Summary

THERE WAS AN ACCUMULATION OF TOTAL FREE AMINO ACIDS IN COROLLAS FROM CUT < SONIA > ROSES AT 275 K (2 DEG C),COLD-STORED FLOWERS, BUT NOT IN THOSE KEPT AT 293 K (20 DEG C), CONTROL FLOWERS. THERE APPEARED TO BE NO DIRECT CORRELATION BETWEEN SENESCENCE OF CUT ROSES AND ACCUMULATION OF TOTAL AMINO ACIDS IN COROLLAS ; NEITHER WAS THERE A RELATIONSHIP BETWEEN INDIVIDUAL OR TOTAL FREE AMINO ACIDS AND PROTEASE ACTIVITY FROM EITHER COLD-STORED OR CONTROL FLOWERS. CHANGES IN THE CONTENTS OF ALL FREE AMINO ACIDS, EXCEPT ALANINE AND LYSINE, WERE AFFECTED BY COLD STORAGE. THE EFFECT ON ASPARTIC ACID WAS STATISTICALLY SIGNIFICANT. COLD STORAGE DELAYED THE DECREASE IN CONTENTS OF GLUTAMIC ACID, ASPARAGINE, TYROSINE, GLYCINE, LEUCINE, ISOLEUCINE AND VALINE, AND PREVENTED ACCUMULATION OF PHENYLALANINE, PROLINE, AND HISTIDINE.
