Cooking influence on physico-chemical fruit characteristics of eggplant (Solanum melongena L.)
2016
Physico-chemical traits of three eggplant genotypes ("Tunisina", "Buia" and "L 305") were evaluated before and after two cooking treatments (grilling and boiling). Different genotypes revealed different changes after cooking, with "Tunisina" showing a better retention of phytochemicals with respect to other two genotypes. The main physical phenomena were water loss during grilling, and dry matter loss after boiling. Chlorogenic acid, the main phenolic in eggplant, resulted higher in grilled samples, while delphinidin glycosides resulted more retained in boiled samples. Glycoalkaloids, thiols and biogenic amines were generally stable, while 5-hydroxy-methyl-furfural was found only in grilled…
Un-rooted grafted cuttings for eggplant plug-transplant production and shipping: simulated transportation and healing requirements
2019
Vegetable grafting is one of the most effective eco-friendly techniques to overcome pests and soilborne diseases in modern cropping systems of fruiting vegetables. Due to the increased farmers’ preference for grafted seedlings of high quality and better performance, the use of vegetable grafted plants is rapidly spreading and expanding over the world and intensive researches on new commercial production systems are under way. However, in many areas of the world, due to the high cost of skilled manpower, the use of grafted plug plants is still limited causing a relatively slow development of the grafting nursery industry. The aim of this work was to evaluate a possible use of un-rooted graft…
Morphological and agronomical characterization of eggplant genetic resources from the Sicily area
2013
The eggplant is a vegetable crop widely grown throughout Sicily both in greenhouse and open field. This study was carried out by the Department of Agri-Environmental Systems at the University of Palermo in the Spring/Summer of 2011 in open fields. The aim of the study was to characterize 6 eggplant ecotypes (G1-G6) and three eggplant varieties (Birgah, Black bell and Viola di Firenze) from a morphological, phenological and production point of view, gathered from Sicily and the smaller islands. The genotypes G1 and G3 were found to be more productive than the varieties used in the test field. Ecotype G1 produced fruits which were dark violet and highly glossy, and produced the lowest percent…
NECREMNUS ARTYNES (WALKER) PARASSITOIDE DI TUTA ABSOLUTA (MEYRICK) SU POMODORO, MELANZANA E SOLANUM NIGRUM L. IN SERRA A CONDUZIONE BIOLOGICA
2011
Nel 2010, in serre del palermitano gestite secondo i canoni dell'agricoltura biologica, è stato condotto uno studio volto all'individuazione degli antagonisti naturali indigeni del lepidottero gelechide Tuta absoluta, fitofago esotico dannoso alle solanacee recentemente introdotto in Italia. Le piante campionate sono state il pomodoro, da gennaio a giugno, la melanzana, da fine marzo a giugno, e Solanum nigrum che cresceva spontaneamente all'interno delle serre in piccoli spazi liberi dalle solanacee coltivate. Per tenere sotto controllo il gelechide, il serricoltore ha effettuato tre trattamenti con Bacillus thuringiensis da metà marzo a fine aprile. Oltre al predatore Nesidiocoris tenuis,…
