When anthurium cut flowers, endemic to tropical climates, are
stored at 4 ◦C, (1) phenylalanine ammonia-lyase (PAL) enzyme
activity increased due to the chilling lead to accumulation of phenols
in vacuoles; (2) electrolyte leakage and malondialdehyde
(MDA) content increased, which indicated membrane integrity
and selective permeability declined; (3) polyphenol oxidase (PPO)
enzyme activity as responsible for spathe browning increased; (4)
phenols accumulated in vacuoles leak to cytoplasm due to loss of
membrane integrity and contribute to spathe browning, observ-
