Fig. 3.

Ratio of organ (leaf blade, sheath, internode, cob, tassel) fresh weight over above-ground fresh weight at three developmental stages (GC 8; GC 18, about silking; GC 30, maturity) during five seasons: (A) leaf blade and cob, means of four replications; (B) intenode, leaf sheath and tassel, means of four replications; (C) stacked, inter-annual means for five seasons. Labels in this graph refer to open spaces (differences) between lines. What appears to be a double line in (C) actually encloses the very small fraction of tassel biomass. Error bars indicate standard error of mean.
