对烧焦植物残骸中硫同位素(δ34S)值的测量可能有助于了解作物生产的空间结构和生态。我们研究了炭化、施肥、氧化和厌氧土壤条件对现代谷物/豆类种子δ34S值的影响，并评估了化学前处理对烧焦的现代谷物/种子和考古植物谷物/种子δ34S值的影响。我们利用这些结果来解释新石器时代的考古植物学材料中的δ34S值。我们的结果表明，δ34S值可以可靠地保存在烧焦的谷物/种子中，但受到厌氧土壤条件的影响，这种影响取决于淹水时间与S同化的关系。
The measurement of sulphur isotope (δ34S) values in charred plant remains has the potential to inform understanding of the spatial configuration and ecology of crop production. We investigated the effects of charring, manuring, oxidation and anaerobic soil conditions on modern cereal grain/pulse seed δ34S values, and assessed the effect of chemical pre‐treatment on charred modern and archaeobotanical grain/seed δ34S values. We used these results to interpret δ34S values in archaeobotanical material from Neolithic Çatalhöyük. Our results suggest that δ34S values can be reliably preserved in charred grain/seeds but are subject to influence by anaerobic soil conditions, the effect depending on the timing of flooding in relation to S assimilation.
