The same letter in a column does not differ at P ≤ 0.05 by LSD; †(nonstructural carbohydrate (NSC) in stem at heading − NSC residue in stem at maturity) ÷ NSC in stem at heading × 100; ‡transfer ratio of total assimilates = (panicle dry matter at maturity − panicle dry matter at heading) ÷ [NSC in stem at heading + (plant dry matter at maturity − plant dry matter at heading)]; residue = the amount of NSC remaining in stem at maturity.
