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 ...

The aim of this work was to generate a high resolution temporal mapping of the biosynthetic pathway of vitamin E in olive fruit (Olea europaea cv. "Koroneiki") during 17 successive on-tree developmental stages. Fruit material was collected from the middle of June until the end of January, corresponding to 6-38 weeks after flowering (WAF). Results revealed a variable gene regulation pattern amon...

one of the problems in growing olive trees is pollen-incompatibility. this study was conducted in gorgan climatic condition to determine the self-incompatibility of olive cv koroneiki and to select the suitable pollenizers. randomized complete block design with three replication (trees) and six treatments including open pollination, self pollination, mission, conservalia, sevilana and valanolia...

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...

Extra virgin olive oil (EVOO) is highly appreciated by consumers for its unique sensory characteristics that are directly related to volatile composition. The objective of this study was investigate the effect cultivar and geographical origin on composition Greek monovarietal EVOOs. Samples three local cultivars (Koroneiki, Kolovi Adramytini) originating from areas Greece (Crete, Lesvos Pelopon...

in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

Olive oil phenolic fraction considerably contributes to the sensory quality and nutritional value of this foodstuff. Herein, the phenolic fraction of 203 olive oil samples extracted from fruits of four autochthonous Moroccan cultivars ("Picholine Marocaine", "Dahbia", "Haouzia" and "Menara"), and nine Mediterranean varieties recently introduced in Morocco ("Arbequina", "Arbosana", "Cornicabra",...

The current study was designed to assess the comparative morphology of eight olive cultivars with different geographical origins and diverse genetic backgrounds, introduced a new climatic zone. morphological parameters (five exotic three domestic) (Bari Zaitoon-1, Bari Zaitoon-2, Favolosa (FS-17), Koroneiki, Balkasar, Ottobratica, Leccino, Arbequina) were compared at experimental area Departmen...

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...
