The present study attempts to determine how some physiological and reproductive functions of olive tree (Olea europaea L., cv. Koroneiki) respond to enhanced UV-B radiation or heat. Enhanced UV-B radiation was applied to (1) three-year-old potted plants in an open nursery (corresponded to ca. 16% ozone depletion), and (2) in vitro cultured pollen samples(More)
Olive fruit fly Bactrocera oleae (Gmelin) (Diptera: Tephritidae) infestation levels were quantified in rainfed adult olive (Olea europaea L.) (Lamiales: Oleaceae) trees of seven cultivars originating from Spain, Italy, Greece, Portugal and France to determine their relationships with fruit length, width, weight, oil and mineral element content and to(More)
In the present study, four Greek (Agiorgitiko, Asyrtiko, Roditis and Xinomavro) and one international (Soultanina) grapevine cultivars (Vitis vinifera L.) were screened for their resistance to Phaeomoniella chlamydospora. Artificial inoculation was carried out by drilling a hole into the trunk and injecting a concentrated conidial suspension into the(More)
Self-fertility is largely decreased and even prevented by various mechanisms because, broadly, it causes inbreeding depression, although some species have retained self-reproduction regimes. Species of plants that display the self-incompatible sporophytic type of self-incompatibility may rarely self-pollinate. It is only possible in the absence of foreign(More)
