Effects of HT on disease development in ‘Kamei’ Satsuma mandarin fruit during storage at ambient temperature. 150 fruits were used for fungal infection. A uniform lesion (4 mm deep, 3 mm wide) was made at the equator of the fruit using a sterile nail. Aliquots of 20 μl suspension of Penicillium italicum at 1×105 spores ml–1 were inoculated into each wound site. After fungal inoculation, the incidence of disease in fruit was detected at 1, 2, 3, 4, 5, 6 and 7 days after Penicillium inoculation. Statistically significant differences analysis was conducted between HT and control pericarp during the same period using Student’s t-test. *: significant difference (P < 0.05). Mean values and SE bars are provided. A: Fruit status at 3 d after Penicillium inoculation; B: Disease incidence ratio; C: Fruit lesion diameter.
