Crocus sativus L. Ecotypes from Mediterranean Countries: Phenological, Morpho-Productive, Qualitative and Genetic Traits
2021
The characterization of C. sativus ecotypes is of great interest for preserving them from a possible genetic erosion due to the decrease of European cultivation surface. In this study, we evaluated four ecotypes from Italy (Sardinia and Abruzzo), Spain (Castilla-La Mancha), and Greece (Kozani) in order to detect the existence of variability and promote the biodiversity of this crop. Thirty-one traits related to saffron flowering, flower morphology, production of spice and daughter corms, vegetative development (leaf and corm traits), and spice quality, were evaluated. In addition, a genetic analysis through three PCR-based approaches, SSRs, RAPD, and SRAP was assessed. Results highlighted a…
Effects of environment and sowing time on growth and yield of upland cotton (Gossypium hirsutum L.) cultivars in Sicily (Italy)
2020
Cotton is one of the most important industrial crops in the world. Though widely cultivated in Sicily (Italy) in the past, cotton growth on the island has disappeared today due to a complex variety of agronomic, economic and socio-political reasons. In recent years, increased interest in natural fibers worldwide has led to a revival in cotton plants in the Mediterranean area. The aim of this paper was to assess the response of Gossypium hirsutum L. cultivars to different environments and sowing times. Elsa and Juncal were selected from the most promising cotton cultivars regarding earliness and productivity. Plants were tested with three sowing times and in two Sicilian environments. Cotton…
EARLINET observations of the 14-22-may long-range dust transport event during SAMUM 2006: validation of results from dust transport modelling
2009
We observed a long-range transport event of mineral dust from North Africa to South Europe during the Saharan Mineral Dust Experiment (SAMUM) 2006. Geometrical and optical properties of that dust plume were determined with Sun photometer of the Aerosol Robotic Network (AERONET) and Raman lidar near the North African source region, and with Sun photometers of AERONET and lidars of the European Aerosol Research Lidar Network (EARLINET) in the far field in Europe. Extinction-to-backscatter ratios of the dust plume over Morocco and Southern Europe do not differ. Ångstr¨om exponents increase with distance from Morocco. We simulated the transport, and geometrical and optical properties of the dus…
EFFECTS OF PLASTIC MULCH AND FLOATING COVER ON LETTUCE PRODUCTION IN SICILY
2012
The use of floating cover directly applied on top of the crop is rapidly increasing on leafy vegetables like lettuce as a simple, inexpensive and effective technique to induce earliness. Two lettuce types, ‘Iceberg’ and ‘Romaine’, under two different crop management systems (black plastic mulch and black plastic mulch combined with floating cover) were tested in Sicily in 2007. Plug type transplants were planted at the end of January on double rows. The nonwoven floating cover was applied after transplanting. Maximum and minimum air temperatures below the floating cover during the growing period were in the average 5 and 1.5°C higher than those without cover. Lettuces mulched and protected …
Effects of plant type on two strawberry cultivars in Sicily
2014
In Sicily fresh plants have for years been replacing the once popular cold-stored ones. Good early cropping is the aim of all strawberry growers in the island’s Marsala district. The present trial tested the response of the new strawberry cultivars ‘Sabrosa’ and ‘Florida Fortuna’ using fresh plug and bare-root plants. ‘Florida Fortuna’ plug-plants turned out to be the most promising type as a cash crop in delivering extra early ripening.
EFFECTS OF PRE-PLANT SOIL TREATMENTS ON STRAWBERRY IN SICILY
2014
The 2005 ban by Italy of methyl bromide (MB) has resulted in significant crop management difficulties in pre-plant soil dis-infestation. We report two pre-plant soil treatment techniques and their effects on the performance of new cultivars and selections tolerant to the main root pathogens. The plants grown in soil treated with chloropicrin + 1,3 dichloropropene were the most productive. While neither treatment affected average berry weight, soluble solids content or titratable acidity, the treatment × cultivar interaction was significant and fruits from plants grown in treated soil were firmer than control s. Selection PA 260 and cultivar Florida Fortuna were the earliest, three selection…
Minimizing weighted earliness-tardiness on parallel machines using hybrid metaheuristics
2015
We consider the problem of scheduling a set of jobs on a set of identical parallel machines where the objective is to minimize the total weighted earliness and tardiness penalties with respect to a common due date. We propose a hybrid heuristic algorithm for constructing good solutions, combining priority rules for assigning jobs to machines and a local search with exact procedures for solving the one-machine subproblems. These solutions are then used in two metaheuristic frameworks, Path Relinking and Scatter Search, to obtain high quality solutions for the problem. The algorithms are tested on a large number of test instances to assess the efficiency of the proposed strategies. The result…

UPDATE ON THE SICILIAN STRAWBERRY BREEDING PROJECT
2014
The strawberry industry in Sicily differs from that of Italy’s other southern regions since the particularly warm winter weather results in earlier fruit ripening. Cultivar choice is thus of key importance for the success of Sicily’s strawberry industry. The old cultivar Tudla®Milsei has recently been replaced by cultivars ‘Florida Fortuna’, ‘Florida Festival’, ‘Sabrosa®Candonga’, ‘Naiad®Civl35’ and ‘Nora’ developed by both public and private breeding programs in Florida, Spain and Italy. The strawberry breeding program in Sicily started about 20 years ago in an effort to develop new cultivars well adapted to an area of very low winter chilling, with requirements featuring superior performa…
Effetto della posizione degli ovoli sulla produttività del carciofo spinoso di sicilia
2010
In Sicily, the Spinoso di Sicilia artichoke is appreciated at regional level for its organoleptic characteristics, but in recent years, its cultivation area has been subject to a progressive reduction because of its susceptibility at the atrophy of head, low earliness, low productivity, and lack of uniformity of the productions. These problems are due to genetic variability, diseases and disforme propagation material (ovoli). This study was conducted to evaluate the influence of the ovoli position (apical, median and basal) in the rhizome of mother plants on morpho-phisiological and productive aspects of the artichokes. The results showed that basal ovoli gave faster growth, better plant co…
