In questa tesi di dottorato sono stati indagati i punti critici legati ai fattori biotici e abiotici che possono influenzare la crescita del fungo Fusarium verticillioides, produttore di fumonisine in mais. le fumonisine sono metaboliti secondari prodotte da funghi appartenenti al genere Fusarium e sono state classificate come possibili cancerogene per l’uomo e per gli animali. Gli argomenti trattati nei vari capitoli sono stati: parametri ecologici che condizionano la crescita e l’accumulo di fumonisine nelle prime fasi post raccolta e durante lo stoccaggio; relazione che intercorre tra aw, umidita’ relativa e tipo di ibrido; controllo con mezzi chimici e biologici in campo e in vitro su F. verticillioides e A. flavus.

Abstract
The aim of this work was to collect missing information about critical point related to abiotic and biotic factors that can influence the growth of Fusarium verticillioides in maize and the consequent production of fumonisins in kernels. Fumonisins are secondary metabolites reported as toxigenic in humans and animals. Issues treated are: variables influencing growth and toxin accumulation during post-harvest and storage; the relationship between aw, relative humidity and type of hybrids; chemical and biological control of F. verticillioides e A. flavus in field and in vitro.File | Dimensione | Formato | |
