Summary
Embryonic axes of hazel seeds sown on GA3 (non-dormant) show a higher rate of protein synthesis than those of seeds sown on water (dormant). Associated with this increased protein synthesis are changes in tRNA and aminoacyl-tRNA synthetases. These changes appear to be consequences of changes at the transcriptional level which have previously been described.
