abstract- olive (olea europaea l.) is one of the most valuable and widespread fruit trees in iran. salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (dakal, shiraz, zard and amigdalifolia) by emphasizing the correlation between measured parameters and ion (k+, na+) accumulation. plants were subjected to four s...

Fats are indispensable to life not only as an energy source but also for their structural role in the skin, retina, nervous system, lipoproteins, and biologic membranes. They are also precursors of important hormones and constitute the vehicle for the absorption of liposoluble vitamins. Nutritionists recommend a balanced lipid intake corresponding to a total amount of fats equal to 25% to 30% o...

The Mediterranean diet appears to be associated with a reduced risk of several chronic diseases including cancer and cardiovascular and Alzheimer's diseases. Olive products (mainly olive oil and table olives) are important components of the Mediterranean diet. Olives contain a range of phenolic compounds; these natural antioxidants may contribute to the prevention of these chronic conditions. C...

responses of plants to salinity stress and development of salt tolerance are extremely complex and various mechanisms appear to be involved. we employed a proteomic approach to study the mechanism of plant responses to salinity in a sensitive cultivar of barley (527 line). three-week-old seedlings were treated with 300 mm nacl for 3 weeks. total proteins of fourth leaf were extracted and separa...

The depletion of stratospheric ozone layer has led to the increase in solar ultraviolet (UV-B: 280-320 nm) radiation reaching the Earth’s surface and resulted in reduction of the growth and yield of crop plants. To defend against such adverse effect, plants may have developed some kind of resistance mechanism through differential expression of genes involved in UV stress. To determine the diffe...

Ayvalik is an important olive cultivar producing high quality oils in Turkey. In the present study, volatile and phenolic compositions of early-harvest extra virgin olive oil (cv. Ayvalik) were determined. The solvent-assisted flavor evaporation (SAFE) technique was used for the extraction of volatile components. The aromatic extract obtained by SAFE was representative of the olive oil odor. A ...

In this study, the effect of storage at different times and temperatures on in vitro olive pollen germination was investigated. Pollens Gemlik Domat cultivars GE119 GK138 genotypes were stored +4 °C, -20 -80 °C for 7, 35, 200, 365 days, respectively. status determined by petri agar method, choosing most suitable nutrient medium each olive. The media Gemlik, Domat, GE119, pollens 50 ml water + 1...

A survey in olive orchards Istria (Croatia) was carried out from 2016 to 2018 investigate pathogens potentially associated with decline and dieback. In nine orchards, canker-like symptoms were recorded on trunks branches. Six fungal species isolated cankers: Geosmithia sp., Diaporthe Diatrype stigma, Diplodia seriata, Neofusicoccum parvum, Pseudophaeomoniella oleae. Pathogenicity tests conducte...
