摘　　要：以14种不同品种的南瓜为材料,在果实成熟期采用CR-3型色差仪测量其叶片、花朵、果肉的Lab值,同时采用PAL-1型测糖仪测量果肉中可溶性固形物含量,并对叶、花、果肉的Lab值与果肉中可溶性固形物含量进行了相关性分析。结果表明,南瓜叶、花、果肉色泽的Lab值的变异系数有差异,果肉中红色成分变异系数最大,达27.43%;果肉中可溶性固形物含量与叶片的亮度呈极显著正相关(r=0.632),与果肉中红色成分呈显著正相关(r=0.412)。这为南瓜品质育种田间筛选可溶性固形物含量高的试验材料提供了便捷的方法。The colour values of leaf, flower, fruit sarcocarp by CR-3 eolorimeter and the soluble solids content （SSC） of fruit sarcocarp by the PAL-1 digital display sugar meter were measured for 14 pumpkin eultivars respectively in this experiment. The correlation between colour values of leaf, flower, fruit sarcocarp and SSC of fruit sareocarp were analyzed. The results showed that there were differences between the coefficient of variation of leaf, flower, fruit sarcocarp colour values, and fruit sarcoearp redness in the coefficient of variation was the largest （CV=27.43%）. SSC of fruit sarcocarp was highly significantly positive correlated （P〈0.01, r=0.632 ） with brightness of leaf, and it was significantly positive correlated （P〈0.05, r=0.412 ） with its redness. This Results provided a convenient method to screen high SSC of fruit sareocarp in the filed for pumpkin quality breeding.
