Changes in carbohydrate contents in embryonic axes during imbibition

Carbohydrate content in embryonic axes isolated from dormant sunflower embryos before imbibition (dry), from embryos that were imbibed on water for 3 and 24 h at 10°C (H2O), and HCN-treated embryos (HCN) imbibed for 3 h in gaseous HCN and then transferred for 21 h on water at 10°C. Values are means of five replicates ± sd. nd, Nondetectable; DW, dry weight.
