Chromosome numbers and information on ploidy level are of great importance for better understanding of plant evolution and taxonomy but also for species identification. Technical developments in flow cytometry dramatically improved the measurement of genome size and triggered a renewed interest in chromosome numbers. Web-based portals make these kind of data accessible for a wide audience in both academia and citizen science. The specialised database of German plant chromosome counts and ploidy estimates comprises to date more than 14,000 records covering 52% of the German taxa. The database is accessed about 70 times per month and became an integral part of several more comprehensive initiatives. One example is the Rothmaler Flora of Germany, which now for the first time features chromosome data with verified origin from the region of interest. Another is the German plant information hub FloraWeb currently amended by several new data sources with the chromosome number database as a major component.
染色体数目和倍性水平的信息对于更好地理解植物进化和分类学具有重要意义，同时也有助于物种鉴定。流式细胞术的技术发展极大地提高了基因组大小的测量能力，并重新激发了人们对染色体数目的兴趣。基于网络的门户使这些数据可以供学术界和公民科学领域的广大受众使用。德国植物染色体计数和倍性估计的专业数据库目前包含超过 14000 条记录，涵盖了德国 52%的分类单元。该数据库每月被访问约 70 次，并且已成为几个更全面的计划的组成部分。其中一个例子是德国的 Rothmaler 植物区系，现在首次收录了来自感兴趣地区的经核实来源的染色体数据。另一个是德国植物信息中心 FloraWeb，目前正在由几个新的数据源进行修订，染色体数量数据库是主要组成部分。
