Maximum daily trunk shrinkage is a common measurement in irrigation scheduling of fruit trees. But the strong relationship between these measurements and the environment severely limit field applications. Reference baselines are the solution for understanding the influence of environmental conditions. Nevertheless, the extrapolation out of the...

El agua es un bien escaso en muchas zonas de nuestra región, donde el régimen de precipitaciones es muy bajo, y el volumen de agua disponible para el aprovechamiento agrícola es muy limitado. Por ello el uso racional de los recursos hídricos debe ser un criterio fundamental en la implantación de nuevos cultivos. La selección de especies es...

There is an increasing interest in preserving and, if possible, increasing wild bee populations as evidenced by increasinginvestigations into providing supplemental nesting resources, commonly called bee hotels. The study presented herewas carried out in 2017 and 2018 with two objectives: a) to understand the role that insect refuges could have...

Falcarinol (9Z-heptadeca-1,9-diene-4,6-diyn-3-ol; 1) is a polyacetylene commonly found in several plant families. The absolute configuration of naturally occurring 1 is not clear and contradictory results have been reported in the literature. Determination of the absolute configuration of 1 from Pastinaca sativa L. was carried out. Isolation of...

Intensification of olive production could suppose an increase of natural resources consumption as well as an acceleration of soil degradation. Studies of soil and trees combining different strategies of water management and fertilization to solve these drawbacks are scarce and contradictory. The aim of this work was to describe the effect of...

Potassium (K) is closely related to plant water uptake and use and affects key processes in assimilation and growth. The aim of this work was to find out to what extent K supply and enhanced compartmentation might improve water use and productivity when tomato plants suffered from periods of water stress. Yield, water traits, gas exchange,...

La variación del diámetro del tronco es un sistema que se está sugiriendo para la programación del riego de varias especies frutales pero que no tiene resultados claros en olivo. El parámetro de estos ciclos más tradicionalmente empleado es la máxima contracción diaria (MCD). En este trabajo se pretende analizar los posibles causantes que...

Maximum daily trunk shrinkage (MDS) is the most popular indicator derived from trunk diameter fluctuations in most fruit trees and has been reported to be one of the earliest signs in the detection of water stress. However, in some species such as olive trees (Olea europaea L.), MDS does not usually change in water stress conditions and trunk...

The influence of three irrigation treatments (T0, no stress; T1, soft stress; and, T2, moderate stress) on the key functional properties [fatty acids, sugar alcohols, organic acids, minerals, total polyphenols content (TPC), and antioxidant activity (AA)], sensory quality, and consumers' acceptance of table olives, cv. 'Manzanilla', was...

The purpose of this study was to assess the relationship between the effect of regulated deficit irrigation, cluster, developmental stages and two seasons (autumn 2015 and spring 2016) on the commercial and functional quality (carotenoids and plenolics levels) in 'Lazarino' and 'summerbrix' tomatoes. Autumn had a positive effect on the...

Olive trees (Olea europea L) are traditional Mediterranean specie. The agricultural management of olive orchards has been changed from 90's of the last century. The most important change is the great increase of the irrigation surface. This new water demand has been produced in water scarcity areas. Such conditions and the traditional...

The water needs for tomato crops are very high and could limit the viability of cultivation in semiarid environments. There is no agreement among works on irrigation regarding the sensibility of the flowering period. In addition, there is a lack of studies about the effects of water stress on fruit and cluster development under severe water...

En este vídeo se explica una técnica agronómica de programación de riego deficitario en base a medidas de estado hídrico en planta. El indicador que se usa es la variación del diámetro del tronco. Esta medida, basada en dendrometría, permite la monitorización continua y a distancia del cultivo. Permitiendo un ajuste del riego diario, basado en...

The continuous monitoring of water stress will increase the accuracy of the deficit irrigation scheduling. Almonds are very sensitive to water stress conditions and an important water consumer. Recently, a novel approach to the use of trunk growth rate (TGR) data has been proposed for olive trees. These works suggested the use of...

Endocarp development in olive trees includes three periods: growth (Period I), massive sclerification (Period II) and maximum hardening (Period III). The two first are strongly related to yield and irrigation management. Period I was reported to coincide with mesocarp cell division and thus with final fruit size. Period II was considered to be...
