olive (olea europaea l.) consumption and production are socially and economically important in iran. the aim of this experiment was to evaluate the vegetative characteristics, floral biology, fruit characteristics, oil percentage, and yield of eleven olive cvs. (‘arbequina’, ‘amygdalolia’, ‘bledy’, ‘roghani’, ‘zard’, ‘sevillana’, ‘koroneiki’, ‘conservalia’, ‘gordal sevillana’, ‘manzanilla’, and...

Olive anthracnose, caused by Colletotrichum, is an important disease in olive-growing regions, with the most destructive symptoms being fruit rot and blossom blight. Susceptibility of to Colletotrichum increases maturity, but differences between cultivars species have been reported, still information on flower susceptibility during development scarce. The olive Arbequina, Coratina, Frantoio Pic...

Changes in the plant water status, biochemical and hormonal responses, were investigated three olive cultivars (Arbequina, Arbosana Chetoui) grown a super-high-density orchard under partial root-zone drying (PRD) irrigation. Four irrigation treatments applied during two growing seasons (2015 2016); control treatment (100 % ETc) irrigated at 100 of crop evapotranspiration on both parts PRD PRD, ...

Anthracnose of olive (Olea europaea ssp. europaea L.), caused by Colletotrichum species, is a serious disease causing fruit rot and branch dieback, whose epidemics are highly dependent on cultivar susceptibility and environmental conditions. Over a period of 10 years, there have been three severe epidemics in Andalusia (southern Spain) that allowed us to complete the assessment of the World Oli...

The dynamics of maturation index, water and oil concentrations, total phenols in olive fruit, together with fatty acids content oil, was studied as a function time after flowering for super-high-density ‘Arbequina’, ‘Arbosana’ ‘Koroneiki’ using data collected three seasons. Oil concentration increased linearly from the middle August until reaching plateau by end November all cultivars, (45.7 g/...

The olive tree (Olea europaea L.) is a species of great importance in history and economic, with large phenotypic variability, represented through wide range cultivars spread throughout the world. There are several studies on characterization number species. However, there need to uncover how these traits heritable, they can change when environmental conditions vary. For this reason, objective ...

One of the challenge fruit growers are facing is to balance between tree production and vegetative growth from year to year. To investigate the existence of genetic determinism for reproductive behaviour in olive tree, we studied an olive segregating population derived from a cross between 'Olivière' and 'Arbequina' cultivars. Our strategy was based on (i) an annual assessment of individual tre...
