摘　　要：以9个不同萝卜品种为试材,运用模糊综合评价的方法分析评价了其抽薹特性,在此基础上鉴定出耐抽薹品种"白玉春"和易抽薹品种"满身红",并对其抽薹前后的生理生化特性进行了分析,以期为探查萝卜抽薹的生理机制提供参考依据。结果表明:可溶性糖、可溶性蛋白质含量和过氧化物酶(POD)、过氧化氢酶(CAT)及硝酸还原酶(NR)活性在抽薹前呈逐渐升高趋势,但抽薹后则逐渐下降。因此,这些生理指标与抽薹呈现正相关的关系。A fuzzy comprehensive evaluation was deployed to identify and evaluate the bolting of nine Raphanus sativus L. varieties, among which a bolting- resistant variety ＇Baiyuchun＇ and a bolting-sensitive variety ＇Manshenhong＇ were identified. Furthermore, several physiological characteristics were investigated between two varieties before and after bolting. The results showed that the contents of soluble sugar and proteins, as well as the activities of POD,CAT and NR increased steadily before bolting and reached the maximum level at the time of bolting, whereas decreased after bolting. The data suggested that those physiological characteristics were highly associated with bolting of radish.
