The study aims to explore the effects of different grafting combinations on the growth of eggplants under diverse greenhouse conditions. Eggplant cultivar Black bell (Bb) was employed as scion, while the hybrid F1 Beaufort (Be) and Solanum torvum (To) were utilized as rootstock. The hypothesis behind this study pertains to grafting incompatibility with Beaufort F1. It postulates that this incompatibility can be mitigated by manipulating soil and greenhouse temperatures. The experimental factors encompassed plant combinations (Bb, Be/Bb and To/Bb), as well greenhouse and substrate temperature (both cold or heated). The Be/Bb combination showed higher values of plant vegetative traits, but it exhibited low grafting compatibility. Additionally, physiological analysis confirmed the presence of excessive growth and vegetative disorder within the Be/Bb combination. Examination of the xylem vessels rev...

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 hemp flours. Among the amino acids, isoleucine, glutamine, tyrosine, proline, and lysine were the most abundant in raw materials and pasta samples. Although the hemp seeds were previously subjected to oil extraction, hemp flours retain about 8% of oil, and the fatty acids present in the largest amount were linolei...

Among the cultivated species of Brassica, many traditional European crops belonging to several cultigroups of Brassica oleracea, in the recent decades became very popular in Asia, whereas their presence in Europe has been quite stable. Recently, several Authors showed molecular DNA evidences supported by literature on the wide diversity of Mediterranean Brassica wild species in comparison to the B. olearacea wild type populations of north European Atlantic coasts, thus indicating that domestication of B. olearacea cultigroups occurred in the Greek-speaking area of the north-central and northeast areas of the Mediterranean basin (Mitchell, 1976; Song et al., 1980; Allender et al., 2007; Maggioni et al., 2010). These Brassica wild relatives are perennial, diploid (2n=18), cross-pollinated, often se...

The oil fatty acid profile is similar to sunflower one, making this crop usable for human consumption. The oil contains also high levels of α-tocopherol, which offers stability against oxidation. Moreover, genotypes characterized by high acid oleic content, useful for biodiesel production, are in selection. In the last years the interest in antioxidant biocompounds source from agricultural wastes or from grains after extraction of oil is growing. In this work data concerning chemical characterization for antioxidant compounds of the whole seed and its partitioning is explored using achenes of Cynara cardunculus var. altilis Line 01-2011. Heads were threshed with a specific mini thresher to separate grains (achenes), which were then weighed to determine 1000 seed weight. Some seeds were utilized to obtain hull (H) and kernel (K), some others were analysed in whole (W). The incidence of hull on the whole seed was determined. On each part of the achenes the moisture content was measured. Grain lipid substances were extracted and quantified by the Soxhlet method. After oil extraction, the phenolic acids characterization (chlorogenic acid, caffeic acid, catechin), was performed by uHPLC-Dionex in H, K and W, separately. Results showed that about 45% of whole seed was hull. Differences in oil amount between kernel and whole seed were recorded, resulting more concentrated in K (398 g kg-1 DM) than W (226 g kg-1 DM). The hull resulted rich in phenolics (as sum of chlorogenic acid, caffeic acid, catechin), which can be recovered after oil extraction with a content higher than 5,000 mg kg-1 DM.

In fact, in the Mediterranean countries a wide biodiversity of Brassica genus of both wild and cultivated species is present; moreover, among the mentioned countries, Sicily is supposed to be the centre of origin and diversification of broccoli and cauliflower. In this regard, the first step of the work carried out by DOFATA was the identification of the population sites of Brassica wild species growing in Sicily, with the aim to monitor the population size and to characterize and evaluate the different genotypes for a possible use in plant breeding. Thereafter, the working plan aimed at defining strategies to prevent germplasm erosion in these species by establishing genetic reserves. The present work is within the frame of EU AEGRO proj...

In the present work, we show a survey on five kohlrabi genotypes (CR13, CR17, CR22, CR25 and CR29) cultivated in Southern Italy. We measured the content of glucosinolates (GLS), total phenols (PC), ascorbic acid (AsA), total anthocyanins (ATH), total carotenoids (CAR) and the antiradical activity on different parts of the plant (skins, stems and leaves). Four GLS were identified in the leaves, i.e., glucoraphanin, glucobrassicin, gluconasturtiin and neo-glucobrassicin. The GLS profile of the stems and leaves were similar. However, stems showed a lower GLS amount and the presence of glucoerucin. The total polyphenols and AsA content was slightly higher in the leaves than in the stems. With regards to ATH, higher values were found in the leaves with respect to the skins, with the exception of CR17. The values of antiradical activity differed depending on the method of measurement. The leaves genera...

Among the main objectives pursued by the research institutions involved should be highlighted: the creation of a world germplasm bank located in Cuenca (Spain) where they were stored and propagated accessions of Crocus sativus L. crops in major growing areas of the world and those attributable to Crocus spp. naturally occurring in the countries participating in the project; the development of descriptors for morphological, agronomic and chemical genetic materials; the assessment to the abiotic and biotic stress, etc. Were collected in total 443 accessions, including 197 ones of C. sativus L., from 15 countries, and 246 accessions of Crocus spp. collected in 12 cou...

This study aimed to analyze the enzyme systems involved in inulin metabolism in the roots of one Sicilian wild cardoon population in relation to the plant’s growth and development stages. During the winter season, the plant showed slow growth; its biomass was represented mainly by leaves and saccharides were mobilized into its roots. During the spring season, the plant doubled its growth rate and differentiated its reproduction organs as a consequence of the cold conditions. The maximum activities of the 1-SST were recorded in line with the high sucrose and inulin levels in roots, which increased quickly. The increase in the 1-FEH activity suggests that fructan-hydrolyzing activity is associated with the sprouting and elongation of plant stalks. The peak of the invertase activity occurred before the 1-FEH peak. The inulin accumulation in the wild cardoon roots was associate...

Agroecological soil management based on biocontrol agents and natural compounds has had increased grower interest in order to reduce chemical residues in the produce and to adopt environmentally friendly farming methods. In this frame, we evaluate and validate soil biofumigation by the use of glucosinolate (GLS) compounds. Among them, sinigrin showed biocontrol activities against several pests and diseases via nematotoxic action. Among the Brassicaceae species rich in sinigrin, we chose Brassica macrocarpa Guss. (BM) because its leaves show 90% of all GLSs, and we could better estimate the action of this single GLS. Different dosages of BM leaf flour, containing 200 to 300, 350, 400, 450, and 650 μmol m−2 of sinigrin, were inserted into soil already infected by Meloidogyne spp....
