Productive and vegetative behavior of olive cultivars in super high-density olive grove

Abstract

In recent years, there has been an increase in interest in super high-density (SHD) olive (Olea europaea L.) groves because they offer early entry into production, increased productivity and the possibility of using modified mechanical vine harvesters. This study was carried out in a young SHD olive grove to examine vegetative, histo-anatomical and productive characteristics and oil quality of the Spanish Arbequina and Italian Maurino and Leccino cultivars, characterized by low, low-to-medium and high vigor, respectively. Arbequina had low vigor and limited development in height and width, as well as a high leaf/wood ratio. Maurino had a canopy volume similar to that of Arbequina and, despite a great tendency to grow in height, had low vigor, a rather compact vegetative habitus, but good lighting in the canopy and high production efficiency. In Maurino, a greater palisade parenchyma height and a larger exposed lateral surface area of the palisade parenchyma cells were observed. In the fourth year after planting, fruit production of Arbequina was about 30 % less than Leccino and Maurino. The oil content on a dry weight basis was slightly higher in Arbequina and Maurino than in Leccino. Oil quality was good for all cultivars.

Effects of Nitrogen Foliar Fertilization on the Vegetative and Productive Performance of the Olive Tree and on Oil Quality

“…Pn was determined using a portable ADC LCA-3 gas exchange analyser (Analytical Development Company Ltd., Hoddesdon, UK) and a Parkinson-type assimilation chamber as described by [20]. After the gas exchange measurements, the leaves were immediately transferred to the laboratory in a portable refrigerator for determination of area dry mass (ADM) as described in [22].…”

Behavior of Four Olive Cultivars During Salt Stress

“…In this context it’s important to select cultivars that may give good performance when cultivated in soil with salinity problems or irrigated with saline water. Among the cultivars studied in the present work Arbequina and Koroneiki cultivars are the subject of increasing interest given their adaptability to super-intensive cultivation systems (Proietti et al, 2015). The identification of saline-resistant cultivars is of particular interest, especially for those cultivation systems, such as the super-intensive, which require large quantities of water as the availability of non-saline water will decrease dramatically in the future due to climate change.…”

Management of Light for Quality Production of Litchi

“…Feng et al (2013) concluded that the anthocyanin content in apple fruit exposed to sunlight was higher than in shaded fruit. Proietti et al (2015) found that in olive light distribution in the canopy changes in olive cultivars Arbequina, Leccino and Maurino and this could be one of the reasons for the higher production efficiency (amount of production per unit of leaf area) in Maurino compared to the other cultivars.…”
