Special Issue Information

Dear Colleagues,

In arboriculture, the vine is one of the most cultivated plants. The total surface planted globally is estimated at 7.5 x 106 ha, and around 7.5 x 106 metric tons of grapes are produced annually (according to the OIV). Grapes are used as fresh (36%), raisins (7%), or for the production of wine (57%). Although global vineyard hectares have declined over the past 20 years, particularly in the Mediterranean area, grape production has increased progressively from 6.0 to 7.5 x 106 metric tons. Grape usage varies considerably from region to region, and from country to country. For example, most grapes grown in Europe are used in wine production, whereas in China or India grapes are mostly used as a fresh fruit crop. Two challenges concern the world of viticulture in years to come: (i) the sustainability of crops, and (ii) the contrast to climate change as a stressor.

Both challenges are difficult to overcome. The survival of some historic wine-growing regions could be at risk, and in particular the quality of production could be compromised or greatly modified.

The proposed Special Issue on “Advances in Viticulture production” aims to present advanced studies, methods, tools, and cutting-edge innovations applied in the field of grape production. I look forward receiving to your manuscripts and am eager to share your results with the community of researchers, students, technicians, winegrowers, and enthusiasts of the world of viticulture. Potential topics include, but are not limited to: new techniques to manage production factors; methods for the early estimation of yield and productivity; stress management and reduction of water consumption; integrated and organic management of pests, diseases, and weeds; IOT and DSS systems; precision viticulture for sustainable vineyard management; and automation and autonomous driving in viticulture mechanization.

The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach. A set of 192 bunches from four cultivars, collected at sites located in Portugal and South Africa, were imaged using a conventional digital RGB camera, followed by image analysis, where several bunch features were extracted, along with physical measurements performed in laboratory conditions. Image data features were explored as predictors of bunch weight, individually and in a multiple stepwise regression analysis, which were then tested on 37% of the data. The results show that the variables bunch area and visible berries are good predictors of bunch weight (R2 ranging from 0.72 to 0.90); however, the simple regression lines fitted between these predictors and the response variable presented significantly different slopes among cultivars, indicating cultivar dependency. The elected multiple regression model used a combination of four variables: bunch area, bunch perimeter, visible berry number, and average berry area. The regression analysis between the actual and estimated bunch weight yielded a R2 = 0.91 on the test set. Our results are an important step towards automatic yield estimation in the vineyard, as they increase the possibility of applying image-based approaches using a generalized model, independent of the cultivar.

Compact bunches have been often associated with higher susceptibility to Botrytis cinerea and therefore reduction in berry quality in grapevine. The objective of this study was to evaluate three management methods (early leaf removal, gibberellic acid, and their combination) for reducing bunch compactness in Vitis vinifera cv. Pinot gris trained in two different training systems with contrasting vigor (Guyot and pergola). Treatments were applied at BBCH 62 or BBCH 65 and yield components, total soluble solids, fruit set, and bunch compactness parameters were evaluated. Both treatments individually reduced berry number, mean bunches weight and bunches compactness as well as yield per vine when compared to control-untreated vines. However, no major differences were observed when both the treatments were applied in combination for Guyot or pergola although a higher reduction in yield was detected for Guyot and a significant increase in total soluble solids was observed in pergola. Our study suggests that intense leaf removal and gibberellic acid applied at early flowering can help reducing bunch compactness in Pinot gris and showing it in two training systems. In particular, leaf removal represents a valuable alternative to plant growth regulators (i.e., gibberellic acid) as applicable in organic viticulture. Full article

This work investigated the structural, biochemical, and molecular characteristics of grape skin cell wall during ripening, related to susceptibility to Botrytis cinerea. The comparative study between the two main grape cultivars in Champagne region, Pinot noir and Chardonnay, quantified: (1) the maturity and physical profile of grape skin; (2) the morphological characteristics; (3) soluble pectic polysaccharides located in grape skin cell walls; and (4) the gene expression of the two main degrading enzymes (VvPME1 and VvPG1) and PME activity. During the maturation period, the grape skins of the two cultivars appear different in their structure and composition. Chardonnay is characterized by higher relative humidity (RH) and level of VvPG1 expression, lower disease incidence and penetrometry values, and thicker cell walls than Pinot noir skins. Thus, the cell wall composition is sufficiently different between grape varieties from the same area to allow their discrimination and could be used to better manage the harvest date. Full article

Grafting cold-hardy hybrid grapevines may influence their attributes under different pedoclimatic conditions and may also contribute to cold-hardiness, influence plant physiology, and affect yield and fruit composition. In a six-year study, we evaluated bud survival, plant development, nutrient deficiencies, yield, and fruit composition for three cold-hardy grape varieties: Frontenac, Frontenac blanc, and Marquette. The grape varieties were grafted on four rootstocks: 3309C, SO4, Riparia Gloire, and 101-14. The final combinations were own-rooted. The six-year research period indicated that cold-hardy hybrids were affected differently by each rootstock. Magnesium deficiency was lower for grafted Frontenac and Frontenac blanc compared with own-rooted vines, but bud survival and grapevine development were not affected by rootstock. Moreover, results related to yield components showed that there are significant differences between rootstocks and own-rooted vines. Frontenac was the least affected grape variety compared to Frontenac blanc and Marquette, where only cluster weight and berry weight were impacted. Overall, for the two Frontenac varietals, we also observed a greater maturity for fruits of vines grafted on 101-14 and 3309C compared with own-rooted vines. Grafting affected fruit composition for Marquette differently, where the lowest grape maturity was observed for fruits on vines grafted on SO4. This study demonstrates that rootstocks affect cold-hardy hybrids, highlighting their potential under eastern North American conditions. Full article

