The grapevine is one of most widely perennial crops grown worldwide. As for other species displaying clusters of small fruits, the development of single berries within a bunch is asynchronous and heterogeneous. Because of this, the study of water and solute accumulation kinetics and balance at organ level cannot be directly extrapolated from samples of populations of fruits. In order to have an original and reliable dataset on the accumulation kinetics of the main solutes (primary and secondary metabolites and cations) and water, we analyzed fruits populations sorted according to their density and also individual berries from the onset of sugar importation to the end of phloem unloading. The studies were performed on a panel of varieties representing different metabolic contexts for the relationship between the import of organic and inorganic solutes and fruit growth, including genotypes able to import water at low fruit osmotic potential. These original data sets are suitable to revisit some aspects of the accumulation of main solutes and water in the grapevine fruit development and/or to perform comparative studies with other fleshy fruits.

葡萄是全球范围内种植最为广泛的多年生作物之一。对于其他结簇生小果实的物种而言，果串内单个浆果的发育进程呈现异步性与异质性。正因如此，针对器官水平的水分与溶质积累动力学及平衡开展的研究，无法直接通过果实群体样本进行外推。为获取一套关于主要溶质（初生代谢物、次生代谢物与阳离子）与水分积累动力学的原创可靠数据集，我们对按密度分选的果实群体，以及从糖分输入启动至韧皮部卸载结束阶段的单个浆果进行了分析。本研究依托一组涵盖不同代谢背景的品种展开，这些品种覆盖了有机与无机溶质输入与果实生长之间的关系相关研究，包含能够在果实低渗透势条件下吸收水分的基因型。该套原创数据集可用于重新探讨葡萄果实发育过程中主要溶质与水分积累的相关问题，亦可用于与其他肉质果实开展比较研究。
