Comparative Study on Lycopene Content of Different Watermelon

Lycopene content of 33 watermelons materials involved in different flesh color and ploid were determinated by Spectrophotometry in this experiment,the results showed that: lycopene content of the white flesh of watermelon was lowest,the highest content was dark red flesh,among white flesh,orange flesh,golden yellow flesh,pink flesh,red and dark red flesh of watermelon material,There was a positive correlation between lycopene content and flesh color.Lycopene content of S292,VS8-44 was relatively high in the diploid watermelon of dark red flesh,were respectively 6.372 mg/100g fresh weight and 6.350 mg/100g fresh weight,The highest lycopene content of VS6-19 in the triploid watermelon was 6.684 mg/100g fresh weight.In the different materials,the lycopene content of the same flesh color was irrelevant to ploidy,related to Genotype of meterials.
