According to Csontos (2001), seed bank consists of all the naturally occurring seeds that are independent from their mother plants’ metabolism and either able to germinate or able to acquire this ability in the future. Several classification systems have been proposed for seed bank types, but Thompson’s system (Thompson 1992) is the most well-known and most accepted of them. Thompson described three categories based on the ability of a species’ seeds to remain viable in the soil: (i) transient seed bank – seeds remain viable for less than one year, (ii) short-term persistent seed bank – seeds remain viable for more than one year, but less than 5 years, and (iii) long-term persistent seed bank – seeds remain viable for more than 5 years. However, the boundary between the first two categories is often not evident and difficult to detect (Thompson et al. 1993), so in our database we aim to distinguish only between transient (0) and persistent (1) seed banks.

To avoid the confounding effect of different climatic and environmental conditions in general, seed bank type data presented here are all based on the results of studies carried out in Hungary. Based on the data of Csontos (2001), Csontos et al. (2016), Török (2008), Valkó et al. (2014) and Tóth (2015), we express the ratio of data indicating a persistent soil seed bank with a value from 0 to 1, where zero means that all available data indicates a transient seed bank, and 1 means that all available data indicates a persistent seed bank.

When using only the persistence rate calculated from published data of several sources, only the PADAPT database should be cited. When using specific published seed bank data, the data source(s) should also be cited.
