¹⁴C results obtained for the samples from Kalapodi, Lefkandi and Corinth with ceramic phase, laboratory number, material identification, context description, sample ID, ¹⁴C age in yr BP, calibrated ranges for ±1σ and ±2σ, and ‰ δ¹³C.

The samples are ordered according to the relative chronological sequence. LH IIIC: Late Helladic IIIC; SM: Sub-Mycenaean; EPG: Early Proto-Geometric; MPG: Middle Proto-Geometric; LPG: Late Proto-Geometric; SPG: Sub-Proto-Geometric; EG: Early Geometric; MG: Middle Geometric; LG: Late Geometric; *: the date is the average of multiple measurements on the same sample (the number of measurements is indicated between brackets); a: RTK6372 and RTK6373 are parts of the same assemblage of seeds, and therefore dates were averaged; b: RTK6374 and RTK6375 are parts of the same assemblage of seeds, and therefore dates were averaged. All the charred seeds come from clusters. References for published contexts are included within the “Context” column; all the other contexts are yet unpublished. δ13C values were obtained using an isotope ratio mass spectrometer.样本按照相对年代序列进行排序。各阶段缩写及对应全称如下： LH IIIC：迈锡尼晚期IIIC阶段（Late Helladic IIIC）；SM：后迈锡尼时期（Sub-Mycenaean）；EPG：早期原始几何陶时期（Early Proto-Geometric）；MPG：中期原始几何陶时期（Middle Proto-Geometric）；LPG：晚期原始几何陶时期（Late Proto-Geometric）；SPG：亚原始几何陶时期（Sub-Proto-Geometric）；EG：早期几何陶时期（Early Geometric）；MG：中期几何陶时期（Middle Geometric）；LG：晚期几何陶时期（Late Geometric）； *：该日期为同一样本多次测量结果的平均值，测量次数标注于括号内； a：RTK6372与RTK6373属于同一种子组合的组分，故对其测年结果取平均值； b：RTK6374与RTK6375属于同一种子组合的组分，故对其测年结果取平均值。 所有炭化种子均出土于遗存簇。已发表的出土背景相关参考文献收录于"Context（出土背景）"列中，其余出土背景尚未公开发表。δ13C值通过同位素比值质谱仪（isotope ratio mass spectrometer）测得。
