In order to identify new crops in the 1st millennium ce in northern Italy, a complex and diversified territory, archaeobotanical macroremains from 155 sites dating between the 2nd century bce and 12th century ce were analysed. In more than half of the sites, taxa were encountered that had never previously been recorded from the area. The new crops are about 30, mainly (~ 70%) fruit plants in the broad sense, which have a clear peak in this time period. Based on the available data, the most prominent time for the introduction of new food plants (both imports and cultivars) seems to have been the Roman Imperial period (1st–2nd century ce), but also later, in Late Antiquity (3rd–6th century ce) and the Middle Ages (7th–12 century ce), there was no lack of new arrivals. Some fruit trees, such as Prunus persica (peach) and Pinus pinea (stone pine) immediately played an important role, and have continued to do so over time, as these are still grown in the area now.

为了确定意大利北部这一复杂而多样化的地区在公元 1 世纪出现的新作物，我们对 155 个遗址的公元前2 世纪至公元12 世纪期间的大型考古植物遗迹进行了分析。在超过一半的地点，遇到了该地区以前从未记录过的类群。新作物约30种，主要是广义的果类植物（~70%），在这一时期有明显的高峰。根据现有数据，引入新食用植物（包括进口植物和栽培品种）的最显着时期似乎是罗马帝国时期（公元 1 世纪至 2 世纪），但也包括更晚的古代晚期（公元 3 世纪至 6世纪）公元世纪）和中世纪（公元 7 世纪至 12 世纪），不乏新来者。一些果树，如桃树和石松，立即发挥了重要作用，并且随着时间的推移，这种作用继续发挥作用，因为这些树现在仍在该地区种植。
