    Comprehensive Assessment of the Safety of Eucommia ulmoides Leaf Extract for Consumption as a Traditional Chinese Health Food

    Huiling Fu1, Mijun Peng2, Qiuwen Tang2, Haojun Liang2, Yanli Liang2, Jiali Fang2,*, Xuesong Wang2,*

    Journal of Renewable Materials, Vol.11, No.7, pp. 3091-3114, 2023, DOI:10.32604/jrm.2023.026689

    Abstract To ensure the export quality of Eucommia ulmoides leaf extract (ELE) and facilitate E. ulmoides leaf inclusion in the directory of traditional Chinese health foods, an overall safety assessment of ELE was performed, including genotoxicity and long-term toxicity, according to the national food safety standards of China. No variations in the reverse mutation number of the nominal bacterial strains were observed under ELE treatment in comparison with the solvent control. Additionally, the micronucleus rates of in vivo mammalian erythrocytes and in vitro mammalian cells under ELE treatment were equivalent to or significantly lower than those of the solvent control.

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1513-1537, 2023, DOI:10.32604/phyton.2023.025175

    Abstract Drought is a severe environmental constraint, causing a significant reduction in crop productivity across the world. Salicylic acid (SA) is an important plant growth regulator that helps plants cope with the adverse effects induced by various abiotic stresses. The current study investigated the potential effects of SA on drought tolerance efficacy in two barley (Hordeum vulgare) genotypes, namely BARI barley 5 and BARI barley 7. Ten-day-old barley seedlings were exposed to drought stress by maintaining 7.5% soil moisture content in the absence or presence of 0.5, 1.0 and 1.5 mM SA. Drought exposure led to severe damage to both genotypes,… More >

    Foliar Application of Cytokinin Modulates Gas Exchange Features, Water Relation and Biochemical Responses to Improve Growth Performance of Maize under Drought Stress

    M. Rafiqul Islam1,*, M. Shahinur Islam1, Nurunnaher Akter1, Mohammed Mohi-Ud-Din2, Mohammad Golam Mostofa3,4,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 633-649, 2022, DOI:10.32604/phyton.2022.018074

    Abstract Improvement of plant performance under drought stress is crucial to sustaining agricultural productivity. The current study investigated the ameliorative effects of foliar-applied kinetin, an adenine-type cytokinin (CK), on growth and gas exchange parameters, water relations and biochemical attributes of maize plants under drought stress. Eighteen-day-old maize plants were subjected to drought by maintaining soil moisture content at 25% field capacity for 8 days followed by foliar application of kinetin at 0, 75, 150 and 225 mg L−1 (CK0, CK75, CK150 and CK225, respectively) to the plants for two-times at the 9-day interval. Results revealed that drought stress markedly reduced stem diameter,… More >

    Differential Effects of Ammonium and Nitrate on Growth Performance of Glechoma longituba under Heterogeneous Cd Stress

    Yanwei Feng1, Wen Lei2, Rui Gu3, Ping Zhao4, Shijun Ni1,*, Ningfei Lei3,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 667-679, 2020, DOI:10.32604/phyton.2020.010160

    Abstract Water, minerals, nutrients, etc., can be shared by physiological integration among inter-connected ramets of clonal plants. Nitrogen plays an important role in alleviating cadmium (Cd) stress for clonal plants. But how different forms of nitrogen affect growth performance of clonal plants subjected to heterogeneous Cd stress still remains poorly understood. A pot experiment was conducted to investigate the differential effects of ammonium and nitrate on growth performance of Glechoma longituba under heterogeneous Cd stress. In the experiment, parent ramets of Glechoma longituba clonal fragments were respectively supplied with modified Hoagland solution containing 7.5 mM ammonium, 7.5 mM nitrate or the… More >
