Morphophysiological adaptations of common buckwheat to silicon application under salt stress

This dataset presents experimental data on the effects of foliar silicon application on the growth and photosynthetic efficiency of common buckwheat (Fagopyrum esculentum cv. Smuga) under salt stress. The study was conducted at the Poznań University of Life Sciences, Poland, during the 2024 growing season. Buckwheat plants were subjected to 50 mM NaCl stress, and a foliar spray of a 1 mM sodium metasilicate nonahydrate (Na2SiO3·9H2O) solution was applied at a rate equivalent to 400 L ha⁻¹. The dataset includes the following files: Morphology.xlsx- contains data on growth attributes, including root and shoot length, leaf number, leaf thickness, and fresh and dry weights of roots and shoots. OJIP Curve.xlsx- provides chlorophyll a fluorescence (OJIP) transients of dark-adapted plants, recorded using a FluorPen FP 110/D instrument. OJIP Parameters.xlsx- includes various chlorophyll fluorescence parameters derived from OJIP transients. Photosynq Parameters.xlsx- contains photosynthetic parameters based on fluorescence and electrochromic shifts, measured using a MultispeQ V2.0 device connected to the PhotosynQ platform. Temperature.xlsx and PAR.xlsx- provide temperature and photosynthetic photon flux density (PPFD) data from the growing season during the experiment. This dataset is valuable for researchers studying abiotic stress tolerance mechanisms in plants.
