| 英文摘要: |
| Citrus unshiu “Guoqing No.1” was used as material for elucidating the effect of Kloeckera apiculata suspension post-harvest treatment on preventing fruit decay during storage period. The result showed that K. apiculata preparation of 2×106CFU/mL (CFU, cloning forming unit) significantly reduced the development of decay caused by green mold, blue mold and stem rot, showing the same effect of carbendazim treatment after storage period of 100 days, and the disease incidence was controlled under 1%. The antagonist population was between 3.5×105CFU/mL and 1.7×107CFU/mL in citrus fruit, and increased 1.7×107CFU/mL after 40 days storage, and then stabilized for the remaining storage period. After storage at 5℃ for 100 days, K. apiculata strain 34-9 did not alter any quality parameters of fruit. During storage, the change of relative electrical conductivity (REC) showed a coordinate tendency with malondlaldehyde (MDA) content, which kept continuously growing from the beginning to the end of the storage. In the storage period of 25 days, the REC value and MDA content of the treatments were all significantly lower than those of water treatment, but had no obvious difference from those of carbendazim treatment. K. apiculata strain 34-9 had no effect on the enzyme activity of super oxide dismutase (SOD), but significantly improved peroxidase (POD) activity after 100 day storage. |
