Herbaceous Peony Polyphenols Extend the Vase Life of Cut Flowers

Herbaceous peony is a potential material for cut flowers, but its short vase life seriously affects the development of herbaceous flowers industry. In this study, polyphenols were applied to extend and results indicated that 8% mass concentration increased superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) activities; soluble protein content flowers; effectively reduced malondialdehyde (MDA) content. Meanwhile, water balance value flowers. addition, observation microstructures blockage mainly caused by Aspergillus spp. at stem ends inhibited growth Additionally, aquaporin genes (AQPs), including three plasma membrane intrinsic (PlPIP1;2, PlPIP2;1, PlPIP2;2) one gene (PlNIP), isolated. PlPIP1;2, PlPIP2;2, which induced polyphenol treatment, had common effects on maintaining Therefore, can significantly these provide application theoretical reference in extending
