Olea europaea; alternate bearing; budbreak; climate; crops; cytokinins; flowering; fruit drop; fruit set; fruits; growers; income; inflorescences; oils; olives; pollination; spring; summer; trees; California
Abstract:
... Alternate bearing (AB), a low-yield “off” crop (OFF tree, OFF year) followed by a high-yield “on” crop (ON tree, ON year), is initiated in perennial tree crops by adverse climate events that occur during bloom or fruit set and affect not only the crop trees, but also the pollinizer trees, causing poor flowering, reduced pollination and fruit set, or excessive flower and fruit drop. The result is a ...

Abstract:
... Arthropods have great significance in integrated and ecological plant protection because the increase in their population can reduce the number of pests, thereby reducing the use of pesticides. It is necessary to maintain biodiversity within the cultivation area. Biodiversity is achieved by maintaining the ecological infrastructure that provides beneficial arthropods habitat, shelter and space for ...

Abstract:
... Current detection methods for contaminants in food use high-tech equipment sited in specialized laboratories. This makes online quality control along the food chain difficult. Official regulations limit pesticide and heavy-metal contamination, mainly for organic production, although their analysis is quite expensive, requires skilled personnel and is very difficult to apply to a large number of oi ...

Abstract:
... Olive anthracnose, a fungal disease caused by species of the genus Colletotrichum, is responsible for severe yield losses and poor oil quality. Typical symptoms appear in autumn or early winter, when the drupes begin to ripen. Under favorable conditions, symptoms on branches and leaves can also occur, leading to chlorosis, severe defoliation, and death of woody organs. Symptomless infection of flo ...

Abstract:
... The table olive (Olea europaea L.) is a widely produced olive product. Table olives are still harvested by hand. The low efficiency of hand harvesting and the rise in the costs of labor put this crop in a delicate situation. A selective abscission compound is considered crucial for the adoption of table olive mechanical harvesting. We studied the anatomical as well as the molecular differences bet ...

Abstract:
... Olea europaea produces small, white flowers, and its pollination strategy is generally considered anemophilous. However, this assumption does not fit with frequent observations of bees, and other members of the Hymenoptera, visiting the flowers and actively collecting the pollen. Pollen is frequently recorded in honey and pollen samples of the honey bee, Apis mellifera, but is often omitted when l ...
