Glucose Space of the Corn Scutellum


SLICES of the corn scutellum (Zea mays L., var. ‘Funks G-76’) do not accumulate glucose although they take up glucose from a glucose solution at an appreciable rate1. Our results indicate that the scutellum tissue contains an intracellular glucose space the glucose content of which is in equilibrium with the bathing solution. Glucose space is denned as the volume of tissue water necessary to contain the glucose of the tissue at the concentration of the bathing solution2.
