Gibberellic acid (GA3) increases berry size of "Emperatriz" seedless grape, the response depending on the phenological stage of vine at treatment date and on the concentration applied. From berry fruit set to 21 days later, 80 mg/L GA3 increased commercial berry weight by 50%-90%, depending on the year, reaching similar size to that of "Aledo"...

The olive tree is well adapted to the Mediterranean climate, however, the current increase in temperature as a consequence of the global warming affects the phenological stages and can accelerate the ripening of the fruits, moving the harvesting to periods that are less favorable for quality production. In this work, the impact of harvesting...

Old traditional cultivars are valuable genetic resources for crop improvement, but a great number of them have disappeared in the past century. This study aimed to characterize traditional cultivars of different Prunus species collected in small family orchards in southwestern Spain and to evaluate their genetic diversity and relationships....

BACKGROUND Mechanical harvesting with over-the-row harvesters in super-high-density (SHD) table olive orchards increases the effectiveness of fruit removal, although bruising can limit the fruit quality. Additionally, an early harvest in periods less favourable to quality production is increasingly frequent as a result of global warming. The...

At a time of increasing demand, the extremely high cost of manual labor required to harvest fruit in table olive groves is limiting the economic survival of the crop in many producing countries. New grove designs and management practices such as superhigh-density (SHD) groves now in use in oil olive production should be explored as an option to...

Iron deficiency induces a yellowing in the aerial part of plants, known as iron chlorosis, and reduces the growth, yield, and quality of the fruits. Understanding plant response to iron deficiency is essential for agronomic management. This study decoded the temporal response of tomato plants (Solanum lycopersicum L.) to iron deficiency by...

Las plantaciones superintensivas de olivar (Olea europaea L.), con densidades superiores a los 1.000 árboles por hectárea, se han convertido en una interesante alternativa al cultivo de olivar de almazara en la que el coste de recolección disminuye por la drástica reducción de la mano de obra y del tiempo requerido por el empleo de cosechadoras...

Sexual reproduction in olive is carried out for purposes such as breeding. The seedlings evolve from the juvenile to the adult stage, and until now, only the discrete developmental phases have been investigated in detail. However, the transition process has been poorly studied in fruit trees, especially in olive. In this paper, juvenile to...

Actualmente el sector del olivar en España incluye dos subsectores claramente diferenciados por su aprovechamiento: el olivar de almazara y el de mesa o verdeo, cada uno con unas particularidades específicas que los diferencian, tales como variedades empleada s y técnicas de cultivo como la poda o la recolección. En los últimos años, la...

Thirty-three new genotypes coming from a table olive cross-breeding program were evaluated to assess their adaptability to standard processes, namely Spanish-style and black ripe olives. Different physical and chemical parameters were evaluated in fresh fruits, processed olives and brines. Most of these traits exhibited large variability...

New super-high-density (SHD) olive orchards designed for mechanical harvesting using over-the-row harvesters are becoming increasingly common around the world. Some studies regarding olive SHD harvesting have focused on the effective removal of the olive fruits; however, the energy applied to the canopy by the harvesting machine that can result...

Airborne methodologies based on unmanned aerial vehicles (UAV) are becoming an extraordinary tool for implementing fast, accurate and affordable phenotyping strategies within plant breeding programs. The aim of this paper was to study the potential use of a previously developed UAV-OBIA platform, to fasten and support decision making for olive...

The need for the olive farm modernization have encouraged the research of more efficient crop management strategies through cross-breeding programs to release new olive cultivars more suitable for mechanization and use in intensive orchards, with high quality production and resistance to biotic and abiotic stresses. The advancement of breeding...

Las variedades locales de frutales seleccionadas a lo largo de los años por los agricultores, son muy interesantes para preservar la biodiversidad y los recursos fitogenéticos, ya que presentan unas características organolépticas peculiares y un valor cultural irremplazable. En 2007 se inició un trabajo de recuperación de variedades...
