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 …
EFFECT OF DIFFERENT ROOTSTOCKS ON VEGETATIVE GROWTH OF JAPANESE AND EUROPEAN PLUM CULTIVARS IN SOUTHERN ITALY: PRELIMINARY RESULTS
2007
The preliminary results of a new rootstock trial for Japanese and European plum cultivars are reported. Two clonal Prunus cerasifera ('Myrobalan 29C' and 'MrS 2/5'), two Prunus domestica ('Penta' and 'Tetra') and the peach × almond 'GF 677' were tested in a warm and dry climate of Southern Italy where the plum industry is recently increasing, particularly for the Japanese type. 'GF 677' showed the most vigorous habit together with a higher production at the first bearing year in comparison with 'Myrobalan 29C', while the two P. domestica types resulted in very low vigour. This result was more evident and statistically significant with the Japanese plum cultivar, whereas very low differences…
Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case …
2017
The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…
Effects of traditional and light pruning on viticultural and oenological performance of bobal and tempranillo vineyards
2015
<p style="text-align: justify;"><strong>Aim</strong>: Light pruning may improve vine yield and quality although vineyard responses are variable. We assessed the effects of traditional manual pruning and mechanical light pruning on the viticultural and oenological performance of <em>Vitis vinifera </em>cv. Bobal and cv. Tempranillo.</p><p style="text-align: justify;"><strong>Methods and results</strong>: During 2008-2011, Bobal and Tempranillo vineyards underwent traditional pruning or light pruning. The effects of both pruning techniques were determined in vine vigour and yield, and grape and wine characteristics. Both cultivars responde…
Host plant cultivar of the grapevine moth Lobesia botrana affects the life history traits of an egg parasitoid.
2009
6 pages; International audience; The quality and susceptibility of insect eggs for egg parasitoids may be affected by the diet experienced by the females that produce the host eggs. We tested the hypothesis that the host plant fed upon by an herbivore during the larval stages will determine the quality of the eggs laid by the adult for an egg parasitoid. We used the tritrophic system comprising five grape cultivars, the European grapevine moth, Lobesia botrana and the parasitoid Trichogramma evanescens. Parasitoid performance in host eggs of different sizes and originating from five grape cultivars was determined. Overall, egg parasitism was higher on cultivars on which L. botrana laid larg…
Research Regarding the Use of Wheat Biodiversity for Obtaining some Cereal-Based Fermented Mashes
2012
International audience; Cereal-based fermented beverages are an opportunity to include probiotics and fiber in human nutrition. Nowadays, increasing the interest for rediscovering the benefits, on scientific basis, of traditional fermented beverages based on cereals. Fermented mashes based on different cereal grist, namely Braga in Romanian, is a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. Physical-chemical and sensorial characteristics of these beverages depend on the ingredients and method of preparation. In this article was analyzed the influence of the five varieties of wheat on the main physical-chemical and sensorial c…

Hemp Flour Particle Size Affects the Quality and Nutritional Profile of the Enriched Functional Pasta
2023
The rheological and chemical quality of pasta samples, which were obtained using the durum wheat semolina fortified with the hemp seed solid residue, after oil extraction, sieved at 530 μm (Hemp 1) or 236 μm (Hemp 2) at different percentages of substitution (5%, 7.5%, and 10%, were evaluated. The total polyphenolic content in hemp flour was quantified in the range of 6.38–6.35 mg GAE/g, and free radical scavenging was included in the range from 3.94–3.75 mmol TEAC/100 g in Hemp 1 and Hemp 2, respectively. The phenolic profiles determined by UHPLC-ESI/QTOF-MS showed that cannabisin C, hydroxycinnamic and protocatechuic acids were the most abundant phenolic compounds in both…
Effect of different processing methods on the quality of obtained pomegranate juice
2019
Pomegranate juice has many health properties as the fruits contain anticarcinogenic, antimicrobial and antiviral compounds. Its consumption has greatly increased throughout the world in recent years due to the potential of its different components, polyphenols and anthocyanins mostly. Many studies have been performed on the pomegranate juice yield demonstrating its influence on the organoleptic and physicochemical properties of the juice. Commercial pomegranate juice production involves pressing the fruits. As a consequence, there is a need to investigate the pressing machine types and adjustment in order to maximize juice yield and enhance its health properties. The aim of this study was t…
Physicochemical, Nutraceutical and Sensory Traits of Six Papaya (Carica papaya L.) Cultivars Grown in Greenhouse Conditions in the Mediterranean Clim…
2020
Six papaya (Carica papaya L.) cultivars, grown in a Mediterranean climate under greenhouse conditions, were screened for physicochemical properties, antioxidant capacity, nutritional and sensory characteristics. The fruits, harvested with more than 50% of yellow surface (between 60% and 77%) were tested for carotenoids content, phenolic content, reducing activity (ABTS) and cellular antioxidant activity (CAA50). The physicochemical traits were measured in terms of the titratable acidity and soluble content whereas proximal composition along with moisture, fats, total sugar, ash, vitamin A, C and E content. Moreover, the sensory profile was analyzed by a semi-trained panel. Although the six …
