Yield prediction is crucial for the management of harvest and scheduling wine production operations. Traditional yield methods rely on manual sampling are time-consuming, making it difficult to handle intrinsic spatial variability vineyards. There have been significant advances in automatic estimation vineyards from on-ground imagery, but terrestrial platforms some limitations since they can cause soil compaction problems sloping ploughed land. The analysis photogrammetric point clouds...
In recent years, there has been a resurgence of interest in grapevine pruning. This growing focus emerged as response to the long-term issues that poor pruning practices have caused vineyards. Decades neglecting fundamental principles pruning, driven by on increasing yields and reducing costs, probably contributed significantly vineyard decline. renewed attention seeks reverse damage done practices, emphasising importance proper wound management, sap flow preservation, more thoughtful...
Canopy management operations, such as shoot thinning, leaf removal, and trimming, are among the most relevant agricultural practices in viticulture. However, supervision of these tasks demands a visual inspection whole vineyard, which is time-consuming laborious. The application photogrammetric techniques to images acquired with an Unmanned Aerial Vehicle (UAV) has proved be efficient way measure woody crops canopy. Consequently, objective this work was determine whether use UAV...
Aim: An advance in grapevine phenological stages (including ripening) is occurring worldwide due to global warming and, the hottest seasons, already results a lack of synchrony between sugar and phenolic ripeness, leading unbalanced wines. In order cope with this fact, general effort being made by researchers growers aiming at delaying ripening through cultural practices, particularly under warm growing conditions, where these effects are more deleterious. The aim work evaluate which extent...
Grapevine pruning is an agronomical operation required to regulate growth and yield, improve fruit quality, maintain plant health vigour. However, the intensification of crop in last decades, driven by efforts increase productivity decrease costs, has led reduced attention this operation. The aim study was investigate whether different styles during first years vineyard training affect grapevine development. Three were followed a newly planted cv. “Tempranillo” for four consecutive seasons:...
A quick and accurate sampling method for determining yield in peach orchards could lead to better crop management decisions, more insurance claim adjustment, reduced expenses the industry. Given that sample size depends exclusively on variability of trees orchard, it is necessary have a objective way assessing this variability. The aim study was use remote sensing detect spatial within classify into homogeneous zones constitute strata decrease size. Five mature with different degrees were...

Abstract The selection of genotypes best adapted to environmental conditions has traditionally focused on agronomic and grape composition parameters. However, classify the most climate change conditions, aim must be focus ecophysiological responses that will ultimately determine their performance. variability in water use efficiency 13 Grenache over three‐seasons was assessed under field at leaf, plant level.

Warming trends over the winegrowing regions lead to an advance of grapevine phenology, decreased yield and increased sugar content with a lower polyphenol content. We hypothesized that different leaf removal timings may counteract these effects. A two-year experiment was conducted in La Rioja (Spain) Vitis vinifera L. cv. Grenache trained open-vase system. Trial consisted complete block design two treatments differing moment manipulation: i) severe treatment after fruit set (ELR); ii) at...
The study of the natural abundance nitrogen-stable isotopes is an aspect viticulture research that has received limited attention. While stable carbon, oxygen and hydrogen have significant attention, nitrogen isotope ratio (δ15N) remains a less studied yet potentially informative parameter. This paper explores implications δ15N measurements in grapevines, shedding light on its utility as indicator for sources, plant water status, within-field variability. examines influence dose, sampling...
Soil management through cover crops can influence the cycle of nutrients, promote water infiltration, decrease erosion, and enhance soil microbiota biodiversity, improving grapevine performance. However, area under vines tends to be left bare by applying herbicides or tillage avoid competition with crop in semi-arid climates. Use covers under-vine might an alternative these practices aiming at quality health improvement. The aim this research was study implications (cultivation crops) on...
Grafting Vitis vinifera L. (wine traditional cultivars) onto North American grapevine species or hybrids is a common practice in viticulture given their tolerance against phylloxera (Daktulosphaira vitifoliae). However, rootstock genetic background affects the response of grapevines to environmental stresses and ability for establishing symbiotic relationship with microbial communities, more specifically arbuscular mycorrhizal fungi (AMF). The aim this study was evaluate Monastrell variety...
One of the most important effects climate change in wine-growing areas is advance phenological stages, especially concerning early berry ripening. In hottest seasons, this results a lack synchrony between sugar and phenolic ripeness. order to cope with fact, general effort being made by researchers growers aiming at delaying ripening through different strategies. proposed approaches application elicitors.

Spanish pear germplasm collections are crucial for preservation, research, and breeding efforts. However, genetic diversity structure is unknown at national level. A coordinated project analyzed 1251 accessions from 7 using an internationally recognized set of 14 SSRs to enhance the utilization these collections. Key findings included identification 760 unique genotypes (490 diploids 270 triploids). Notably, represented by a single accession accounted 49% total, indicating high vulnerability...
