THE EXUDATION OF GLUTAMINE FROM LAWN GRASS

Abstract

In 1934 GREENHILL and CHIrBNALL (3) reported the exudation of gluta- mine from perennial rye grass when treated with nutrient solutions high in ammonia. This is the first recorded observation of glutamine being exuded from a plant. FIG. 1. Lawn grass, showing exuded salt, composed largely of glutamine. This salt was confined to the area fertilized, and the paths of the fertilizer spreader are clearly seen.
