Epibrassinolide improves the growth performance of Sedum lineare upon Zn stress through boosting antioxidative capacities.

As an essential element, zinc (Zn) can improve or inhibit the growth of plants depending on its concentrations. In this study, the effects of 24-Epibrassinolide (EBR), one well-known steroid phytohormone regulating plant growth and alleviating abiotic stress damage, on morphological parameters and a...
