestimmt. Anzahl und gewicht der gefallenen körner, frisch- und trockengewicht des traubenskeletts, 100-körner-gewicht, stammbruchkraft, ssc-prozentsatz und titrierbare säuregehaltsparameter wurden bei der anwendung von 15 und 25 traubenbündeln auf kurzem schnitt bestimmt. Als bester schnitt für die rebsorte early sweet kann jedoch ein kurzer und mittlerer schnitt empfohlen werden, wobei die am besten geeignete traubenbeladung bei 25 liegt.

Viticulture between adaptation and resilience: the role of the Italian long-term observatories for vineyard energy, water and carbon budgets

Viticulture is exposed to a range of new stressors, that are challenging its sustainability and disrupting famous and well-established production regions. Steady increase of average temperature, recurring heat waves, altered rainfall seasonal distribution, drought spells, increased pathogens pressure, they all mix up with increased frequency, making every growing season a special challenge and calling for new approaches to cope with worrying scenarios.

Exploring the impact of yeast derivatives on aromatic and sensory profiles of white and red wines: a multifactorial analysis

Specific inactivated yeast derivatives (SYDS) are obtained from s. cerevisiae yeasts by various processes (thermal, mechanical, and enzymatic) and have diverse oenological applications to improve wine quality. However, different impacts on wine sensory and aromas were reported, depending on syds types and fractions, wine matrices, and experimental settings. Few works have examined the impact of SYDS on aromas considering also those on wine macromolecules influencing organoleptic properties.

Arbuscular mycorrhizal fungi as biomarkers of vineyard yield in Champagne

The vine is colonized by a multitude of micro-organisms (fungi, bacteria, oomycetes) mainly coming from the microbial reservoir constituted by the soil. These microorganisms have positive or negative effects on the vine (protection against pathogens, resistance to abiotic stress, nutrition, but also triggering of diseases) (Fournier, Pellan et al. 2022). In addition to these functional roles, they respond quickly to environmental changes (climate, cultural practices) which could make them good bioindicators of the functioning of the wine ecosystem.

Lean management to improve sustainability in wine sector: an exploratory study in the Prosecco DOC appellation

The contemporary wine sector confronts a formidable array of challenges, including burgeoning production costs and the constricted availability of natural resources. Heightened consumer awareness regarding sustainability issues further compounds these pressures, compelling companies to adopt more judicious resource utilization strategies. In response to these imperatives, there is a growing recognition of the need to overhaul production methodologies within the wine industry with a view to minimizing inputs and eliminating waste.
