decreased during storage (Table 5). The content of total phenols in
the anthurium cut
flowers spathe treated with preharvest GABA at
1 mM were higher than those in control
flowers (P < 0.01; Table 5).
Also, anthurium cut
flowers spathe treated with 1 and 5 mM GABA
at pre and postharvest, respectively, showed the higher PAL
enzyme activity (P < 0.05) and lower PPO enzyme activity
(P < 0.01) during the storage at 4 C (Tables 3 and 5).
3.5. DPPH scavenging activity
Anthurium cut
flowers spathe treated with 1 and 5 mM GABA at
pre and postharvest, respectively, exhibited higher DPPH scaveng-
ing activity during storage at 4 C
