A dataset of physiological parameters and 13 plant endogenous hormone concentrations with root restriction in 2019-2020

Abstract

Root restriction, as an efficient cultivation method, has been widely used to promote grapes fruit quality. In China, root restriction cultivation is usually implemented in the production of table grape berries to get higher yield planting in hot and humid environment. It is well known that endogenous plant hormones play an important role in plant growth and development, flowering and ripening, but the effect of root restriction on endogenous plant hormone contents in grape is still unclear. Therefore, it is very important to build a database of grape endogenous hormone contents with root restriction treatment. These data not only provide a reference for the analysis of fruit quality under root restriction, but also lay a theoretical foundation for the variation tendency of grape endogenous hormone contents. In this study, a total of 84 samples (3 biological replicates) were collected from different tissues and organs in different developmental stages of ‘Muscat Hamburg’ grape and analyzed by high performance liquid chromatography (HPLC). Thirteen endogenous plant hormones were identified and a comprehensive dataset of endogenous plant hormones in different organs and developmental stages of ‘Muscat Hamburg’ grape was established. The results provided data support for rapid detection and quantitative analysis of endogenous plant hormones in grape under root restriction cultivation.
