花果期遮阴对设施草莓果实品质的影响OA

In order to ascertain the effect of shading on strawberry fruit quality and explore its mecha-nism,this study systematically compared the effects of shading treatment on single fruit weight,fruit shape in-dex,and the contents of VC,anthocyanins,soluble solids and titriticable acid of four strawberry 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 a-bout 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.
