摘　　要：为了分析西瓜果实中番茄红素含量与栽培环境的关系,培育更具市场竞争力的优质西瓜品种,将80份西瓜材料的种子均分为2份,分别在河南新乡和新疆昌吉种植,待果实成熟后取果肉用高效液相色谱法(HPLC)测定番茄红素含量。结果显示,80份西瓜材料在河南新乡、新疆昌吉种植的平均番茄红素质量分数分别是20.84、28.53 mg·kg^(-1);总体水平上,新疆昌吉栽培条件下番茄红素含量高于河南新乡;不同材料间番茄红素含量差异较大,栽培环境和基因型共同影响西瓜番茄红素含量。Producers of fresh fruits and vegetables face increasing production costs and international market competition. Growers who can offer high-quality watermelons [Citrullus lanatus （Thunb.） Matsum. ＆ Nakai] with high nutrition will have better market opportunities. To accomplish this goal, germplasm must be id6ntified that has enhanced phytonutrient levels. The present study was performed on 80 watermelon materials by high performance liquid chromatography （HPLC） to determine the importance of genotype and environmental effects on lycopene concentration, a carotenoid which has antioxidant properties that may reduce the incidence of certain cancers. Our results demonstrated that lycopene concentration was affected by both genotype and environment, and the amount of environmental effect varies among cuhivars. The mean of fruit tested was 20.84 mg-kg-L in Xinxiang and 28.53 mg＇kg-~ in Xinjiang. In general,the watermelon contents in Xinjiang were found higher than that in Xinxiang, and the difference of lycopene contents were larger within different materials, the lycopene contents in watermelon fruits were effected by both genotype and environment.
