AbstractIn order to ascertain the eect of shading on strawberry fruit quality and explore its mechanism，this study systematically compared the effcts of shading treatment on single fruit weight，fruit shape index，and the contents of Vc，anthocyanins，soluble solidsand titriticable acid of four strawbery varieties （Zhangji，Xiangye，Yuexin and Yuehouji）.Transcriptome sequencing technology was used to analyze the effects of shading treatment on gene expression in Zhangji strawberry fruits.The results showed that shading about 36.9% in greenhouse decreased single fruit weight， increased fruit shape index，decreased the contents of Vc，anthocyanins and soluble solids，and increased the content of titriticable acid，with the most significant effect on the content of anthocyanins.Transcriptome sequencing analysis showed that the effects of shading treatment on strawberry fruits involved multiple physiological and biochemical processes as well as the synthesis and accumulation of secondary metabolites.
