Abstract
Germination of non-dormant peanut seeds is characterized by a “climacteric-like” pattern in ethylene production. Treatment with ethylene resulted in the autocatalytic stimulation of ethylene synthesis, accompanied by an acceleration in the rate of germination. It appears that the availability of ACC could be limiting during the initial phases of the germination process. An increase in the conversion of ACC to ethylene during germination suggest an increase in EFE activity of the seeds. Continuous application of 100 µM octanoic acid during the germination period resulted in the inhibition of seed germination. However, a brief treatment with 1 to 100 µM octanoic acid resulted in the stimulation of germination due to an increase in the sensitivity of the seed tissue to ethylene.
