activity of
flowers, which led to diminishing of membrane lipid
peroxidation. Increased DPPH scavenging activity was positively
correlated with chilling tolerance in cucumber (Kang and Saltveit,
2002). The present study suggested that GABA treatment stimulate
PAL activity, as well as the total phenols accumulation. The
accumulation of phenols can lead to an enhanced antioxidant
capacity, which may contribute to the chilling tolerance in
anthurium cut
flowers. Wang et al. (2014) reported that the GABA
treated banana fruits showed significantly higher antioxidant
capacity assayed by DPPH and FRAP, which may be due to higher
total phenols accumulation. Also, except of indirect effect on
enhancing the antioxidant capacity, GABA itself have ROS
scavenging activity and enhanced antioxidant capacity of banana
fruit under GABA treatment can be due to endogenous GABA
accumulation
