    Photosynthetic Gas Exchange and Nitrogen Assimilation in Green Bean Plants Supplied with Two Sources of Silicon

    Julio C. Anchondo-Páez, Esteban Sánchez*, Carlos A. Ramírez-Estrada, Alondra Salcido-Martínez, Erick H. Ochoa-Chaparro

    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 963-980, 2024, DOI:10.32604/phyton.2024.048742

    Abstract Beans contain a wide range of vitamins, proteins, calcium, and zinc which make them an important food source for many countries. To meet the demand for bean production worldwide, large amounts of fertilizers and pesticides are used. However, the cost of production and environmental impact increases. To produce food sustainably, the use of beneficial nutrients such as silicon as a biostimulant has been proposed. However, information about the effect of different sources of silicon on the metabolism of bean plants is scarce. Bean plants cv. Strike were grown in pots for 60 days and the… More >

    Physiological and Biochemical Mechanisms of Salinity Tolerance in Carex morrowii Boott

    Aysegul Akpinar*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2197-2210, 2023, DOI:10.32604/phyton.2023.029006

    Abstract Carex species are widely used in many parts of the world and contain a large number of ecologically diverse species. Among the Carex species, some of them are known to be glycophytes, while others are halophytes. Carex morrowii Boott (Cyperaceae) is resistant to trample through their root structure and has an essential ornamental value in the landscape with their leaves. However, no information was found about the level of salinity tolerance/ sensitivity of the Carex morrowii among these species. In the present study, changes in trace element contents (Na, K, Ca, Cu, Mn, Mg, Ni, Fe, P,… More >

    Effects of Different Nitrogen and Phosphorus Synergistic Fertilizer on Enzymes and Genes Related to Nitrogen Metabolism in Wheat

    Yajun Li, Yihui Wang, Shuang Chen, Yu Gao, Yan Shi*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2151-2164, 2023, DOI:10.32604/phyton.2023.027930


    In recent years, in order to improve nutrient use efficiency, especially nitrogen use efficiency, fertilizer value-added technology has been developed rapidly. However, the mechanism of the effect of synergistic fertilizer on plant nitrogen utilization is not clear. A study was, therefore, conducted to explore the activities and gene expression of key enzymes for nitrogen assimilation and the gene expression of nitrogen transporters in wheat after the application of synergistic fertilizer. Soil column experiment was set up in Qingdao Agricultural University experimental base from October 2018 to June 2019. Maleic acid and itaconic acid were copolymerized with

    Nitrate reductase activity, biomass, yield, and quality in cotton in response to nitrogen fertilization

    Hernández-Cruz AE1, E Sánchez2*, P Preciado-Rangel1, M L García-Bañuelos2, A Palomo-Gil1, A Espinoza-Banda1

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 454-460, 2015, DOI:10.32604/phyton.2015.84.454

    Abstract In the production of cotton (Gossypium hirsutum L.), nitrogen fertilization is one of the most costly crop practices, but important to reach high yields. However, high nitrogen (N) content in plants does not always translate into a high fibre production. One way of assessing the efficiency of the N fertilizer is through the enzymatic activity of the nitrate reductase (NR). This is a key enzyme in N assimilation, whose activity is regulated by a number of endogenous and exogenous factors that determine yield. The aim of this study was to assess the effect of N fertilization… More >
