Abstract Given the dioecious nature of date palms, selecting an effective pollinizer bearing a substantial quantity high-quality pollen is imperative. In this study, we investigated effects 11 male palm cultivars from Tunisia on production female trees, fruit sets, and characteristics 'Deglet Nour' cultivar dates. The comparison germination rates showed that ABD1 P169 pollens exhibited outstanding viability, with 98.7% 98.3%, respectively. On other hand, had highest rate, at 86.3%. most...
The work presented here aims to contribute with a sustainable alternative chemicals for avoiding deterioration of harvested date palm fruits by evaluating the single or combined use UV-C radiation and ozonated electrolyzed water (EW). In this way, effects light (0; 2.37; 6.22; 8.29 12.14 kJ m−2) alone, effect 6.22 m−2 neutral EW (NEW, pH 6.99, 870 mV ORP, 100 mg L−1 free chlorine), alkaline (AEW, 11.28, −880 1.83 chlorine) (O3, 0.55 mg/L ozone) on overall quality Deglet Nour dates stored 30...
The objective of this study was to assess the impact pulsed electric field (PEF) treatment on extraction polyphenolics and antioxidant activity from downgraded date palm fruits. PEF pretreatments (frequency: 30 Hz, time: 50 μs, pulse number: 240, strengths were found be 1, 2, 2.5 kV.cm−1, methanol (50%) temperatures (20, 40, °C)) optimized applied before produce an extract fruits with a high content bioactive compounds. extracts obtained immediately after analyzed for total polyphenolic...
This study assessed the total polyphenol, flavonoid, flavonols, and condensed tannins contents were also monitored their antioxidant properties in vitro investigated using 2,2-diphenyl-1-picrylhydrazyl radical cation, 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid), ferric reducing power, β-carotene-linoleic acid bleaching assay for second-grade dates (Phoenix dactylifera L.), from 10 Tunisian cultivars. The results prove that methanolic extracts of date fruits are a rich source...
This study addresses the development of unpollinated and pollinated flowers date palm (Phoenix dactylifera L.). cv. Deglet Noor in three successive seasons (2015–2017), focusing on physico-chemical characterization functional properties fruits at Kimri stage. Results showed for first time that dropped stage have a clear beneficial action human health compared even with Tamar stage, given its higher total polyphenols antioxidant activity, 3 34 times superior to respectively.
Biocontrol research has the potential for managing Fusarium root rot of olive.This latter is treated by use isolated bacteria from soil olive orchards Tunisia: Bacillus Licheniformis and Enterobacter Colcae.It was demonstrated that these two are effective against solani oxysporum.In an initial screening, efficacy were with a reduction disease incidence.In vitro, both biocontrol agents highly tolerant to carbendazime fungicide commonly used control diseases.It observed reduced symptoms at...
Three yeasts, Saccharomyces cerevisiae, Zygosaccharomyces rouxii and Candida pelliculosa, were tested for ethanol production on dates’syrup. In batch fermentation, the concentration depended initial sugar yeast strain. For an of 17.4°Brix, maximum was 63 g/L during S. cerevisiae growth, higher than amounts achieved Z. C. pelliculosa 33 41 respectively. On 35.8°Brix amount, only able to grow, resulting in 50 production, showing inhibitory effect S.cerevisae Pelliculosa due osmotic stress from...
Figs are an important constituent of the Mediterranean diet, widely consumed fresh. Due to their very short shelf life, postharvest techniques preserve quality and safety should be implemented. The current work aimed study combined effect a UV–C treatment (5 or 10 kJ m−2) followed by packaging under passive modified atmosphere (MAP) on physicochemical bioactive fresh figs (cv. 'Colar') stored up 12 d at 0 ºC (90–95% RH). As controls, untreated air-stored (AIR) samples were used. flesh...
O objetivo deste trabalho foi analisar as caracteristicas fisico-quimicas e sensoriais dos frutos de quatro variedades figueira (Colar, San Antonio, Cuello Dama Negro Tiberio) cultivadas no sudeste da Espanha. Para este estudo foram utilizados figos oriundos uma area experimental Escola Politecnica Superior Orihuela Universidade Miguel Hernandez Elche/Espanha. Os avaliados Laboratorio Pos-Colheita Cartagena/Espanha. Foram mensuradas como firmeza, pH, solidos soluveis, acucares, polifenois...
In the oasis of Tozeur (Tunisia) a peculiar date palm ploidy chimera was discovered, showing diploid (2n =2x) and tetraploid =4x) sector uniform offshoot.This allowed to describe effects chromosome doubling on some selected features.Because both ploidies occur within one plant, there no environmental bias.Tetraploid leaves are longer, bear larger leaflets spines have thicker rachis than normal leaves.During three seasons, inflorescences appeared ten days later their counterparts.The formed...
A stable tetraploid date palm mutant with the potential for increased fruit size was recovered from a sectorial di-tetraploid chimera via in vitro culture of flower explants. Callus induced using 2,4-D, followed by shoot regeneration on medium containing NAA and BAP rooting IBA. Regenerated plantlets, confirmed as flow cytometry, were acclimatized grown six years. The leaves tetraploids exhibited significantly wider petiole bases, thicker rachis spines, broader leaflets, more intense green...
