This article presents a palynological study conducted on adhesive materials obtained from both experimental and archaeological wooden sickles. The archaeological sickles, dating back to the Early Neolithic period, were recovered from the waterlogged site of La Marmotta, located near Lake Bracciano in Rome, Italy. Experimental harvesting was carried out on cereal crops using sickles purposefully made with a modern resinous material that closely replicates the original composition. This approach allowed us to retrieve palynological information consistent with and comparable to that observed on ancient tools. The study's results highlighted the excellent adhesiveness of these materials, capable of trapping and preserving micro-remains collected during harvesting practices. The discovery of -type and --type pollen grains confirmed the predominant use of these agricultural tools for cereal harvesting. Notably, one particular neolithic sickle, whose resin primarily retained -type pollen, stands out for its exclusive use in cutting herbaceous plants of potential medicinal interest. In parallel, the analysis of pollen content retained in modern cereal spikes confirmed their potential to provide information about the type of crop and, to some extent, the floristic component of the surrounding environment.

新石器时代粘合剂的花粉分析和比较实验考古学：La Marmotta（罗马布拉恰诺湖）的见解

本文介绍了对从实验和考古木镰刀中获得的粘合材料进行的孢粉学研究。这些考古镰刀的历史可以追溯到新石器时代早期，是在意大利罗马布拉恰诺湖附近的拉马尔莫塔的水淹地发现的。使用与原始成分非常相似的现代树脂材料制成的镰刀对谷类作物进行了实验收割。这种方法使我们能够检索与古代工具上观察到的一致且可比的孢粉学信息。该研究的结果强调了这些材料的优异粘附性，能够捕获和保存在收获过程中收集的微量残留物。 β型和β型花粉粒的发现证实了这些农业工具主要用于谷物收割。值得注意的是，一种特殊的新石器时代镰刀，其树脂主要保留β型花粉，因其专门用于切割具有潜在药用价值的草本植物而脱颖而出。与此同时，对现代谷物穗中保留的花粉含量的分析证实了它们有可能提供有关作物类型的信息，并在某种程度上提供有关周围环境的植物区系成分的信息。
