摘要

This study aimed to reconstruct the environmental conditions and the crop management practices and plant characteristics when agriculture appeared in western Europe. We analyzed oak charcoal and a large number of cereal caryopsides recovered from La Peninsula. The carbon isotope discrimination (013C) values of oak, the dominant forest species in the region, indicates prevalence of a wet climate at the site. Further, we reconstructed crop management conditions, achievable yield, and crop characteristics and the reconstructed weight of wheat and barley caryopsides, following protocols of these parameters with present- day organic agriculture in the region. In parallel, a regional perspective was achieved through the study of wheat and barley grains of sevthan small- garden cultivation, a more extensive agriculture was practiced under good that grain weight and spike morphology were comparable to contemporary cereals.
