— To retain the normal balance of ROS levels under drought stress, plant tissues produce various enzymes that are scavengers of ROS (Mattos and Moretti 2015). Increased tolerance of abiotic stress in plants is thought to be associated with rapid detoxification of excessive ROS (Martinez et al. 2018 ).

So ball milling renders a solution more homogeneous by the milling action of the grinding media, the amount of charge in the mill, the speed of rotation in the mill, and the time the solution is in the mill being processed. There is an optimum balance between all these factors relative to the glaze.
