Olive fly is the most dangerous pest in olive groves worldwide. Therefore the study of the most susceptible and resistant cultivars to olive fly can bring new information to diminish the olive flies harmful impacts. The main goal of the present study is to verify the olfactory response of olive fly to olive volatiles from five native Iranian cultivars (Fishomi, Mari, Rowghani, Shengeh, and Zard...

despite the profusion of flowers that develop on olive trees, only a few set fruit during the growing season and only about 1-2% of the fruit remains on the trees at maturity. therefore, to maximize fruit set and yield, it is important for growers to understand the cross-compatibility between cultivars when planning to establish an olive orchard. this study was carried out in shiraz, fars provi...

Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...

background: fatty acids are the main compounds in edible oils. oil thermal stability depends on the composition of fatty acids. so, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process.  methods: totally, eight virgin olive oil samples, including five imported oils from market place of mahabad an...

Olive leaf spot or peacock spot, caused by the fungal pathogen Spilocaea oleagina, can cause reduced growth and yield in olive trees (Olea eurapaea). Investigations were carried out during 20072010 to measure the prevalence and severity of olive leaf spot in the northern olive growing regions of Iran. The susceptibility of ten cultivars (Amygdalifolia, Blaidy, Koronakei, Mary, Manzanillo, Missi...

Blends of olive oils obtained from four cultivars ( Olea europaea L. cv. Chemlali, Chetoui, Oueslati and Koroneiki) were produced by two different methods blending: processing fruit mixtures or mixing monovarietal oils, using the same proportions selected cultivars. The blends biochemically characterized to evaluate quality, compared. results indicated that most successful formulations are main...

many factors, particularly the planted cultivar for oil production and climatic conditions, can affect olive oil quality. this research was conducted with 12 olive cultivars in olive research stations with different climatic conditions (taroum, roodbar, gorgan, kazeron and sarpolezehab). fruits with 4-4.5 ripening indices were harvested in each region. fatty acids composition data were analyzed...

Background: Fatty acids are the main compounds in edible oils. Oil thermal stability depends on the composition of fatty acids. So, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process.  Methods: Totally, eight virgin olive oil samples, including five imported oils from market place of Ma...

Virgin olive oil (VOO) is the only food product requiring official sensory analysis to be classified in commercial categories, in which the evaluation of the aroma plays a very important role. The selection of parents, with the aim of obtaining new cultivars with improved oil aroma, is of paramount importance in olive breeding programs. We have assessed the volatile fraction by headspace-solid-...
