Quantification of dwarfing effect of different rootstocks in ‘Picual’ olive cultivar using UAV-photogrammetry

Abstract Hedgerow orchard is an olive growing system where trees are planted at a super high-density higher than 20-fold (i.e., 1200–2500 ha −1 ) compared to the traditional density of orchards (usually 50 160 ). It dominating great proportion new plantations because harvesting can be fully mechanized, it early bearing and has relatively constant high productivity. However, there limited number cultivars with sufficiently low vigour suitable for such plantation densities. For that reason, set breeding selections been used in field experiment as rootstocks reducing “Picual”, most frequent cultivar Spain. Tree was characterized by measuring crown height, projected side areas, volume through analysis photogrammetric point clouds created from images acquired unmanned aerial vehicle. A significant reduction ‘Picual’ observed tested, canopy reduced up one half. High variability on vigour, first their relative relationship between different used. This indicates might enough genetic perform selection dwarfing cultivar.
