Amyloids of Plant Seeds

Abstract

USING the staining of cell-walls blue by an iodine in potassium iodide solution (0.3 gm. iodine and 1.6 gm. potassium iodide dissolved in 100 ml. water¹), many plant species previously designated as containing amyloid in their seeds⁶ (for example, of the genera Iris, Polygonatum, Narcissus, Hydrophyllum) are excluded, while others show the amyloid reaction with this reagent. The species of the latter group are summarized in Table 1.