As a representative economic crop with the potential for long-term sustainable development, grapevines (Vitis vinifera L.) bring direct economic benefits to the people, and the indirect ecological benefits produced by grapevines cannot be ignored. This study utilized relevant statistical data from the government sectors and data obtained at vineyards and wineries through interviews and surveys. The value of the ecosystem service of the grape industry in soil-burial over-wintering areas was first evaluated from four first-level indicators types and 10 s-level indicators types, using Hongsibu of the eastern foothill of Helan Mountain, Ningxia, as an example. The results show that the total current benefits of the grape industry ecosystem service function in Hongsibu are ¥ 1067 million. The direct economic benefits are ¥ 660 million and indirect ecological benefits are ¥ 407 million. The value ranking of the first-level function types is as follows: supply services > cultural services > support services > regulatory services. The ranking of the value of second-level function types is as follows: food production > ecological poverty alleviation > biodiversity > carbon fixation and oxygen release > ecotourism > air purification > nutrient accumulation > water conservation and efficiency > water holding > soil conservation. Cultivation measures (such as burial-free cultivation technology, inter-row grass technology, and suspending grape branches after winter pruning technology) increased the value of the service function of the grape ecosystem and explored some potential benefits. The results indicated the necessity of assessing ecosystem service value of the grape industry, which could enable people to realize the direct economic benefits as well as the ecological benefits. Meanwhile, the positive effects of cultivation techniques on the value of ecosystem service function were demonstrated in soil-burial over-wintering areas. This study provides important reference value and comprehensive guidance for the healthy and sustainable development of the grape industry. Full article

Plant diseases and pests cause a large loss of world agricultural production. Downy mildew is a major disease in grapevine. Conventional techniques for plant diseases evaluations are time-consuming and require expert personnel. This work investigates novel sensing technologies and artificial intelligence applications for assessing downy mildew in grapevine under laboratory conditions. In our methodology, machine vision is applied to assess downy mildew sporulation, while hyperspectral imaging is used to explore its potential capability towards early detection of this disease. Image analysis applied to RGB leaf disc images is used to estimate downy mildew (Plamopara viticola) severity in grapevine (Vitis vinifera L. cv Tempranillo). A determination coefficient (R2) of 0.76 ** and a root mean square error (RMSE) of 20.53% are observed in the correlation between downy mildew severity by computer vision and expert’s visual assessment. Furthermore, an accuracy of 81% is achieved to detect downy mildew early using hyperspectral images. These results indicate that non-invasive sensing technologies and computer vision can be applied for assessing and quantify sporulation of downy mildew in grapevine leaves. The severity of this key disease is evaluated in grapevine under laboratory conditions. In conclusion, computer vision, hyperspectral imaging and machine learning could be applied for important disease detection in grapevine. Full article

Ripeness estimation of fruits and vegetables is a key factor for the optimization of field management and the harvesting of the desired product quality. Typical ripeness estimation involves multiple manual samplings before harvest followed by chemical analyses. Machine vision has paved the way for agricultural automation by introducing quicker, cost-effective, and non-destructive methods. This work comprehensively surveys the most recent applications of machine vision techniques for ripeness estimation. Due to the broad area of machine vision applications in agriculture, this review is limited only to the most recent techniques related to grapes. The aim of this work is to provide an overview of the state-of-the-art algorithms by covering a wide range of applications. The potential of current machine vision techniques for specific viticulture applications is also analyzed. Problems, limitations of each technique, and future trends are discussed. Moreover, the integration of machine vision algorithms in grape harvesting robots for real-time in-field maturity assessment is additionally examined. Full article

Due to the particularity of the continental monsoon climate in China, more than 90% of the wine grape cultivation areas require vines to be buried in winter for a burial period that can extend to half a year. Additionally, traditional vine cultivation practices can expose the surface of the soil during winter, easily leading to soil erosion. To meet the restrictive factors for viticulture in the Chinese cold climate zone, a new sustainable viticulture strategy called crawled cordon mode (CCM) has been developed. CCM includes crawled cordon training (CCT), physical methods of flower and fruit thinning, winter suspension of shoots, the use of a biodegradable liquid film, and covering of grass and branches for simplified management of vineyards. This article summarizes the specific implementation methods of the main measures of CCM and their significant effects on the quality of grapes and wine, ecological environment, and costs, and aims to provide inspiration for the study of sustainable and eco-friendly cultivation measures for vineyards in other cold climate zones.
