Tris(1-aziridinyl)-phosphine Oxide inhibits the growth of seedling grasses with concomitant accumulation of anthocyanins and exudation of sap. Treated plants are deficient in cell-wall materials. However, the percentage of Other metabolic products, such as protein and simple sugars, is increased. We suggest that this compound inhibits cellular expansion by cross-linking with cellulose in the plant cell wall.
