·Silicon Si in plant tissues reduces abiotic and biotic stress but it is incorporated as silica SiO2 which is difficult to solubilize for analysis We modified an oven induced tissue digestion and analysis method to improve Si solubilization and validated its accuracy by quantifying the mass balance recovery of Si from the hydroponic solution and plant tissues of
·The diamond grinding wheel on the grinding head usually a cup wheel or a cylindrical wheel rotates at a high speed and feeds transversely opposite to the periphery of the silicon ingot and either the ingot or the grinding wheel moves in a reciprocating manner along the central axis of the worktable to perform the grinding
