Despite Vitis vinifera L. is a drought-tolerant species—rainfed traditionally grown in a very diversity of climates—irrigation has more and more become a usual practice aimed to obtain regular yields along seasons and to control must composition. Results on vineyard irrigation are dependent on the timing, length and intensity of the water deficit....

Background and Aims Several studies have shown that cover crops restrict the development of shallow grapevine roots and reduce vigour and yield in the vineyard. The objective of this study was to evaluate the long‐term effects, after 8 years, of four soil management practices on grapevine root development and on yield in irrigated vineyards under s...

Aim: To compare grape yield prediction methods to determine which provides best results with an acceptable error earliest in the growing season. Methods and results: The grape yields predicted by six models - one for use at fruit set (FS), two for use at veraison (V1 and V2), and three for use during the lag phase (LP40, LP50 and LP60) – were compa...

Cover crops in Mediterranean vineyards are scarcely used due to water competition between the cover crop and the grapevine; however, bare soil management through tillage or herbicides tends to have negative effects on the soil over time (organic matter decrease, soil structure and soil fertility degradation, compaction, etc). The objective of this...

Winegrowing in warm, dry areas usually compromises berry growth and must composition, and therefore the composition of the resulting wines. Phenol metabolism is particularly affected. As a consequence of global warming, berry ripening processes are often delayed, reducing the likelihood of obtaining berries with the adequate composition, taste and...

In warm and dry climates, the use of porous systems should be required in order to allow a better leaf distribution inside the plant, causing more space in the clusters area and enhancing determined physiological processes so in the leaf (photosynthesis, ventilation, transpiration) as in berry (growth and maturation). Plant geometry indexes, yield...

It is already known that berry ripening is determined by the leaf area/fruit ratio, as well as temperature and leaf physiology. The aim of this work was to assess the influence of these parameters on Tempranillo cultivar throughout stage III of berry development. More specifically, the study was focused on the phase preceding the arrest of phloem t...

La preocupación por las consecuencias que puede ocasionar a la viticultura el cambio climático, se ven reflejadas en muchos de los estudios que existen en los últimos años. En las actuales zonas de producción, estos cambios podrían tener importantes consecuencias, tanto en la calidad de la uva como en su potencial productivo. El objetivo marcado en...

There are still some traditional vinegrowing areas in Spain in which water-stressed vines are considered to produce berries with the highest quality must. To assess vine response to water availability, measured in terms of crop yield, vegetative development and grape composition, five different irrigation treatments were evaluated over a five-year...

A study was conducted to determine the relationship between midday measurements of vine water status and daily water use of grapevines measured with a weighing lysimeter. Water applications to the vines were terminated on August 24th for 9 days and again on September 14th for 22 days. Daily water use of the vines in the lysimeter (ETLYS) was approx...

Vineyard leaf area is a variable that must be determined when assessing the productive potential of a vineyard and for characterizing the light and thermal microenvironments of grapevine plants. The aim of the present work was to validate the Lopes and Pinto method for determining vineyard leaf area in the vineyards of central Spain and with the ar...

This study describes a simple and rapid method for calculating the absorbed radiation (Ra) for the vineyard. The methodology Grancha-Varlet et al. (1989) was used to take into account plant and soil through four radiation components: incident, transmitted through the plant, reflected by the ground and reflected by soil and plant grouped together. B...

Canopy management determines canopy shape and spatial leaf area distribution which in turn determines vineyard productivity. There are two indexes evaluating vineyard productivity which involve leaf development: total leaf area – LAI – and external leaf area – SA –. The first one refers to total leaf area developed per m2 of soil while SA refers to...

Light intercepted by grapevines is linearly related to vineyard productivity. Radiation intercepted is also linked to vegetative development and in turn with water consume by plants. Thus, potential yield and crop coefficient – kc – for irrigation management can indirectly be predicted based on canopy light interception and vegetative development....

The relationship between leaf surface area, solar radiation, sunlight exposure and its interception by the plant was studied under very warm climate conditions at Malpica de Tajo – Toledo -. For two consecutive years three training systems were evaluated: vertical shoot positioned (VSP) with 12 shoots per meter of row, and two non-positioned system...

The relation among surface leaf area, radiation, sunlight exposure and its interception by the plant and also, thereby increasing its vegetative and reproductive yield is well knowed by far (Schneider, 1989; Smart, 1985, Sommer et al., 2000, Baeza et al., 2005). The influence of training systems caused differences in dry matter and must composition...

During the last few years, leaf water potential has been a useful tool in controlling vine water status. However, the time of measurement that could best explain short- and long-term vine responses remains a matter of discussion. The objectives of this work were to study the relationship between vine water status and vine performance and to determi...

Highly exposed cluster is a constant problem on warm climates. Training system and canopy management are key factors to attain an optimal cluster ripening by diminishing berry over ripening, berry softening, loose of berry weight and degradation of pulp and skin components. The objective of this work was to evaluate the effects of training system a...

Las zonas vitícolas españolas se caracterizan, en su mayoría, por un déficit hídrico acusado en las plantas. Debido a esto, se hace imprescindible un estudio pormenorizado del manejo del riego que permita la optimización de los recursos hídricos disponibles. El objetivo principal del ensayo fue determinar la respuesta agronómica del viñedo a dos do...

Una estrategia de riego es el conjunto de decisiones que van a determinar la cantidad y momento de aplicación del agua de riego. Para decidir la estrategia de riego es necesario fijar unos objetivos cuantitativos y cualitativos de la cosecha, así como conocer la respuesta de la planta al exceso/déficit hídrico en cada momento del ciclo.

The response of grapevine leaf net photosynthesis to light was studied in a Mediterranean environment (Madrid, Spain) during fruit ripening. Net photosynthesis was measured on primary and lateral shoot leaves located at three positions on the shoot (lower, middle and upper) and two positions on the canopy (external and inner). The light response cu...
