Selenium biofortification and grafting modulate plant performance and functional features of cherry tomato grown in a soilless system
2021
Abstract Selenium (Se) is an essential trace element for humans due to its importance in a number of enzymes. Vegetable grafting is a valuable tool to overcome biotic and/or abiotic issues and to increase vigour, yield traits and fruit quality. The present work aimed at testing both different Se concentrations (0.0, 1.0, 2.0 and 4.0 μmol Se L−1) supplied via fertigation and grafting on cherry tomato in soilless culture. Se at 2.0 μmol L−1 improved total fruit yield by 60.0 % and 31.4 % in ungrafted and grafted plants, respectively as compared to the control. Marketable yield was positively affected by Se-biofortification and grafting. Se at 2.0 μmol L−1 improved N use efficiency by 60.3 % a…
Protein hydrolysates and mo-biofortification interactively modulate plant performance and quality of ‘canasta’ lettuce grown in a protected environme…
2021
Since the use of protein hydrolysates (PHs) enhances overall plant performance and quality of vegetables, they might be considered as a toll to face a number of concerns essentially associated to the growing request of premium quality foodstuff realized in agreement with eco-friendly agriculture practices. Molybdenum (Mo) is considered a fundamental trace element for human body. Thus, its shortage determines several disorders mainly related to neurological lesion and esophageal cancer. Biofortification of fruiting and leafy vegetables is a promising tool to prevent Mo deficiency in the human diet. The current study was carried out to assess the interactive effect of plant-derived PHs and Mo…
Iodine Biofortification Counters Micronutrient Deficiency and Improve Functional Quality of Open Field Grown Curly Endive
2021
Human iodine (I) shortage disorders are documented as an imperative world-wide health issue for a great number of people. The World Health Organization (WHO) recommends I consumption through ingestion of seafood and biofortified food such as vegetables. The current work was carried out to appraise the effects of different I concentrations (0, 50, 250, and 500 mg L−1), supplied via foliar spray on curly endive grown in the fall or spring–summer season. Head fresh weight, stem diameter, head height, and soluble solid content (SSC) were negatively correlated to I dosage. The highest head dry matter content was recorded in plants supplied with 250 mg I L−1, both in the fall and spring–summer se…

Impact of Ecklonia maxima Seaweed Extract and Mo Foliar Treatments on Biofortification, Spinach Yield, Quality and NUE
2021
Seaweed extract (SE) application is a contemporary and sustainable agricultural practice used to improve yield and quality of vegetable crops. Plant biofortification with trace element is recognized as a major tool to prevent mineral malnourishment in humans. Mo deficiency causes numerous dysfunctions, mostly connected to central nervous system and esophageal cancer. The current research was accomplished to appraise the combined effect of Ecklonia maxima brown seaweed extract (SE) and Mo dose (0, 0.5, 2, 4 or 8 µmol L−1) on yield, biometric traits, minerals, nutritional and functional parameters, as well as nitrogen indices of spinach plants grown in a protected environment (tunnel).

In vitro bioavailability of iron and calcium in cereals and derivatives: A review
2016
Cereals are a staple food in both developed and developing countries, and are considered to be the best vehicle for iron and calcium fortification, as an important strategy for combating dietary deficits. Inadequate dietary intake of iron and calcium is related to a number of disease conditions such as anemia, osteoporosis, hypertension, and different cancers. From a nutritional point of view, it is interesting to know not only the amount of minerals consumed, but also their bioavailability. The present study reviews the current knowledge on the in vitro bioavailability of iron and calcium in cereals, placing emphasis on the methodologies used and on the influence of dietary factors and foo…
Effect of iron chelates on oil–water interface, stabilized by milk proteins: The role of phosphate groups and pH. Prediction of iron transfer from aq…
2010
International audience; Iron incorporated into food systems induces oxidation and precipitation. The consequences are reduced bioavailability and a functional modification of other food components such as proteins. The iron-chelates such as ferrous bisglycinate represent a possibility to avoid side effects, since the iron is protected. The aim of this study is to investigate the effects of iron-chelates compounds on the properties of an oil/water interface stabilized by caseinate or β-lacotoglobulin, under environmental conditions at 20 °C. Analyses were performed using dynamic drop tensiometry during 5000 s. The aqueous bulk phase is an imidazole/acetate buffer (0.1 M), containing 0.4 × 10…
La fortificación del Reino de Valencia en la década de1640 a la luz de la revolución militar
2019
This article proposes a study of the traditions in defensive architecture that concurred in the projects designed by Spanish military engineers for the fortification of the Valencian frontier in 1648 and 1649, in the context of the War of Catalonia (1640-1652). For this it is essential to follow the route of the Valencian adaptations to the military revolution in the matter of fortifications throughout the sixteenth century and compare them with those brought to Valencia in 1641 by the Marquis of Leganes and his engineers from the school of Milan.
Le site de Gaillardon à Ménétru-le-Vignoble (Jura) : un établissement de hauteur de l'Antiquité tardive et du haut Moyen Âge
2011
L'étude de l'établissement de Gaillardon à Ménétru-le-Vignoble s'inscrit dans le cadre d'un programme de recherche pluridisciplinaire engagé sur les sites de hauteur de l'Antiquité tardive et du haut Moyen Âge dans le département du Jura. Créé ex nihilo vers le début du ve siècle, ce lieu semble avoir été occupé de manière permanente jusqu'au vie siècle. Les aménagements identifiés à l'intérieur de l'enceinte maçonnée, qui enserre une superficie de 1,5 ha, suggèrent une concentration d'activités artisanales diversifiées. Certaines catégories de mobilier reflètent un niveau de vie aisé d'une partie des occupants ainsi que la présence d'une garnison ou d'une milice armée. Cet établissement pa…
Diagnostics for the knowledge: the case of the tower of Palazzo Termine Pietragliata in Palermo (Italy)
2015
[EN] Developing a methodological approach is crucial to assess the state of conservation of a monument, starting from the overall analysis, progressively moving from small to medium scale and reaching the grand scale at the end. Considering the territory, causes are investigated in order to understand the propensities, as well as considering a single monument, evidences are carefully read to assess the overall conditions, that will be lately detailed by the analysis on materials and their degradation. The object of this study is the tower of the Palazzo Pietragliata in Palermo, one of the most important examples of the late Gothic civil architecture in Sicily. The Palace, built in 1473 by P…
