Abstract:
In this study，oriental double-flower lily named ‘Belonica’ was used as experimental material.Strain of ACC deaminase-containing PGPR was fertilized during cultivating of the double-flower lily.Under contrast of clear water by putting cutting lily into，related physiological indices were tested and analyzed，and the effect of cutting lily with fertilizing different strains of ACC deaminase-containing PGPR could be explored accordingly.The results showed that activities of SOD，POD and content of soluble protein were firstly increased but then decreased.Contents of malondialdehyde (MDA) and proline (Pro) were generally on the rise.Meanwhile，it was found that the production of MDA was slowed down in a certain extent during the post-treatment to double-lily with fertilizing different ACC deaminase-containing PGPR.Comprehensive comparison discovered that the effect of the strain BG on the preservation of double lily cutting flowers was the most obvious.Strain BG not only maintained the ornamental quality of cutting flowers，but also postponed its aging process effectively.
