【Abstract】 In order to investigate Vc and lycopene contents in different parts of watermelons fruit, 7 triploid seedless watermelon cultivars includes 6 red and 1 yellow have been sampled to determine their total ascorbic acid(TAA),ascorbic acid(AA),dehydroascorbic acid(DHAA) and lycopene contents.3 red uncut seedless watermelon cultivars have been determined their TAA,AA,DHAA and lycopene contents after 2 months at room temperature.The results showed that TAA,AA,DHAA and lycopene contents were significantly diversity among different cultivars and different parts of seedless watermelon fruits,and the TAA,AA,DHAA and lycopene contents in the central of watermelon fruit was higher than that of near skin,TAA,DHAA and lycopene contents correlation were significant at the 0.01 level,AA and DHAA contents correlation were significant at the 0.05 level.The loss percentages of TAA,AA,DHAA and lycopene contents were also difference in uncut seedless watermelons after 2 months at room temperature.TAA,AA and DHAA and lycopene contents of the uncut seedless watermelons loss 20～50%after 2 months at room temperature.更多还原
