Synopsis

Synopsis

Under the conditions of this experiment the stalk was an important storage organ for sugar which, under some conditions, can be translocated to maintain dry weight growth of the kernels for extended periods in the absence of photosynthesis. It seems probable that sugar storage in the stalk provides most of the reservoir of readily mobile sucrose required to maintain relatively uniform kernel growth in spite of wide diurnal and day-to-day variation in photosynthesis.
