MANAGING SUBTERRANEAN CLOVER, ANNUAL MEDIC AND VETCH FOR SICILIAN VINEYARD SUSTAINABILITY
2004
During 2005/2006 a vineyards, located in south-west of Sicily (37° 60’ N – 12° 30 E), were subjected to five different soil managements: “conventional” ( T ) soil management using up to eight soil plowing with a five furrow plow; natural cover cropping ( N ), vetch cover cropping ( V ) (Vicia sativa L.); subclover cover cropping ( S ) (trifolium subterraneum var. Clare); medic cover cropping ( M ) (medicago polymorpha var. Santiago). In the layer 0-25 cm, soil moisture, total N, NO3, NH4, and soil organic matter were determined. Fresh and dry biomass weight, and total nitrogen percentage were determined on nine one square meter subplots for each thesis. Soil erosion was measured, using a Ge…

Specifics of pesticides effects on the phytopathogenic bacteria
2016
The data concerning the effects of pesticides of different nature on the phytopathogenic bacteria was examined and summarized. Without extensive research on the mechanisms of interaction between pathogenic bacteria and pesticides in the literature review a similar message about microorganisms of soil and phyllosphere are included. The bacteria can be suppressed permanently by pesticides with a mechanism of action that universally affects biological processes in living systems. Long-term storage, ease of use and fast visible effect are the ad vantages of synthetic pest ic ides remed ies. But chemica l po llution, shifts in the ba lance of ecosystems, unpredictable effects of chemical pestici…
Assessment of available potential of agro - biomass and energy crops phytomass for biofuel production in Ukraine
2017
Przedstawiono analizę publikacji wyświetlających problem wykorzystania biomasy jako odnawialnego źródła energii na Ukrainie. Wykorzystanie biomasy w systemie paliwowo -energetycznym kraju jest bardzo ważnym zadaniem. Celem badań była ocena dostępnego potencjału biomasy rolnej oraz fitomasy z upraw energetycznych do produkcji biopaliwa. Przedstawiono technikę oceny, określono potencjał i obliczono efektywność energetyczną wykorzystania biomasy na Ukrainie. Udowodniono, że wykorzystanie biomasy rolniczej do celów energetycznych w Ukrainie pozwala zmniejszyć zależność energetyczną kraju od nieodnawialnych źródeł energii.

In vitroplant regeneration and gene transfer in the wild tomatoLycopersicon cheesmanii
2001
SummaryThis paper reports on protocols for in vitro plant regeneration, gene transfer and on shoot salt tolerance from two accessions of L. cheesmanii (Riley). Shoot organogenesis was achieved on media with zeatin or BA/IAA combinations. The two accessions tested, LA1401 and LA530, showed differences in both their aptitude to regenerate and their salt tolerance in vitro. The accession LA530 had a higher organogenic potential than LA1401 (97% vs. 80% of organogenic explants). In contrast, none of the LA530 isolated shoots rooted when cultured in full strength MS-modified medium supplemented with 200.mM NaCl while 93% of shoots from LA1401 formed roots. Finally, Agrobacterium-mediated transfo…
Sulla (Hedysarum coronarium L.) leaves and stems as a potential biofuel feedstock
2014
Sulla (Hedysarum coronarium L. syn., Sulla coronaria [L.] Medik.) is a short-lived perennial legume native to the Mediterranean basin, where it is extensively grown as a 2-year forage crop playing a key role in cereal-based systems of semi-arid regions thanks to its versatility, (e.g., used for grazing, hay and silage production, and grazing associated with hay production), good-quality forage, and environmental benefits. To date, sulla has not been considered as a bioenergy crop. This research aimed to evaluate the potential of sulla biomass as a biofuel feedstock; in addition, due to the possibility to separate the leaves from the stems as suggested for alfalfa, the biomass composition wa…
Plant landscape and phytodiversity in the archeological area of Segesta (NW Sicily)
2018
In the system of Sicilian archaeological parks, the area of Segesta - an ancient city of western Sicily referring to the Carthaginian eparchy, - represents, together with Selinunte, Erice and Mothia, another integrated hotspot of biodiversity and archeaology. The current plant landscape is strongly influenced by a millenary anthropic transformation. There are no residual expressions of the original plant covering that, with reference to the environmental potential of the area, can be traced back to the evergreen Mediterranean forest dominated by Quercus ilex, presently only sporadically occurring in the area of the ruins, together with other species related to associations and upper syntaxa…
