Polyribosomes have been isolated from pear seeds which show a capacity for in vitro protein synthesis. Translational capacity increased during stratification with a peak after 13 days of stratification. This increase was greatly diminished in seeds which were incubated at 25°C (“warm stratification”). The peak in protein synthetic activity coincides with the period of stratification required for normal development of excised embryos.
