Comparison of sugar levels for kernels isolated from field grown maize (B73) from the 2012 and 2103 growing seasons. Control kernels on continuous sucrose feeding are indicated with closed (black) squares, and sucrose-starved kernels are indicated with open (white) squares. The shaded area of the graph indicates the starvation period, and the unshaded region represents the recovery stage when starved kernels were allowed to recover on sucrose-enriched medium. The initial time point (T = 0) is from after kernel sterilization
