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.

Unveiling the viticultural heritage of Rachaya, Lebanon: genetic, ampelographic and chemical profiling of local grape varieties

Located in the western bekaa region of lebanon, rachaya is known for its extensive history of viticulture and ideal mediterranean conditions for grapevine cultivation. Despite the area’s importance in grapevine production, there is limited knowledge about the local grape varieties grown there. In this work, we conducted a detailed analysis of five local grapevine varieties in the area, obeidy, kassoufi, foddeh, aswadi, and maryami, of which little is currently known, in comparison to a set of international varieties.

Grapevine genotypes with potential for reducing the carbon footprint in the atmosphere and cultivation in a biological system

The concentration of CO2 in the atmosphere is increasing from year to year. Taking into account the calculations of the greenhouse gas inventory, it was found that approximately 70% of CO2 in the atmosphere is absorbed by vegetation (forests, agricultural land, etc.).

Vine selection in France: An assessment after more than 60 years of work

It was at the end of the second world war that professor Branas laid the foundations of french vine selection. He was also behind the creation of domaine de vassal (1949) and antav (1962), which were to become the bridgeheads of the french strategy for the conservation, selection and multiplication of viticultural diversity. Initially based on visually virus-symptom-free massal selections, with the main aim of providing healthy, clearly-identified plant material, the process evolved as knowledge gained towards clonal selection.

Mineral-wine profile and AI: wine authentication and identification

Enhancing the mineral wine profile: from authentication to identification by artificial intelligence for enhanced security. Analysis of a wine’s mineral concentration profile provides a distinctive fingerprint for each cuvée. Unlike organic profiles, this identification signature remains stable over time and can be deciphered using direct analysis by inductively coupled mass spectrometry (icp-ms).

Wine industry, digital transformation, and sustainability: a systematic literature 

This paper aims to (i) identify the state of the art regarding digital transformation in the transition to sustainability in the wine industry, (ii) analyze the adoption of digital technologies at different stages of the winemaking process and their contribution to the triple bottom line of sustainability, and (iii) present a research agenda that facilitates the development of the field, providing contributions to both literature and managerial practice.
