Abstract:

Notwithstanding a still widespread and considerable weight of traditional olive groves throughout Italy, there is large interest in investing in new plantations, different both for cultivars and agronomic approaches, and to renew at least partially the olive-oil heritage. Furthermore, Italy is one of the main importing countries in the world of oil and table olives. To match the internal demand and boost olive-oil production, the National Olive Plan suggests adopting modern high-density plantations like other EU Countries (e.g., Spain). Traditional groves are partly replaced by high-density ol

Abstract:

Aim. To analyze the scientific and technical literature, to identify trends and prospects for world production of olives. Discussion. Olive is one of the most cultivated fruit crops in the world. It surpasses the main fruit crops in the area of cultivation: apple, pear, peach and nectarine, apricot and orange, and is second only to coffee. In the period from 1994 to 2017 a significant tendency of increasing this value from 7.66 to 10.8 million hectares was noted. In addition, world fruit production is steadily growing from 11.47 million tons (in 1994) to 20.87 million tons (in 2017). The main

Abstract:

In vitro and animal studies show that polyphenols from olives have potent antioxidant activities; 50 % of the phenolic compounds contained in olives and virgin olive oil are hydroxytyrosol and derivatives thereof. Hydroxytyrosol is the major olive polyphenol consumed and well absorbed in humans. It is considered to have the highest antioxidant potency compared to the other olive polyphenols. Review of the human intervention studies showed that olive polyphenols decreased the levels of oxidized-LDL in plasma and positively affected several biomarkers of oxidative damage.

Abstract:

The true origin of the olive is not known but is speculated to be Syria or possibly sub-Saharan Africa. For more than 6000 years, the cultivated olive has developed alongside Mediterranean civilizations and is now commercially produced on more than 23 million acres (9.4 million ha) in the Mediterranean basin. New plantings also exist in California, Chile, Argentina, South Africa, and Australia. Various nonscientific selection processes created a multitude of different cultivars.

The relationship between agriculture and climate change is gaining prominence year by year in due to both adaptation and mitigation issues, because agriculture contributes to carbon emissions and acts as a carbon sink.

Only certain traditional cultivars are well suited for these new olive plantations. The new orchards therefore require new cultivars.

Abstract:

Olive production in the first few years after planting depends on how the canopy covers the hedgerow and develops flowers. Therefore, optimum irrigation management should look for the minimum amount of water required for maximum growth and bud initiation. The response of a young hedgerow olive orchard to different irrigation strategies was recorded for 3 years after planting in 2003. Observations included stem water potential (Ψstem), leaf conductance (gl), shoot and trunk growth, canopy development, and flowering. During the first year, olives received 74 mm of irrigation. During the second a

Abstract:

The family Braconidae consists mostly of specialized parasitoids, some of which hold potential in biocontrol of agricultural pests. Psyttalia concolor, Psyttalia humilis and Psyttalia lounsburyi are parasitoids associated with Bactrocera oleae, a major pest of cultivated olives. The native range of Psyttalia concolor is the Mediterranean, and P. humilis and P. lounsburyi are native to sub-Saharan Africa. This study reports the mitochondrial genomes of the three species, thus laying the foundation for mitogenomic analyses in the genus Psyttalia. Comparative mitogenomics within Braconidae showed

A comparative study was conducted to evaluate the influence of seven different levels of irrigation applied to `Arbequina I-18' olive (Olea europaea L.) trees grown in a super-high-density orchard (1,656 trees/ha) in the Sacramento Valley of California. Water was applied differentially by drip irrigation at rates of 15%, 25%, 40%, 57%, 71%, 89%, and 107% evapotranspiration (ETc) in 2002, and 28%, 33%, 55%, 74%, 93%, 117%, and 140% ETc in 2003.

Ring nematodes are obligate ectoparasites on cultivated and wild herbaceous and woody plants, inhabiting many types of soil, but particularly sandy soils. This study explored the morphometrical and molecular diversity of ring nematodes resembling Criconema annuliferum in 222 soil samples from fruit crops in Spain, including almond, apricot, peach and plum, as well as populations from cultivated and wild olives, and common yew. Ring nematodes of the genus Criconema were detected in 12 samples from under Prunus spp. (5.5%), showing a low to moderate nematode soil densities in several localities

Abstract:

Cross-tolerance to abiotic stresses is a typical phenomenon in plants which occurs when exposure to one form of stress confers tolerance to a variety of stresses. Our study aims at investigating whether salinity priming could induce, after a recovery period (2 months), drought tolerance in olive cv. Chétoui. Here, our results revealed that this method of cross-adaptation had further enhanced the olive’s subsequent response to drought. In fact, relative to the non-pretreated plants, the salt-pretreated ones displayed an enhancement in terms of shoot biomass accumulation, photosynthetic performa
