Background and Aims: The number of pre-bloom source leaves is a primary determinant subsequent fruitset. Accordingly, we tested whether pre- post-bloom hand (HD) mechanical (MD) defoliation are effective in limiting the yield high-cropping cultivar such as Sangiovese 3-year field study. Methods Results: first six basal any laterals were removed by hand, same area was subjected to MD, latter removing 48.3% leaf manually. Both treatments significantly reduced fruitset, per shoot, bunch weight,...
Abstract Fine roots vary dramatically in their functions, which range from resource absorption to within-plant transport. These differences should alter availability root-associated microorganisms, yet most root microbiome studies involve fine homogenization. We hypothesized that microbial filtering would be greatest the distal roots. To test this, we sampled of six temperate tree species a 23-year-old common garden planting, separating by branching order. Rhizoplane bacterial composition...
Abstract Spotted lanternfly ( Lycorma delicatula White; SLF) is a phloem‐feeding planthopper invasive to the Eastern United States that can feed on range of wild and cultivated plant species. Since its 2014 introduction in States, large infestations subsequent economic damage have been reported grapevines, but no studies detailed grapevine physiological responses SLF phloem feeding. This study investigated grapevine‐SLF interactions, detailing how different infestation densities affect leaf...
Abstract Lycorma delicatula, known as the spotted lanternfly, an insect native to Asia, feeds on a broad range of plant species in United States, including tree heaven, black walnut, silver and red maple, grapes. As early 2024, grape growers New York State have not reported lanternfly-related issues. In contrast, Pennsylvania experienced significant losses during years infestation, with some vineyards replanting due vine death caused by lanternfly. Over time, developed management strategies,...
Background and Aims The objective of this study was to assess the effect root pruning (RP) annual under-trellis cover crops (UTCC) on vegetative growth physiological processes in Cabernet Franc (Vitis vinifera L.) grapevines grafted 3309C rootstock. Methods Results Five root-zone management treatments, namely vegetation-free strip control (C), RP three distinct UTCC [annual ryegrass (AR), buckwheat, (BW) turnip (TP)] were evaluated compared over seasons a vigorous vineyard Northeastern USA....
Abstract Traditionally, fine roots were grouped using arbitrary size categories, rarely capturing the heterogeneity in physiology, morphology and functionality among different root orders. Fine with functional roles are separated microbiome‐focused studies may result confounding microbial signals host‐filtering across microbiome compartments. Using a 26‐year‐old common garden, we sampled from four temperate tree species that varied sorted them into absorptive transportive roots. The...
The aim of our study was to compare soil evaporation (E<sub>s</sub>) versus cover crop (<i>Festuca arundinacea</i> var. barfelix) evapotranspiration (ET<sub>cc</sub>) within a vineyard ecosystem and investigate the effect mowing in reducing evapotranspiration, and, hence, its below-ground competitiveness. carried out 2-year-old Sangiovese (<i>Vitis vinifera</i> L.) vineyard, grafted SO4, Bologna, Italy. Mini-lysimeters portable gas-exchange chamber system were used relation bare management...
Spring frosts and subsequent crop losses threaten the economic sustainability of fruit producers all over world. This study used a controlled-freezing technique to impose post-budburst freezing stress grapevine shoots forced from one-node cuttings [‘Albariño’, ‘Cabernet Franc’, Sauvignon’, ‘Pinot Grigio’ ( Vitis vinifera )] whole plants [‘Noiret’ hybrid)]. Our goal was investigate incidence freeze injury among cultivars, stage phenological development, potassium salt-based fertilizer (KDL)...
Fruit-zone leaf removal is typically applied in cool and humid regions to improve grape wine quality, while reducing disease pressure. When fruit-zone early the season, before bloom [early (ELR)], it also reduces fruit-set, cluster compactness, susceptibility bunch rot, a complex that involves fungi ( Botrytis cinerea , Aspergillus sp., Penicillium sp.) bacteria Acetobacter sp.). Over 2 years (2015–16), we tested whether ELR mechanically [mechanical defoliation at stage E-L 18 (MD-I)] would...
