Nowadays, there is a large demand for nutrient-dense fruits to promote nutritional and metabolic human health. The production of commercial fruit crops becoming progressively input-dependent cope with the losses caused by biotic abiotic stresses. A wide variety underutilized crops, which are neither commercially cultivated nor traded on scale, mainly grown, commercialized consumed locally. These have many advantages in terms ease grow, hardiness resilience climate changes compared major...

Background and Aims: The effect of water stress on berry quality is not fully understood. This study was designed to analyse the differential phenological sensitivity Tempranillo during three stages. Methods Results: Two-year-old potted vines were exposed four levels irrigation (100, 50, 25, 0% evapotranspiration) stages (Stage I, from anthesis fruitset; Stage II, pre-veraison; III, post-veraison). Vine status monitored by means leaf potential measurements. Berry measured at harvest defined...

There is little information on the sensitivity of berry composition to early-season water stress and how it compares effects late-season stress. This study aimed quantify growth Cabernet Sauvignon grapevine at three phenological stages: anthesis fruit set, set veraison, veraison harvest. Potted vines were used facilitate imposing early in season. Four irrigation levels (0%, 25%, 50%, 100% calculated crop evapotranspiration, ET_c) applied midday leaf potential gas exchange measured....

Biostimulants represent an important category of agricultural inputs characterized by multiple functions. They are used to assist crop growth, yield and enhance the final quality produces. Their classification is generally based on claims (i.e., which services they provide crop), even though their biological effects often species-dependent highly influenced external factors growing conditions). This review provides a survey available scientific literature use biostimulant substances in fruit...

The demand for high-quality strawberries continues to grow, emphasizing the need innovative agricultural practices enhance both yield and fruit quality. In this context, utilization of natural products, such as biostimulants, has emerged a promising avenue improving strawberry production while aligning with sustainable eco-friendly approaches. This study explores influence bacterial filtrate (BF), vegetal-derived protein hydrolysate (PH), standard synthetic auxin (SA) on strawberry,...

We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and extension growth the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto different rootstocks: Nemaguard (a vigorous seed-propagated control, P. x davidiana hybrid), Hiawatha (an intermediate vigor rootstock, derived...

Sweet cherry is a high value crop and the economic success of its cultivation depends not only on yield but also fruit visual nutritional quality attributes that influence consumer acceptability, as well post-harvest performance resistance to cracking. During last few decades, growers have tried achieve these goals through exogenous applications synthetic plant hormones and/or nutrients, there growing concern about sustainability extensive use compounds in agriculture. For this reason,...

Background and Aims Climate change is advancing grape ripening decoupling sugar phenolic maturity, impacting wine typicity. The aim of this study was to test whether late leaf removal (LLR) under different watering regimes delayed harvest two Spanish red cultivars in a semi-arid temperate-warm climate. Methods Results In trials carried out eastern Spain with the Bobal Tempranillo cultivars, vines were partially defoliated above bunch zone shortly before veraison rainfed deficit irrigation...

Background and Aims Post-veraison trimming defoliation have been proposed as strategies to decrease the concentration of berry carbohydrate at harvest wine alcohol, but it is unclear which these two pruning techniques more suitable what intensity they should be applied. The aim this 3-year study was compare suitability intensities post-veraison or in controlling sugar accumulation berries Aglianico grapevines. Methods Results Five treatments were compared: defoliation, shoot a control. All...

Organic farming is an environmentally friendly management practice that excludes the use of synthetic inputs, but at same time associated with lower yields than conventional production. In attempt to compensate for yield reduction, resulting from foregoing fertilizers, we hypothesized biostimulant products could provide much-desired food security. light this, a greenhouse experiment was conducted compare and evaluate effects foliar application three different non-microbial biostimulants (a...

The changing environmental constraints require even more adaptations of management techniques in agriculture and the qualitative improvement wine production represents a sector international strategic importance. Many wine-producing areas are located environments currently suffering, or expected to experience future, water deficits that can affect grape quality. In framework CISAV project (financed by University Naples Research Funding - FRA), three years irrigation experiments (from 2021...

Weed control represents a major issue in plant cultivation containers. Manual weed is very expensive and the use of chemical herbicide or plastic mulch films has large environmental impact. The aim this study was to test efficacy an experimental biodegradable chitosan-based mulching spray controlling growth This research also studied effect on Viburnum lucidum Mill. plants for possible phytotoxic effects. compared total six treatments derived from three types (no control; herbicide,...

The European plum (Prunus domestica L.) is a worldwide distributed tree species. Italy has an ample number of traditional varieties, but many are neglected and at risk extinction. This germplasm still cultivated in rural areas spite the EU-28 crisis stone fruit sector. Traditional varieties remain poorly characterized, strongly limiting their promotion local markets, use for farm diversification, exploitation gastronomic products. In this study, we carried out investigation morphological...

Grapevine (Vitis vinifera L.) has been propagated vegetatively for hundreds of years. Therefore, plants tend to accumulate somatic mutations that can result in an intra-varietal diversity capable generating distinct clones. Although it is common winemakers request specific clones or selections planting new vineyards, relatively limited information available on the extent, degree, and morphological impact clonal traditional, highly valued grapevine varieties within production areas protected...

SummaryThe objective of this study was to evaluate the hydraulic conductance in various components peach trees grown on rootstocks with contrasting size-controlling potentials. The experiment conducted 'Crimson Lady' grafted onto two rootstocks: a semi-dwarfing rootstock, K-146-44 (P. salicina × P. persica hybrid) and vigorous Nemaguard (seed-propagated Prunus davidiana hybrid). Hydraulic leaves, stems, trunk, graft union, root system measured scion/rootstocks high-pressure flow meter. Total...

We compared growth patterns and morphology of fine roots size-controlling invigorating peach (Prunus persica (L.) Batsch) rootstocks. Peach trees were grafted on five rootstocks: a vigorous control (Nemaguard), three intermediate vigor rootstocks (K119-50, P30-135 Hiawatha), semi-dwarfing rootstock (K146-43). Minirhizotron tubes installed at the base each root images captured with minirhizotron digital camera system. Number, visible length, diameter new recorded fixed soil depths from April...

Prebloom leaf removal is a canopy management practice used in viticulture to decrease bunch compactness at harvest. However, this may not be suitable dry and warm areas because it expose bunches excessive direct sunlight, undesirably decreasing titratable acidity increasing the pH of berry juice. This study was designed test hypothesis that shading between preanthesis fruit set for Aglianico grapevines as an alternative strategy without removing leaves around bunches. treatment also thought...
