The Growth and Yield of Corn. II. Daily Growth of Corn Kernels¹

Abstract

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.

Effects of Sowing Date on Physiological Characteristics, Yield and Yield Components for Different Maize (Zea mays L.) Hybrids

“…Shorter cultivars had greater assimilated allocation to the grain than the taller cultivars (Benga et al, 2000). Grain growth rate is directly associated with dominant temperature and largely independent of dry matter accumulation in final crop (Duncan et al, 1965). If kernel growth outruns dry matter accumulation in the final crop, its required dry matter will be supplied and remobilized from stalks, leaves and cob covers (mostly from stalks).…”

Corn yield response to moisture stress and foliar fertilizer during grain fill

“…They point out that in addition to failure in fertilization, young ovules may abort within a week or two after fertil ization. After this period, dry matter accumulates at a relatively con stant rate (Duncan et al, 1965). Similar observations are stated by Hanway (1963Hanway ( , 1971.…”

“…There is a positive correlation between temperature and the rate of grain growth (Duncan et al, 1965).…”
