WHEAT SEED (<i>TRITICUM AESTIVUM</i> L.) RADIOCARBON CONCENTRATION OVER THE LAST 75 YEARS

ABSTRACT Here we report radiocarbon measurements made on wheat seed tissue ( Triticum aestivum L.; winter or spring type growth habit), from the archive of IPK Gatersleben, Sachsen-Anhalt, Germany, which was harvested between 1946 and 2020. The results give an overview 75 years concentration evolution in agricultural plant products. concentrations follow known pre- post-bomb records, such as atmospheric Jungfraujoch, Schauinsland, NH1 datasets. Based a Northern Hemisphere growing period April to July, Gatersleben indicates incorporation fossil carbon about 1% with respect high alpine, clean-air CO 2 Jungfraujoch station 1987 2019. We propose use record reference forensic investigations, age estimation paper by analyzing starch used manufacture. Additionally, advantage reported here lies its extensibility adding new analyses future harvests.
