Fig. 2.

Germination and ethylene production of dormant (D) and non-dormant (ND) dehulled red rice caryopses imbibed in water or in the presence of the ethylene precursor ACC. (A) Pericarp splitting (first visible stage of germination), (B) seedling growth stage S1, (C) rate of ethylene emission. In the inset, data are replotted with a more detailed scale of emission (y-axis) to evidence ethylene production from non-dormant caryopses incubated in water. Standard errors between independent experiments are shown (n = 3).
