Abstract

We present the first inventory of the segetal flora of Italian winter cereal crops and allied crop types. The database consists of over 30,000 records, derived from different sources. We provide information and analyses on life forms, chorotypes, Ellenberg indicator values and preferential habitats of the flora. The inventory includes 987 vascular taxa and nothotaxa (868 species, 118 subspecies and 1 nothosubspecies), belonging to 354 genera and 55 families. Characteristic segetal species are 128, while 740 are generalist or accidental species from other habitats. Species exclusive of segetal habitats are 47. One species is extinct, and one is not confirmed in Italy. We recorded 42 neophytes, 15 archaeophytes and 10 cryptogenic species. Segetal species that are threatened in Europe are 45. Species in the Italian Red List are four, and five are threatened endemic species. The most frequent species are Papaver rhoeas (1,045 records), Convolvulus arvensis (623) and Ranunculus arvensis (571). Most species are therophytes (64%) and have a Mediterranean (36%), wide (14%) or eastern (13%) distribution range. Mean Ellenberg indicator values revealed relevant ecological affinities between the inventoried flora and cultivated winter cereals. Our work represents the basis for future applied studies in botany, ecology and agronomy.

摘要

我们介绍了意大利冬季谷物作物和相关作物类型的植物区系的第一个清单。该数据库包含来自不同来源的30,000多个记录。我们提供有关生命形式，染色体型，Ellenberg指标值和植物区系优先栖息地的信息和分析。清单包括987种维管类群和非类群（868种，118个亚种和1个非亚种），属于354属和55科。特征性的物种有128种，而740种是来自其他栖息地的通才或偶然物种。不包括植物栖息地的物种有47种。一种已经灭绝，一种尚未在意大利确认。我们记录了42个新植物，15个古植物和10个隐源物种。在欧洲受到威胁的陆生物种有45种。在意大利红色名录中的物种有4种，五种是濒危特有物种。最常见的物种是虞美人（1045个记录），田旋花（623）和田野毛茛（571）。大多数种类是附生植物（64％），分布范围为地中海（36％），宽（14％）或东部（13％）。平均Ellenberg指标值揭示了清单植物区系和冬季谷物栽培之间的相关生态亲和力。我们的工作为今后在植物学，生态学和农学上的应用研究奠定了基础。
