EFFECT OF ETHYLENE TREATMENT OR COLD STORAGE ON CHANGES IN THE CONTENTS OF TOTAL AND INDIVIDUAL FREE AMINO ACIDS IN COROLLAS FROM CUT 'SONIA' ROSES
Hence there appeared to be no direct correlation between senescence of cut roses and accumulation of total free amino acids in the corollas.
We did not find a correlation between individual or total free amino acids and protease activity in the corollas of ethylene-treated, cold-stored or control flowers from the same batch.
Of the thirteen individual free amino acids that we determined, only leucine was clearly affected by the ethylene treatment. However changes in the contents of all free amino acids, except alanine and lysine, were affected by cold storage.
We detected only one theoretically expected interconversion between two amino acids: glutamic acid to proline, that occurred in corollas from control flowers during the first 6 days of storage.
