REQUIREMENTS FOR GERMINATION

OXYGEN

❑ Oxygen in the presence of enough moisture causes respiration to start metabolism.

❑ This creates energy for the germination process.

❑ Respiration rates for germinating seeds are very high, therefore adequate oxygen is
necessary.

❑ The germination percent of most seeds will be retarded if oxygen percent goes below 20%

❑ Seeds beds that are over –watered or poorly drained will cause the oxygen supply to become

limited, so the germination percent will diminishw
