WitrynaSeed Imbibition. Germination begins when a seed is given water and the temperature is appropriate for non-dormant seeds. Imbibition is the process of a dry seed absorbing water (imbibition means to drink: seeds imbibe water, you do not imbibe seeds). Seeds expand as they drink water, hydrating enzymes and food supplies. Witrynawere inhibited in the mitochondria of the OsAOX1a-RNAi seeds after imbibition, indicating decrease in the ATP supply.
