Abstract:
... Stilbenes are a family of phenolic secondary metabolites that are known for their important roles in plant protection and human health. Numerous studies show that vine shoots, one of the most abundant winery wastes, could be used as a source of bioactive compounds such as stilbenes. The predominant stilbenoids in vine shoots are trans-resveratrol (Rsv) and -viniferin (Vf), whose content varies dep ...

Abstract:
... Vine weevil, Otiorhynchus sulcatus F. (Coleoptera: Curculionidae), is an economically important insect pest of horticultural crops. To identify an effective and reliable monitoring system for adult vine weevil, this study investigated the influence of colour, height and entrance position on the efficacy of a model monitoring tool using modified paper cups as refuges. Vine weevil preferences were d ...

Abstract:
... In precision viticulture, the intra-field spatial variability characterization is a crucial step to efficiently use natural resources by lowering the environmental impact. In recent years, technologies such as Unmanned Aerial Vehicles (UAVs), Mobile Laser Scanners (MLS), multispectral sensors, Mobile Apps (MA) and Structure from Motion (SfM) techniques enabled the possibility to characterize this ...

Abstract:
... The family Vitaceae has a wide distribution, occurring in temperate, subtropical, and tropical climates. Vine members of the family thrive in different types of vegetation. Currently, the family includes five recognized tribes: Ampelopsideae, Cisseae, Cayratieae, Parthenocisseae, and Viteae. This study describes the pollen morphology of representatives of Ampelopsideae, Cayratieae, and Parthenocis ...

Abstract:
... Late pruning is a field technique that has recently been proposed to mitigate the advance in phenology produced by global warming. However, contrasting effects have been observed depending on the cultivar and the date of pruning evaluated. In this work, our aim was to evaluate the effects of delayed pruning on phenology, vegetative growth, yield components, and crop evapotranspiration in cv. Malbe ...

Abstract:
... 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 v ...

Abstract:
... The number of berries is one of the most relevant yield components that drives grape production in viticulture. The goal of this work was to estimate the number of actual berries per grapevine using computer vision and deep learning in commercial vineyards. Images from the visible range (RGB) were acquired from a set of 96 grapevines (Vitis vinifera L.) at pea-size berry stage using a red, green a ...

Abstract:
... The woodland invasive species bitter vine (Mikania micrantha Kunth) is widely distributed in southern Asia. Since it adversely affects vegetation growth and ecological functions, it is imperative to develop an automated detection method to investigate the species’ expansion in large areas. We obtained training and test samples in the Zengcheng woodland, Guangzhou Province, China, and used aerial i ...

Abstract:
... Kudzu is a rapidly growing ornamental vine, which continues to invade forests and other natural ecosystems in many parts of the United States including the state of Oklahoma. Effective quarantine regulations and their strict enforcement can help prevent invasive species from spreading, but public awareness, support, and early detection are keys for long-term success. The goal of this study is to u ...
... Three vigor zones, identified in a Barbera vineyard by remote sensing at full canopy, were carefully ground-truthed to determine, over 2 years, the relative weight of soil factors in affecting within-field variability, and to investigate vigor zone influence on dry matter (DM) and nutrient partitioning into different vine organs. Regardless of season, high vigor (HV) achieved stronger vine capacit ...
... Multivariate statistical models can be simplified by assuming that a pattern of conditional independence is presented in the given data. A popular way of capturing the (conditional) independence is to use probabilistic graphical models. The relationship between strongly chordal graphs and m-saturated vines is proved. Moreover, an algorithm to construct an m-saturated vine structure corresponding t ...

Abstract:
... Biomass-fuelled Combined Heat and Power Generation (CHP) systems can efficiently convert chemical energy contained in biomass into electricity and heat. Currently there is a large number of abandoned forests and biomass of agroforestry origin that is not being used. The use of residual biomass as a source of energy in CHP systems is presented as a particularly attractive alternative for energy obt ...

Abstract:
... Water availability in vineyards varies in space and time. The spatiotemporal variability of water availability to vines is affected by terrain, meteorology, and irrigation. This study aimed to analyze the response of vegetative and reproductive attributes of vines to spatiotemporal variability in water availability. We quantified the spatial autocorrelation of terrain covariates and grapevine attr ...

A climate-resilient, root-based sweetpotato planting material (SPM) conservation method called “Triple S” or “Storage in Sand and Sprouting” has created timely access to sweetpotato planting material in areas with a prolonged dry season in Uganda and Tanzania. The aim of this study was to validate and optimize the Triple S method for conservation of sweetpotato planting material in dry areas of so ...

Abstract:
... The world’s changing climate is placing great pressure on the resources for sustainable viticulture. With this, it has become necessary to investigate grape varieties that are well adapted to hot climates. This study investigated whether two Cypriot varieties (Xynisteri and Maratheftiko) responded differently to Shiraz and Sauvignon Blanc grown under different irrigation regimes (full, 50% and 25% ...

This study investigated the effectiveness of cellulose nanocrystals (CNCs) derived from Kudzu (Pueraria montana) vine to reinforce to starch-based films. In addition, the essential oil was incorporated into these nanocomposite films to evaluate further improvement in film properties and applications. Different packagin ...
... While weed management is often thought of as an agricultural issue, weeds are also problematic for homeowners, public space managers and utilities. In these situations, weeds are typically hand‐pulled, mechanically treated or managed via herbicides. Hand pulling and mechanical treatments are labour‐intensive, and all control methods may have unintended off‐target impacts, necessitating new alterna ...

Given the periodic structure of goblet vineyards, the RGB color coded parcel image is analyzed using proper processing techniques in order to determine the locations of living and missing vines. Vine characterization is achieved by implementing ...
... The development of inter-row wildflower meadows in vineyards could restore and preserve biodiversity as well as enhance the local rural landscape character. Herein, the prospect of inter-row development of a wildflower meadow from spontaneous vegetation growing within a table grape ‘Sultanina’ vineyard was studied for two years through the effect of different intensities of harvest on the meadow c ...
