3D image acquisition system based on shape from focus technique
2013
agent Agrosup Dijon de l'UMREcolDurGEAPSI; This paper describes the design of a 3D image acquisition system dedicated to natural complex scenes composed of randomly distributed objects with spatial discontinuities. In agronomic sciences, the 3D acquisition of natural scene is difficult due to the complex nature of the scenes. Our system is based on the Shape from Focus technique initially used in the microscopic domain. We propose to adapt this technique to the macroscopic domain and we detail the system as well as the image processing used to perform such technique. The Shape from Focus technique is a monocular and passive 3D acquisition method that resolves the occlusion problem affecting…
A study of thyme germplasm in Sicily
2009
hyme is characteristic of the Mediterranean and is of interest for its multifunctional nature. It is widely used in seasoning and flavouring, in herbal products and cosmetics. The versatility of this species means it is also useful in the protection of areas prone to erosion or an ornamental plant when designing low-maintenance gardens. Thyme germplasm constitutes a large part of the wild flora in Sicily and is a potentially useful source of genetic variability. On the basis of this, in the two-year period from 2004-2005, research was carried out on wild thyme accessions. These were used to evaluate both its productivity and individual biotypes with the functional characteristics most sough…
Genetic diversity of early ripening breba accessions (Ficus caricaL.) found in the “Pomona” Apulian collection
2017
In order to study fig (Ficus carica L.) biodiversity in Southern Italy, a study was performed in a private Apulian collection, "I Giardini di Pomona", in which 350 different native and international cultivars were recovered in the last 15 years. This collection is located in middle part of Apulia region inside an area of great charm called "Valle D'Itria". In the region, fig is an important edible fruit tree species and it has been used for fresh fruit production, for centuries. Moreover, fig is considered as an important element of natural landscape and as significant cultural heritage. In this study, the Apulian breba cultivars, characterized by interesting agronomic traits, such as early…
TWO YEARS OF STUDIES INTO NATIVE BERMUDAGRASS (CYNODON SPP.) GERMPLASM FROM SICILY (ITALY) FOR THE CONSTITUTION OF TURF CULTIVARS
2008
Bermudagrass (Cynodon spp.) is the most widely used warm season turf species in the world for sport, lawn and utility turfs. The species is widespread in Sicily (Italy) where it exhibits a large range of diverse morphological characteristics due to a long process of adaptation to varying climatic and soil conditions of the island. In order to exploit the bermudagrass genetic resources and establish a germplasm bank for use in various plant breeding programmes, bio-agronomic evaluation tests were carried out on the 40 Sicilian biotypes of Cynodon spp. from 2002 to 2004 at the experimental farm “Orleans”, University of Palermo. The accessions were compared to the standard cultivar ‘Savannah’,…
Rovello bianco, caratterizzazione di un vitigno autoctono campano.
2009
Il “Rovello bianco”, conosciuto localmente come “Greco muscio” nuovo vitigno autoctono campano è stato oggetto di uno studio triennale (2004-2005) considerando il “Fiano” come varietà di riferimento. L’analisi molecolare mediante marcatori micro satelliti (SSR) ne ha stabilito l’unicità del profilo genetico. La valutazione agronomica è stata ottenuta attraverso annuali e sistematici rilievi, effettuati su 50 piante di 5 anni di età, registrando da parte del “Rovello bianco” un più basso vigore vegetativo rispetto al “Fiano” e una buona resistenza alle più diffuse fitopatie. Ben distinta dal vino “Fiano” è risultata invece la componente organica volatile. Principalmente alcoli isoamilici qua…
Using Anther Culture Method for Flax Breeding Intensification
2015
Flax breeding is a long and complicated process based on hybridization and following selection of the best plants. Because of possible occasional cross-pollination the development of genetically stable homozygous lines could last more than 15 years. For more rapid creating of initial material for flax breeding anther culture methods for producing doubled haploid (DH) lines could be used successfully. The goal of this study was to develop the best anther culture protocol for producing DH lines from hybrids included in Latvian flax breeding programme and to do preliminary field evaluation of obtained DH lines. F4 hybrids were used in the experiment. Method, most applicable for establishing of…

Agronomic evaluation and quality characterization of lentil accessions (Lens culinaris L.) in a Mediterranean environment
2013
Agronomic evaluation and quality characterization of lentil accessions (Lens culinaris L.) in a Mediterranean environmentLentil (Lens culinaris Medik.) is an important grain legume cultivated in the Mediterranean region and used for human nutrition. An extensive differentiation of lentil over millennia has permitted the evolution of many landraces. These ecotypes often are the result of centuries of selective choices by local farmers and are characterized by high genetic variability and high adaptation to different environmental conditions. Presently, lentil is mainly cultivated in marginal areas of Central and Southern Italy and in Sicily small cultivation has permitted the evolution of lo…