Background and Aims: Although cover crops are largely used in vineyards, limited information is available on the amount of water they use. The aim this study was to quantify crop evapotranspiration (ETcc) inter-row a Concord (Vitis labruscana Bailey) vineyard. In addition, hypothesis that ETcc could be accurately estimated through relationship with incident solar radiation reference tested. Methods Results: ET cc measured using mini-lysimeters located across single curtain- Geneva double...
Abstract BACKGROUND Spotted lanternfly, an invasive planthopper which was first found in 2014 the eastern USA, has become a significant pest to vineyards. Sap‐feeding by this been associated with plant stress and yield declines, current management depends entirely on prophylactic use of insecticides. Our study explored two new integrated (IPM) tactics against spotted lanternfly reduce negative effects frequent chemical applications: exclusion netting perimeter applications RESULTS Exclusion...
Field studies were conducted in 2014 and 2015 on <i>Vitis vinifera</i> cvs. Lemberger Riesling interspecific hybrid Noiret Traminette to evaluate the effectiveness of two sprayable products for reducing postbudburst freeze damage without impacting grape production, fruit composition, wine chemistry, or sensory perception. The treatments consisted a) one application a vegetable oil-based adjuvant (Amigo) during dormant season delay budburst reduce chance frost damage; b) potassium fertilizer...
A traditional crop load regulation technique, cluster thinning (CT), was compared to a more innovative early leaf removal (ELR) applied either at trace bloom (TBLR) or fruit set (FSLR), on high-yielding and vigorous <i>Vitis vinifera</i> cv. Grüner Veltliner. Treatment effects key production parameters, <i>Botrytis</i> bunch rot, tolerance winter temperatures, costs were evaluated an untreated control over two years. Compared CT, we hypothesized that ELR would improve composition, reduce...
Purpose This study aims to characterize several wine consumer segments who were “likely” sample (i.e. taste before purchasing) from vineyards using cover crops, a sustainable production practice that reduces herbicide applications, and identify those with greater probability of being viable target market based on survey responses. Design/methodology/approach A total 956 consumers the Mid-Atlantic boarding US states separated into an ECHAID (exhaustive Chi-square automatic interaction...
The spotted lanternfly, a newly invasive insect in the U.S. that is great concern for grapevine industry, produces damage on its host plants through aggressive feeding, using piercing and sucking method to feed phloem of plants. In eastern US, adult SLF can invade vineyards fruit ripening until end growing season; however, it still unclear how prolonged late-season feeding affect health grapevines, as well responses this extensive damage. Thus, we have performed comprehensive genome-wide...
<h3>Abstract</h3> <h3>Background and goals</h3> Early leaf removal (ELR) is a canopy management practice that can reduce bunch rot improve fruit maturity by modifying cluster architecture zone microclimate. The goal of this study was to identify an ELR threshold balances improvements quality reductions in yield for highly vegetative high-yielding <i>Vitis vinifera</i> cultivar grown the eastern United States, Grüner Veltliner. <h3>Methods key findings</h3> Over two consecutive years, we...
Root-associated microbial communities are increasingly recognized as key contributors to plant function, but we still understand little about the factors driving interactions between microbes and individual roots. To have thorough understanding of this system, must consider immense functional spatial heterogeneity roots within complex root systems. In Viewpoint, describe a prototype study in which map analyze root-associated throughout woody system. Our efforts demonstrate how spatially...
Rotundone was recently identified as the compound that imparts black pepper aroma in several winegrape cultivars. This two-year study aimed to identify presence of rotundone Noiret (interspecific hybrid <i>Vitis</i>) and determine impact fruit-zone leaf removal on concentrations fruit wine. The relationship between intensity concentration wine also explored. An undefoliated control (CON) compared a maintained sunlight exposure (MSE) treatment, where leaves were periodically removed from...
