Calcium peroxide as a seed coating material for padi rice

I. Requirement for and provision of oxygen
  • Ann M. Baker
  • William Hatton


Measurement of oxygen uptake by germinating rice seed (Oryza sativa L) suggests that oxygen requirement is independent of temperature of incubation. However, the rate of oxygen consumption is dependent upon incubation temperature and, after an initial lag phase, is exponential with time.

Although rice seed can germinate and grow at low oxygen concentrations, germination is poor and seedlings exhibit low vigour. An oxidized zone may be observed around the seed when sown in an anoxic environment but coated with a layer of calcium peroxide. The seed germinates readily and develops normally when a sufficient level of calcium peroxide is used.
