High-resolution time-series data of carotenoid pools, fluorescence and absorbance dynamics in tree leaves during sudden high-light exposure

This dataset contains raw and processed data used in the study investigating second-scale pigment and fluorescence dynamics during sudden high-light transitions in three woody plant species (Celtis australis, Morus alba, and Quercus ilex), grown under contrasting light conditions (sun vs. shade). The goal of the study was to understand how carotenoid pool dynamics, particularly in the α- and β-branches, contribute to rapid non-photochemical quenching (NPQ) and photoprotection mechanisms.Leaves from sun- and shade-grown branches of the three species were dark-adapted and then subjected to sudden high-light exposure (1000 μmol m⁻² s⁻¹) in a controlled laboratory setting.本数据集包含一项研究所用的原始与经处理数据，该研究旨在探究3种木本植物——欧洲朴树（*Celtis australis*）、白桑（*Morus alba*）与冬青栎（*Quercus ilex*）——在不同光照条件（阳生与阴生）下遭遇突发强光转换时的秒级色素与荧光动力学变化。本研究的核心目标为阐明类胡萝卜素库动力学，尤其是其α与β分支，如何参与快速非光化学淬灭(NPQ)及光保护机制。研究人员将取自上述3种植物阳生及阴生枝条的叶片进行暗适应处理，随后在可控实验室环境中使其暴露于强度为1000 μmol·m⁻²·s⁻¹的突发强光照射之下。
