Effects of zinc and boron foliar application on soluble carbohydrate and oil contents of three olive cultivars during fruit ripening

Influence of agroclimatic parameters on phenolic and volatile compounds of Chilean virgin olive oils and characterization based on geographical origin, cultivar and ripening stage

“…Camacho‐Cristobal et al demonstrated that boron deficiency increases phenol production. Furthermore, the combined action of boron and zinc enhances the quantity of phenolic compounds in olive fruits, particularly in semi‐arid areas …”

Potassium contributes to zinc stress tolerance in peach (Prunus persica) seedlings by enhancing photosynthesis and the antioxidant defense system

“…As an essential microelement involved in numerous physiological processes, trace amounts of Zn application contribute to fruit quality in particular Saadati et al, 2013). However, excessive amounts of Zn can lead to toxicity symptoms in plants.…”

“…Yet, zinc (Zn) sprays at critical periods can improve the fruit quality of apple trees , and foliar application of Zn contributes to soluble carbohydrate and oil contents in olive cultivars during fruit ripening (Saadati et al, 2013). However, due to its high mobility and bioavailability, Zn is considered to be a major industrial pollutant of both the terrestrial and aquatic environments (Barak and Helmke, 1993;Morillo et al, 2004).…”

Mycorrhizal, nutritional and virgin olive oil parameters affected by groundcovers

“…() who reported that phytosanitary copper application decreased total phenols in olive leaves, hence reducing their antioxidant properties. By contrast, boron foliar fertilization promoted phenol content of olive fruits, which was attributed to the role of boron in the metabolism of phenolic compounds ( Saadati et al., ). With regard to Sr, this element has been shown to be related to the accumulation of Ca and S in plants grown in soils with gypsum in Australia ( Reid et al., ), but further investigation is required to elucidate the relationships found here.…”
