Light-Induced Fluorescence Transient (LIFT) datasets for durum wheat under progressive drought stress in the field

The Light-Induced Fluorescence Transient (LIFT) sensor was mounted on a manually pushed cart to retrieve chlorophyll fluorescence-based traits over multiple days in a large panel of durum wheat genotypes (> 220 elite accessions from the association mapping population ‘UNIBO-Durum Panel’ assembled at the University of Bologna, Italy) subjected to a progressive drought in replicated field trials over two growing seasons (2017/2018 and 2018/2019) in Maricopa, Arizona, USA, a semiarid desert environment. The photosynthetic performance of light-adapted plants was non-invasively measured at the canopy level (at a distance of 60 cm) by means of the operating efficiency of Photosystem II (Fq'/Fm') and the kinetics of electron transport beyond Qa measured by reoxidation rates (Fr1' and Fr2'). Herein, processed and cleaned datasets, as well as raw data for both growing seasons are made publicly available. The R scripts used for processing and cleaning these data are also available.
