High-resolution UAV imagery for field olive (Olea europaea L.) phenotyping
2021
Remote sensing techniques based on images acquired from unmanned aerial vehicles (UAVs) could represent an effective tool to speed up the data acquisition process in phenotyping trials and, consequently, to reduce the time and cost of the field work. In this study, we assessed the ability of a UAV equipped with RGB-NIR cameras in highlighting differences in geometrical and spectral canopy characteristics between eight olive cultivars planted at different planting distances in a hedgerow olive orchard. The relationships between measured and estimated canopy height, projected canopy area and canopy volume were linear regardless of the different cultivars and planting distances (RMSE of 0.12 m…
Water-saving techniques for restoring desertified lands: some lessons from the field
2022
Nature-based solutions can significantly contribute to restoration projects in areas affected by desertification processes, where they are necessary for reversing land degradation. Currently, one innovative solution is The Cocoon™, which has been designed as a new ecotechnology for improving seedling establishment. The Cocoon consists of a doughnut-shaped container made of recycled cardboard that provides water and shelter at least during the first year of a seedling, which is the most critical for plant establishment. To determine the effectiveness of this ecotechnology under different conditions, the Cocoon was tested on a variety of soils, climates, vegetation, and land uses. Six plantin…
Comportamento agronomico di quattro nuovi portinnesti ibridi pesco x mandorlo in un impianto ad alta densità in Sicilia
2009
The present study was aimed to evaluate the agronomic behavior of different rootstocks, recently licensed by the Dipartimento di Coltura e Difesa delle Specie Legnose of the University of Pisa, and tested in a high density planting system (2220 trees/ha). Trials were carried out in an experimental orchard established by the Dipartimento di Colture Arboree of the University of Palermo and located in Sicily (Sciacca – Agrigento – 150 m a.s.l.). The observations were carried out on clonal rootstocks: I.S. 5/8 (Polluce); I.S. 5/19 (Castore); I.S. 5/23; I.S. 5/29 and GF 677 grafted at dormant bud with the low chill requirement cultivar “Tropic Snow”. The orchard was established in 2004, trees we…
Phytophthora Root and Collar Rot of Paulownia, a New Disease for Europe
2021
Paulownia species are fast growing trees native to China, which are being grown in managed plantings in several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, and collapse, as a consequence of root and crown rot, were observed in around 40% of trees of a 2-year-old planting of Paulownia elongata × P. fortunei in Calabria (Southern Italy). Two species of Phytophthora were consistently recovered from roots, basal stem bark, and rhizosphere soil of symptomatic trees and were identified as Ph. nicotianae and Ph. palmivora on the basis of both morphological characteristics and phylogenetic analysis of rDNA ITS sequences. Koch’s postulates…
