Grafting suitability of Sicilian eggplant ecotypes onto Solanum torvum: Fruit composition, production and phenology
2013
The eggplant (Solanum melongena L.) is one of the most widely cultivated crops in tropical and temperate regions around the world and is suitable for propagation through grafting. In many parts of the world, grafting is a routine technique used in continuous cropping systems, because in the horticulture field is a sustainable technique that allows cultivators to overcome abiotic or biotic stress. The objective of this research was to evaluate the suitability at the grafting of four Sicilian eggplant ecotypes grown in open field in Sicily, Italy. Vegetables in general are a great source of minerals in the human diet and the eggplant (Solanum melongena L.) provides significant quantities of v…
Molecular markers reflect differentiation of Fusarium oxysporum forma speciales on tomato and forma on eggplant
2013
Selective pressure induces pathogens to change their method of infection and, sometimes, causes species to become infectious. Pathogenic fungi must differentiate different morphological and physiological properties during the process of host specialization in their life cycle. In the present study, we conducted a genetic investigation and compared similarities within a generation of Fusarium oxysporum forma speciales (f. sp.) infecting tomato and forma (f.) infecting eggplants using selected ISSR and RAPD markers, two horticultural commodities belonging to the same taxon of the Solanaceae. Interestingly, genetic data showed that fungi belonging to F. oxysporum f. sp. infecting tomato have a…
Nursery and field evaluation of eggplant grafted onto unrooted cuttings of Solanum torvum Sw.
2014
Abstract Solanum torvum is the eggplant ( Solanum melongena ) relative most commonly used for grafting even if the nursery production of eggplants grafted onto this rootstock has some issues related to its long, irregular and erratic germination and slow growth and development of seedlings. Unrooted cuttings harvested from stock plants could be an alternative propagation material to obtain S. torvum rootstocks and might allow to overcome nursery production issues for eggplant. The aim of this work was to evaluate eggplant suitability to be propagated by unrooted grafted cuttings using S. torvum as rootstock and the influence of this propagation technique on plant yield and fruit quality. A …
Increase of trans-resveratrol in typical Sicilian wine using β-Glucosidase from various sources
2008
β-Glucosidase (EC 3.2.1.21) (β-G) from different sources were tested to increase the trans-resveratrol in some Sicilian wines by hydrolysing resveratrol glucoside. β-G from Aspergillus niger mould was tested as a crude and purified enzyme, and compared with the same enzyme from Saccharomyces cerevisiae yeast. Specific purification served to eliminate collateral enzyme activities so that β-G could be used simply and economically. Aspergillus niger β-G produced trans-resveratrol increases of up to 75%, with no change in physico-chemical properties and bouquet, and an increase in health and nutritional properties. S. cerevisiae β-G raised free-terpenol levels, but impaired wine colour due to a…
Effect of grafting on yield and quality of eggplant (Solanum melongena L.)
2013
Eggplants have fruits with different sizes, shapes and colours, according to the cultivar. Skin colour is due to anthocyanins, pigments located in the cell vacuole of fruit skin that belong to phenolic flavonoids, a powerful antioxidants group. Environmental conditions and growing techniques may influence fruits characteristics and their content of phenolic compounds. Grafting is a non chemical alternative for overcoming the effects of intensive and continuous cropping. The rootstocks preferred for eggplant are hybrids of tomato or tomato KVFN. Also species taxonomically close, as Solanum torvum, have been used and showed good vigour, compatibility and resistance to wilt disease. Informatio…
