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…

Might exogenous circular RNAs act as protein-coding transcripts in plants?

2021

Circular RNAs (circRNAs) are regulatory molecules involved in the modulation of gene expression. Although originally assumed as non-coding RNAs, recent studies have evidenced that animal circRNAs can act as translatable transcripts. The study of plant-circRNAs is incipient, and no autonomous coding plant-circRNA has been described yet. Viroids are the smallest plant-pathogenic circRNAs known to date. Since their discovery 50 years ago, viroids have been considered valuable systems for the study of the structure-function relationships in RNA, essentially because they have not been shown to have coding capacity. We used two pathogenic circRNAs (Hop stunt viroid and Eggplant latent viroid) as …

Grafting Eggplant Onto Underutilized Solanum Species and Biostimulatory Action of Azospirillum brasilense Modulate Growth, Yield, NUE and Nutritional…

2022

The grafting of vegetable crops is considered a valuable mean for ensuring the yield and quality under different cultivation conditions. Simultaneously, there are increasing research efforts in exploiting underutilised plants as potential rootstocks for vegetables to increase the sustainability of horticultural systems. In accordance with the European Green Deal, the application of biostimulants is a fashionable and ecological agronomic practice to enhance the production and quality of vegetables. Thus, the current research appraised the synergistic effect of grafting eggplant onto various allied potential rootstocks (Solanum torvum, S. aethiopicum and S. macrocarpon) and of applying a plan…

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,…

Effect of grafting, cultivar and cold storage on eggplant fruits

2011

Eggplant is a perishable fruit that, once harvested, can be stored at 10 °C for several days. If long stored, fruits reduce their texture, skin brightness and become rubbery. Recently, grafting onto Solanum torvum has become more and more used to give resistance to biotic and abiotic stresses. The aim of this work was to study the effect of grafting, cultivar and cold storage on post-harvest changes of eggplant fruits. Grafted or ungrafted plants of four cultivars were grown in an unheated greenhouse during autumn-spring period. Three cultivars had skin with very dark purple colour (Black Bell, Black Moon and Longo) and one had skin with unhomogeneous light purple colour (Birgah). After har…

Effects of polyethylene and biodegradable starch-based mulching films on eggplant production in a Mediterranean area

2018

Traditional plastic films are used for eggplant cultivation in open field in Mediterranean environments. However, disposal and/or recycle of mulches contaminated with soil and/or vegetation represent an environmental concern. We compared two traditional plastic mulches (transparent and black polyethylene films) with five black biodegradable mulching films (Mater-Bi T12A, Mater-Bi T12B, Mater-Bi T15A, Mater-Bi T15B and Mater-Bi T15C) having different thickness and synthetic composition. 'Birgah' eggplant F1 hybrid plug-plants were transplanted on 2nd May, 2016 in the north-western coast of Sicily. Air temperature in the soil-mulch film gap in the plots with transparent PE was higher than in …

Stand-Alone or Combinatorial Effects of Grafting and Microbial and Non-Microbial Derived Compounds on Vigour, Yield and Nutritive and Functional Qual…

2022

The current research investigated the effects of endophytic fungi such as Trichoderma atroviride (Ta) or Ascophyllum nodosum seaweed extract (An) and their combination on growth, yield, nutritive and functional features, and mineral profile of ‘Birgah’ F1 eggplant either ungrafted, self-grafted or grafted onto the Solanum torvum rootstock. Eggplant exposed to An or An+Ta had a significant increase in root collar diameter 50 days after transplanting (RCD50), total yield (TY), marketable yield (MY), ascorbic acid (AA) content, Mg, Cu, and Zn concentration, and a reduction in glycoalkaloids (GLY) compared with the control. Furthermore, grafted plants had a higher TY, MY, number of marketable f…

Interference of tributyltin(IV)chloride on the vascular plant cells

2007

In the recent past years, interest in the environmental impact of organotin(IV) compounds has risen markedly. Considering that most data in the scientific literature refers to the animal kingdom and not to higher plants cells, we tested the effects of organotin compounds on vascular plant cells, by studying the interaction of tributyltin chloride (TBTCl) with Allium cepa, Solanun tuberosum and Solanum melongena, vascular plants that are directly involved in the human food chain. The TBTCl effects on mitotic metaphase plates, on pollen grains and on both microtubers and adult tuber parenchymatic cells were investigated and the concentrations of TBTCl inside the treated parenchymatic cells we…

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 …
