Carbon-14 Distribution in Carbohydrates of Immature Zea mays. Kernels Following ¹⁴CO₂ Treatment of Intact Plants ¹

Shortly after Zea mays L. plants were exposed to ¹⁴CO₂, most of the radioactivity in the kernel occurred in the free monosaccharides, glucose and fructose. Later the proportion of ¹⁴C in sucrose increased and that in the monosaccharides declined. These data have been interpreted as showing that the translocated sugar is hydrolyzed prior to or during its movement into the storage cells of the endosperm. This hydrolysis appears to occur in the "pedicel region" of the kernel. After entry into the endosperm tissue, sucrose was rapidly resynthesized from the monosaccharides prior to its utilization in starch synthesis.
