Foliar application of amino acid biostimulants increased growth and antioxidant activity of Epipremnum aureum

Abstract

The surge in demand for ornamental crops necessitates a more efficient and accurate fertilization regimen, attributed to their high nutritional requirements and vigorous growth. However, there is limited research exploring the response of Epipremnum aureum on Foliar-applied amino acid biostimulants, which can potentially improve the growth and antioxidant properties of these Epipremnum aureum. To address this gap, an indoor pot experiment was conducted, encompassing six treatments that varied in the concentration of applied amino acid biostimulants: 0.00% (T0), 0.04% (T1), 0.06% (T2), 0.08% (T3), 0.10% (T4), and 0.20% (T5). The results showed that the 0.08% concentration significantly increased peroxidase activity by 72.76%. Moreover, the 0.10% concentration increased chlorophyll content, catalase activity, dry mass, and total antioxidant capacity by 44.41%, 69.55%, 2.04-fold and 3.38-fold, respectively. Additionally, the 0.20% concentration significantly increased soluble sugar content by 52.32%. In conclusion, leaf-applied amino acid biostimulants significantly improved the yield and quality of Epipremnum aureum, with the optimal application concentration being 0.10%. These amino acid biostimulants, serving as efficient and non-toxic fertilizers, exhibit promising prospects for widespread application in agricultural production.
