    The Potential Efficacy of Glycyrrhizic Acid and Its Nanostructure Against Brown Rot of Peach fruits

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1139-1152, 2023, DOI:10.32604/phyton.2023.026515

    Abstract Production of peaches (Prunus persica (L.) Batsch) for both local market and export is increasing each year in Egypt. Brown rot disease, caused by Monilinia laxa and Monilinia fructigena, is considered one of the most important postharvest rots affecting peaches in Egypt and economic losses are increasing. Antifungal activity of glycyrrhizic acid nanoparticles (GA-NPs) and glycyrrhizic acid (GA) at 0.2 and 0.4 mmol/L was investigated as a control for both these brown rot pathogens on peach fruits in both in vitro and in vivo studies. In the in vitro studies, GA-NPs were the most effective as shown by the ability to… More >

    Characterization and Expression of Ammonium Transporter in Peach (Prunus persica) and Regulation Analysis in Response to External Ammonium Supply

    Phyton-International Journal of Experimental Botany, Vol.89, No.4, pp. 925-941, 2020, DOI:10.32604/phyton.2020.011184

    Abstract As the preferred nitrogen (N) source, ammonium (NH4+ ) contributes to plant growth and development and fruit quality. In plants, NH4+ uptake is facilitated by a family of NH4+ transporters (AMT). However, the molecular mechanisms and functional characteristics of the AMT genes in peach have not been mentioned yet. In this present study, excess NH4+ stress severely hindered shoot growth and root elongation, accompanied with reduced mineral accumulation, decreased leaf chlorophyll concentration, and stunned photosynthetic performance. In addition, we identified 14 putative AMT genes in peach (PpeAMT). Expression analysis showed that PpeAMT genes were differently expressed in peach… More >

    Physiological traits during ripening showing the appropriate timing for harvest to improve the organoleptic quality of “Flavorcrest” peach (Prunus persica L. Batsch)

    Altube HA, MG Ontivero Urquiza, RS Rivata, L Baghin, RJ Taborda, MP Blanco

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 79-83, 2017, DOI:10.32604/phyton.2017.86.079

    Abstract Determining the harvest time is a difficult decision for the fruit grower. The objective of this paper was to study the changes of some variables involved in the ripening of the fruit to determine the adequate harvest time. This would help to guarantee high-quality fruits in “Flavorcrest/Nemared” peach trees. Plants were set to the free palmette system at 4.5 x 3 m with a drip irrigation system. Harvesting was complete in three trees at three dates. Fruit weight, height and diameter, flesh firmness, total soluble solids and acidity were evaluated at harvesting and after three… More >
