Silica And Ash In Several Marsh Plants, F.C. Lanning, Lionel N. Eleuterius
Gulf and Caribbean Research
Ash and silica content and their depositional patterns in tissues of Spartina alterniflora Loisel., Distichlis spicata (L.) Greene, Scirpus validus Vahl., Zizania aquatica L., and Limonium carolinianum (Walt.) Britt. were determined. Zizania aquatica leaves had the highest silica content (6.0%) of any of the plant parts tested; silica making up over half of the ash. Silica in the plants was opaline in character. Limonium carolinianum did not accumulate silica in any great amount. However, ash content was very high in Limonium carolinianum and Scirpus validus making up over 17% of the dry weight of the leaves. X-ray diffraction showed the …
