We studied the self-incompatibility of two main Spanish olive ( Olea europaea L.) cultivars, `Picual' and `Arbequina', by testing selfing seeds with microsatellites. For this purpose, we used a rapid single-seed DNA extraction method four highly polymorphic analyzed produced in branches bagged for from mono- multi-cultivar orchards 2002 2003. did not find any seed coming branches, either cultivar, types orchards. Additionally, tested free pollination mono-cultivar different locations. In...

The need for the olive farm modernization have encouraged research of more efficient crop management strategies through cross-breeding programs to release new cultivars suitable mechanization and use in intensive orchards, with high quality production resistance biotic abiotic stresses. advancement breeding are hampered by lack phenotyping methods quickly accurately acquire traits such as morphological attributes (tree vigor vegetative growth habits), which key identify desirable genotypes...

At a time of increasing demand, the extremely high cost manual labor required to harvest fruit in table olive groves is limiting economic survival crop many producing countries. New grove designs and management practices such as superhigh-density (SHD) now use oil production should be explored an option facilitate mechanical harvesting olives. The feasibility two cultivars, Manzanilla de Sevilla Cacereña, harvested 5-year-old SHD (1975 trees/ha) was studied 2012 when trees both cultivars...

While stigma anatomy is well documented for a good number of species, little information available on the acquisition and cessation stigmatic receptivity. The aim this work to characterize development receptivity, from anthesis degeneration, in pentacarpellar pear ( Pyrus communis ) flower. Stigma receptivity were monitored over two consecutive years, as capacity stigmas offer support pollen germination tube growth. In an experiment where hand pollinations delayed specified times after...

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 SHD have focused on effective removal of fruits; however, energy applied to canopy by machine that can result in fruit damage, structural damage or extra stress trees has been little studied. Using conventional analyses, this study investigates effects different nominal speeds and beating frequencies efficiency...

Abstract Super-high density olive orchards may increase profitability for table producers. However, water needs and fruit damage could limit their viability. Deficit irrigation scheduling would reduce the amount of required, but rehydration before harvest is extremely important. The aim this work was to compare a typical deficit farm management model with regulated one based on plant status. experiment carried out during three seasons in years-old (4 × 1.5 m) commercial orchard. In both...

The relationship between the length of juvenile period and nine olive seedling parameters (plant height, diameter, number nodes, lateral shoots, internode length, leaf width, area, shape index) was explored in 287 plants belonging to four different progeny. traits were measured at two timepoints: after had completed a forced growth cycle greenhouse/shadehouse (15 months sowing) one growing season field (27 sowing). Strong linear tendencies most vigour (mainly plant height diameter) with time...

Previous analyses of olive ( Olea europaea L.) crosses have revealed an important degree pollen contamination. For this reason, the authors tested paternity a set progenies coming from among different cultivars within breeding program Córdoba, Spain, using four polymorphic microsatellites. They found that expected sired 141 (83.4%) 169 samples analyzed. The contamination rate was either almost total or null each particular cross considered, not being comparable between crosses. In second...

The cultivar Oblonga may have originated from a volunteer seedling at an orchard near Corning, Calif., about 1940. Its main virtue is its high degree of resistance to Verticillium dahliae. `Frantoio' the variety in Italy and has been planted worldwide because content top-quality oil. In present study, we show that both cultivars same fifteen morphological eight agronomical traits amplified patterns for 22 RAPD primers five SSRs. This indicates `Oblonga' are probably cultivar.

Apples and pears are fruit crops particularly susceptible to cropping irregularities. A strong relationship has been observed between the effective pollination period (EPP) general of orchard. The EPP concept also proven be a useful parameter establish variation in reproductive process behaviors. For apples pears, slow pollen tube growth shown main limiting factor traditional cooler temperate cultivation regions. However, while higher temperatures speed up growth, expansion these into warmer...

AbstractSUMMARYWe examined growth and development of the 'Manzanilla' olive fruit mesocarp in transverse equatorial sections during first 12 weeks after full bloom (AFB). Sequential sampling quantitative data provided an integrated view formation this tissue. The mesocarp, or flesh, was formed by relatively isodiametric parenchyma cells with a small number isolated sclereids. By four AFB gradient cell size characteristic mature fruits began to appear. Biweekly measurements indicated that, as...

Summary New table olive genotypes (48) coming from a cross‐breeding programme were evaluated. Most of the fruit traits covered wide range variability on set genotypes, weight (1.1–9.7 g), pulp‐to‐pit ratio (1.7–10.0), shape (1.0–1.6) and oil content (1.3–15.2%). This is first time that healthy compounds such as triterpenic acids phenolic have also been evaluated in progenies. Genotypes stored for 2 months sterilised brine (5% NaCl 0.5% acetic acid). A high amount maslinic (685.0–1394.2 mg kg...
