| Popis: | By spraying the exogenous polyamine spermidine (Spd) and the polyamine biosynthesis inhibitor d-arginine (d-Arg) in cut Paeonia lactiflora flowers, the dynamic change of superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), soluble protein, endogenous polyamines and endogenous hormones were studied. The results showed that, the effect of exogenous polyamines and polyamine inhibitors could significantly affect the content of the vase life, which Spd decreased the vase life of flowers 1.4 days. d-Arg extended the vase life 1.8 days, improved the contents of soluble protein, activities of antioxidant enzymes, endogenous GA3, IAA, putrescine (Put), ZR and decreased the MDA content, endogenous ABA, Spd in cut herbaceous peony flowers. The effect of Spd and d-Arg might control the flower senescence through the way of affecting the hormones by affecting the endogenous polyamines or through the way of affecting the hormones and endogenous polyamines directly. |
