研究目的
Investigating the antifungal effect of blue LED irradiation on the blue mold, Penicillium italicum, in satsuma mandarin fruits after harvesting.
研究成果
Blue LED irradiation significantly reduced the development of blue mold symptoms in satsuma mandarin fruits, both when applied after and before inoculation with Penicillium italicum, especially at low inoculum doses. The treatment did not adversely affect fruit quality, except for slight changes in citric acid concentration and moisture loss. These findings suggest that blue light irradiation can directly inhibit fungal growth and may induce an antifungal response in the fruits.
研究不足
The study focused on the effect of blue LED irradiation on Penicillium italicum in satsuma mandarin fruits under specific conditions. The applicability of the findings to other citrus varieties or pathogens was not explored. The practical implementation of blue LED irradiation in storage facilities may require adjustments based on the storage method and fruit arrangement.
1：Experimental Design and Method Selection:
The study investigated the effect of blue LED irradiation on Penicillium italicum in satsuma mandarin fruits. The experimental design included inoculation with Penicillium italicum followed by blue LED irradiation or dark treatment.
2：Sample Selection and Data Sources:
Satsuma mandarin fruits (Citrus unshiu Marc. 'Aoshima unshu') were used, harvested from the Shizuoka Prefectural Agriculture and Forestry Research Institute Fruit Tree Research Center.
3：List of Experimental Equipment and Materials:
Blue LED light (maximum emission wavelength 465 nm, 80 μmol?m-2?s-1), digital refractometer (PAL-1, Atago), colorimeter (TC-1500MC88, Tokyo Denshoku).
4：Experimental Procedures and Operational Workflow:
Fruits were inoculated with Penicillium italicum and then exposed to blue LED light or kept in darkness. The development of symptoms was observed and measured.
5：Data Analysis Methods:
The data were analyzed for significant differences using Tukey's multiple range test and t-test.
