    β-Cyclodextrin-Based Nitrosoglutathione Improves the Storage Quality of Peach by Regulating the Metabolism of Endogenous Nitric Oxide, Hydrogen Sulfide, and Phenylpropane

    Chen Chen, Shuhua Zhu*

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1091-1107, 2023, DOI:10.32604/phyton.2023.026331

    Abstract Nitrosoglutathione (GSNO) and β-cyclodextrin (β-CD) exhibit positive roles in regulating fruit quality. However, there are few reports about the effects of GSNO and β-CD on enhancing storability and boosting nitric oxide (NO), hydrogen sulfide (H2S), and phenylpropane metabolism in fruits during storage. “Xintaihong” peach were treated with 0.5, 1.0, 1.5 mmol L−1 GSNO in 0.5% (w/v) β-CD solution (GSNO/β-CD). The effects of GSNO/β-CD on endogenous NO, H2S, and phenylpropane metabolism were investigated. Treatment with GSNO/β-CD increased the color difference of peach and inhibited the increase of respiratory intensity, weight loss, and relative conductivity. Treatment with 1.0 mmol… More >

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

    Tahsin Shoala1, Basma H. Amin2, Ismail A. S. Rashid3, Fayz A. Abdel-Rahman3, Mohamed E. Khalil3, Khamis Youssef3,*

    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 >

    EfficientNet-Based Robust Recognition of Peach Plant Diseases in Field Images

    Haleem Farman1, Jamil Ahmad1,*, Bilal Jan2, Yasir Shahzad3, Muhammad Abdullah1, Atta Ullah4

    CMC-Computers, Materials & Continua, Vol.71, No.1, pp. 2073-2089, 2022, DOI:10.32604/cmc.2022.018961

    Abstract Plant diseases are a major cause of degraded fruit quality and yield losses. These losses can be significantly reduced with early detection of diseases to ensure their timely treatment, particularly in developing countries. In this regard, an expert system based on deep learning model where the expert knowledge, particularly the one acquired by plant pathologist, is recursively learned by the system and is applied using a smart phone application for use in the target field environment, is being proposed. In this paper, a robust disease detection method is developed based on convolutional neural network (CNN),… More >

    Nitric Oxide Regulates Mitochondrial Fatty Acids and Promotes CBF Expression of Peach Fruit during Cold Storage

    Xiaoshan Guo1,2, Dandan Huang2, Siyu Wen2, Yang Bai2, Shuhua Zhu2,*, Jianrong Feng1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.2, pp. 409-427, 2022, DOI:10.32604/phyton.2022.018022

    Abstract Low-temperature storage is convenient for postharvest preservation of peach fruit, but peach fruit is sensitive to cold damage, which lowers its quality. Nitric oxide (NO) has the potential to improve the bitter resistance of peach fruit. In this work, peach fruit was treated with 15 μmol L−1 NO and 5 μmol L−1 c-PTIO [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxo-3-oxide], to study changes in mitochondrial fatty acids and expression of the C-repeat binding factor (CBF). The results showed that 15 μmol L−1 exogenous NO significantly maintained fruit quality, reduced peroxidation of mitochondrial fatty acids, increased the activities of the antioxidants superoxide dismutase (SOD),… More >

    PeachNet: Peach Diseases Detection for Automatic Harvesting

    Wael Alosaimi1,*, Hashem Alyami2, M. Irfan Uddin3

    CMC-Computers, Materials & Continua, Vol.67, No.2, pp. 1665-1677, 2021, DOI:10.32604/cmc.2021.014950

    Abstract To meet the food requirements of the seven billion people on Earth, multiple advancements in agriculture and industry have been made. The main threat to food items is from diseases and pests which affect the quality and quantity of food. Different scientific mechanisms have been developed to protect plants and fruits from pests and diseases and to increase the quantity and quality of food. Still these mechanisms require manual efforts and human expertise to diagnose diseases. In the current decade Artificial Intelligence is used to automate different processes, including agricultural processes, such as automatic harvesting.… More >

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

    Meiling Tang1,2,#, Yuhe Li1,3,#, Yahui Chen1,4, Lei Han1,3, Hongxia Zhang1,3, Zhizhong Song1,3,4,*

    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 >
