The same letter in a column does not differ at 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.
