The purpose of this study was to extract phenolic compounds from olive leaves of Koroneiki, Roghani and Mission varieties by maceration and Microwave-assisted extraction (MAE) methods with different solvents. Our results revealed that the extraction method, solvent and variety had a significant effect on the amount of phenolic compounds (p<0.05). In both extraction methods, Koroneiki and Missio...

There is an ancient and prodigious history of olive trees because of their nutritional, medicinal, and traditional uses. Intensive studies have been conducted on olive leaves because they have many positive and beneficial effects for human health. In this study, different solvents were used to examine the olive leaves for their antioxidant and antimicrobial activities and their possible food ap...

Inoculating olive plantlets with the arbuscular mycorrhizal fungi (AMF) Glomus mosseae, Glomus intraradices or Glomus claroideum increased plant growth and the ability to acquire nitrogen, phosphorus, and potassium from non-saline as well as saline media. AMF-colonized plants also increased in survival rate after transplant. Osmotic stress caused by NaCl supply reduced stem diameter, number of ...

Accurate crown characterization of large isolated olive trees is vital for adjusting spray doses in three-dimensional crop agriculture. Among the many methodologies available, laser sensors have proved to be the most reliable and accurate. However, their operation is time consuming and requires specialist knowledge and so a simpler crown characterization method is required. To this end, three m...

Germplasm collections of tree crop species represent fundamental tools for conservation of diversity and key steps for its characterization and evaluation. For the olive tree, several collections were created all over the world, but only few of them have been fully characterized and molecularly identified. The olive collection of Perugia University (UNIPG), established in the years' 60, represe...

To begin, the methodology followed to reconstruct the origin and history of the olive is presented. The genetic structure (density of alleles across the geographic distribution of individuals) based on allele frequencies of the present oleaster tree in the Mediterranean Basin computed with different methods of comparison with the genetic structure of cultivars grouped based on their geographic ...

Under certain conditions, olive trees grown on calcareous soils suffer from iron chlorosis. In the present study several olive varieties and scion-rootstock combinations were evaluated for their tolerance to iron chlorosis. Plants were grown over several months in pots with a calcareous soil, under two fertilization treatments. These consisted of periodic applications of nutrient solutions cont...

Agroforestry systems can be an effective means of stabilizing or even enhancing crop yields under climate change. Although trees compete with crops for soil resources in agroforestry,they also improve crops' growing conditions, especially, by providing shade drought. They promote higher and harvest quality the drylands. However, beneficial effect tree may depend on seasonal pattern rainfall, wh...

Olive trees, which are planted widely in China, economically significant. Timely and accurate acquisition of olive tree crown information is vital monitoring growth accurately predicting its fruit yield. The advent unmanned aerial vehicles (UAVs) deep learning (DL) provides an opportunity for rapid parameters the crown. In this study, we propose a method automatically extracting (crown number a...

The chemical composition and radical-scavenging activity of wood samples from 10 main Spanish olive cultivars were studied. The wood samples were collected during the pruning works from trees growing under the same agronomical and environmental conditions. The 10 ethyl acetate extracts were submitted to HPLC-DAD/ESI-MS analysis to determine the phenolic constituents. Seventeen compounds were id...
