Research of fruit quality for different Hami melon varieties

This experiment was conducted to analyze the differences of the fruit quality by measuring the appearance quality and nutrient quality of six different Hami melon varieties. And then assessed the fruit quality comprehensively by scoring method. The results showed that it had significant difference between different Hami melon varieties on weight per fruit, soluble solids, soluble sugar content, organic acid and sugar/acid ratio. The variation ranges of these five different parameters were between 1.11- 1.96 kg, 11.90%- 16.60%, 9.29%- 16.38%, 0.17%- 0.46% and 28.04- 77.23, respectively. The soluble solids content of all the varieties reached to over 14% except for Ximi17, and Fengwei5,Fengwei4 were two times than other varieties on organic acid; The soluble sugar contents of Fenwei5 and Ximi25 were higher than others, and sugar/acid ratio of Ximi25 was the highest of all. After principal component analysis, it showed that the main indicators affecting fruit quality were weight per fruit, sugar/acid ratio, water content, soluble solids, thickness of pulp and soluble sugar content. Comprehensively,the best taste was Ximi25, and its fruit was tender, crisp fragrant, honey sweet. Fengwei5 fruit size and sugar acid was medium. Both of Ximi25 and Fengwei5 fruits were better in nutritional quality. Baimei fruit was tender, honey sweet. They could be cultivated at the west of Guangdong.
