Subject(s): In: Plant and Soil Dordrecht (Netherlands) : Springer, 1975. v. 42, no. 2, p. 491-494Summary: A direct method of estimation of silica in rice plant tissues is reported. This involves the digestion of finely ground plant samples with concentrated nitric acid in corning-glass conical flasks followed by dissolution in Na2CO3 in stainless-steel beakers; the plant silica is thereby converted into molybdenum reactive form which is estimated colorimetrically. This method represents an improvement over the time consuming fusion procedure followed ordinarily and also dispenses with use of platinumware.
