摘要 Strawberry is an economically valuable crop all over the word. Its fruits contain large amounts of polyphenol compounds, anthocyanins for instance. Anthocyanins play important roles in attracting pollinators and protecting plants from various stresses. ANS （Anthocyanidin synthase） catalyzes the conversion of leucoanthocyanidins to colored anthocyanidins. In this study, the total anthocyanins concentration at seven developmental stages of the strawberry fruit were investigated by UV spectrophotometry at 496 nm and 700 rim; and the expression levels of the Fa-ANS gene were studied by qRT-PCR. The results showed that the anthocyanins contents gradually increased along with the fruit maturation; while the expression patterns of Fa-ANS were consistent with the anthocyanins.
