    Coexistence of multiple leaf nutrient resorption strategies in urban forests by Pin Li, Zejin Wang, Kun Ran

    Published 2025-01-01
    “…The resorption activity of evergreen needle-leaf trees and ectomycorrhizal trees was found to primarily rely on stoichiometric control rather than nutrient limitation, whereas stoichiometry and nutrient limitation control strategies were both employed by deciduous broadleaf trees and arbuscular mycorrhizal trees, supporting their ability to adapt to changing environmental nutrient availability. …”

    The Regulatory Effect of Se-Cd Interaction on Tea Plants (<i>Camellia sinensis</i> (L.) O. Kuntze) Under Cadmium Stress by Yanyun Sun, Yueling Zhao, Hongyu Zhou, Faxing Li, Yuanyuan Wang, Xiao Du

    Published 2025-01-01
    “…The findings are as follows: (1) Cd stress notably elevated the electrical conductivity, MDA content, and proline content of tea plants, whereas the Cd + Se<sub>1</sub> treatment significantly reduced the MDA and proline content under Cd stress; (2) the Cd stress treatment significantly increased the content of peroxides in the tea tree leaves and significantly decreased the activities of four antioxidant enzymes, SOD, POD, CAT, and Apx; the Cd + Se treatment significantly reduced the peroxide content in tea trees under cadmium stress and significantly increased the activities of SOD, POD, CAT, and Apx; (3) the Cd stress treatment significantly increased the values of certain chlorophyll fluorescence parameters and had no significant impact on the distribution of light energy, whereas the Cd + Se treatment significantly elevated the values of some chlorophyll fluorescence parameters and induced an uneven distribution of light energy; (4) the order of accumulation of Cd in different organs of the tea plants was as follows: root > stem > leaf, and the Cd + Se treatment significantly reduced the Cd content in various organs under Cd stress. …”
