Silica content of living rhizomes from the perennial salt marsh rush Juncus roemerianushad values of 0.34, 0.20, and 0.60% of dry weight in three morphologically distinct populations along the Mississippi coast and was directly related to available silica content of the soil (29.7, 17.0, 169.6 mg/100g soil, respectively). On the other hand, living leaves had about the same average silica content (0.93, 0.87, 0.9070 or dry weight). The silica content of living leaves varied from 0.142% in younger leaves to 1.520% in older ones. Similarly, rhizomes also increased in silica content with age, varying from 0.137% in younger portions …
