Oleuropein, Hydroxytyrosol and Tyrosol are three major phenolic compounds present in olive with remarkable pharmacological effects. In this study, leaves and fruit of four olive cultivars including ‘Fishomi’, ‘Mary’, ‘Roghani’ and ‘Zard’ grown in the north of Iran were collected for comparative evaluation of the concentration of Oleuropein, Hydroxytyrosol and Tyrosol as well as antioxidant prop...

In the present study, bio-meteorological models for predicting olive-crop production in the southern Iberian Peninsula were developed. These covered a 16-year period: 1994-2009. The forecasting models were constructed using the partial least-squares regression method, taking the annual olive yield as the dependent variable, and both aerobiological and meteorological parameters as the independen...

Agronomic practices can modify olive fruit and oil quality. However, there is little information on the influence of fertigation, a common practice in most intensive orchards. We studied nutrient distribution in the soil profile following fertigation with different doses of N-P-K fertilizer, and its effect on nutrient concentrations, yield and both table olive and oil quality. Measurements were...

Developing Berberis hispanica Boiss & Reuter berries are heavily attacked by a single species of fly larvae which feed on seed contents. There is a steady increase in fruit attack incidence with increasing number of seeds in the fruit, and individual developing seeds have a greater average probability of escaping predation when single in fruits (0.688) than when two (0.379) or more (0.120) are ...

for many years, assessment of olive oil quality and itsauthenticity confimation has been of great importanceto guarantee olive oil safety in compliance with legislations. these include the investigation of olive oil purityand quality by analyzing several parameters such as fattyacid composition, sterols, phenolic compounds, triacylglycerol and etc, through performing conventional andadvanced hy...

thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...
