Silicon via nutrient solution modulates deficient and sufficient manganese sugar and energy cane antioxidant systems

Abstract Manganese (Mn) is highly demanded by Poaceae, and its deficiency induces physiological and biochemical responses in plants. Silicon (Si), which is beneficial to plants under various stress conditions, may also play an important role in plants without stress. However, the physiological and n...
