Oxylipin mediated stress response of a miraculin-like protease inhibitor in Hexanoic acid primed eggplant plants infested by Colorado potato beetle
2017
Insect-plant interactions are governed by a complex equilibrium between the mechanisms through which plant recognize insect attack and orchestrate downstream signaling events that trigger plant defense responses, and the mechanisms by which insects overcome plant defenses. Due to this tight and dynamic interplay, insight into the nature of the plant defense response can be gained by analyzing changes in the insect herbivores digestive system upon plant feeding. In this work we have identified a Solanum melongena miraculin-like protease inhibitor in the midgut juice of Colorado potato larvae feeding on eggplant plants treated with the natural inducer of plant defenses hexanoic acid. We analy…

Grafting affects yield and phenolic profile of Solanum melongena L. landraces
2016
Abstract The influence of grafting on agronomical and qualitative characteristics of four Sicilian eggplant landraces was investigated. Grafted and ungrafted plants were compared in the open field in the northern coast of Sicily. Solanum torvum seedlings were used as rootstock. Regardless of genotypes tested, grafting significantly increased total fruit production, marketable production, and number of marketable fruits, but did not affect weight of marketable fruits and waste production. Landrace 2 (Sciacca), with black epidermal tissue and pyriform fruit shape, when grafted onto S. torvum not only gave a higher yield performance than ungrafted plants, but also showed a higher phenolic anti…
Solanum aethiopicum gr. gilo and Its Interspecific Hybrid with S. melongena as Alternative Rootstocks for Eggplant: Effects on Vigor, Yield, and Frui…
2019
Grafting is generally considered effective in ameliorating vegetable crop tolerance to biotic and abiotic stresses. The use of interspecific hybrid as rootstock for eggplant may represent a valid alternative approach to enhance eggplant performance. However, studies on the effects of different rootstocks on eggplant plant vigor, yield, and fruit quality traits often show conflicting results. Thus, an experiment was performed in two spring&ndash
Hybrids and allied species as potential rootstocks for eggplant: Effect of grafting on vigour, yield and overall fruit quality traits
2018
Abstract Grafting of fruiting vegetables is an effective technique to overcome pests and diseases in modern cropping systems and it is often used to improve yield and fruit quality. Eggplant is an important vegetable crop that benefits significantly from grafting. In this regards, the exploitation, valorization and breeding of new rootstock genotypes as possible substitute to those commonly used (Solanum torvum and tomato hybrids) would permit an intensive eggplant crop system in those situations where a rootstock rotation is required. In the present article, we study the effects of several potential rootstocks including both wild/allied species of eggplant [S. torvum (STO), S. macrocarpon …
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…
Recovery of anthocyanins from eggplant peel
2009
Abstract Tartaric and malic acid solutions were tested to extract anthocyanins from eggplant peel by a discontinuous process to obtain a natural red colorant. Extraction optimization was carried out, using different solvents, acid concentration, temperature, time of extraction and solvent-to-solid ratio as independent variables. Tartaric acid was more efficient than malic acid in both extraction yield and rate. Comparative tests were carried out using acidified ethanol as solvent. Delphinidin-3-rutinoside was extracted and identified as the major anthocyanin in eggplant peel. Concentration of different extracts from eggplant peel was carried out using EXA-31, a methacrylic food grade resin,…
PLANTING DENSITY AND PRUNING METHOD AFFECT EGGPLANT SOILLESS CULTURE
2007
The aim of this research was to evaluate the effects of two planting densities (1.6 plants-m-2 or 2.5 plants-m-2) and two pruning methods (two or four stemmed plants) on eggplant cultivars Black Bell and Longo in soilless culture. The research was carried out in 2003-2004 in the Northern coast Sicily. Eggplant plug plants were transplanted in a heated glasshouse in polystyrene containers (80 cm in length, 25 cm in width, 20 cm in height) filled with coconut coir dust. The experimental design was a split-split plot. Fruit production from January to April increased significantly as planting density increased. Irrespectively of the cultivars, four stemmed plants gave higher yields than two ste…
Agronomic performance and fruit quality in greenhouse grown eggplant are interactively modulated by iodine dosage and grafting
2022
Iodine (I) is considered an indispensable trace element for humans due to its capacity to promise a normal functions of thyroid hormones, preventing cretinism, goiter, reproductive failure, and diverse types of brain injury. Vegetable grafting is a technique for securing yield constancy and/or improving fruit quality. The study evaluated the combined effect of I-dosages and grafting onto Solanum torvum rootstock on 'Birgah' eggplant. Iodine at 100 or 300 mg L-1 enhanced marketable yield by 28.8% and 8.5%, respectively, compared with the control. Plants grafted onto S. torvum and self-grafted plants increased marketable yield by 53.0% and 45.8%, respectively compared with the ungrafted plant…
Solid-state 1H-NMR relaxation properties of the fruit of a wild relative of eggplant at different proton Larmor frequencies
2009
1H longitudinal relaxation time profiles (T1) at different proton Larmor frequencies were registered for a solid state plant tissue by using fast field cycling (FFC) nuclear magnetic resonance (NMR) spectroscopy. T1 distributions were obtained and the curves deconvoluted in order to differentiate among the different T1 components. Among the components, two were assigned to hydrophobic (e.g. fatty acids) and hydrophilic (e.g. saccharides) molecular systems, whereas the remaining others were attributed to bulk and bound water. This paper showed for the first time solid state FFC-NMR spectroscopy applied to plant tissue, and revealed that relaxometry is a very promising technique for studying …
