[CBNPMP-Thématique] DormanceRésumé : 1 Using the data in a recently published seed bank database for north-west Europe, we describe how a species’ seed bank behaviour can be characterized by a single ‘longevity index’, and investigate how representative the information in the database is of the north-west European flora. We also test the hypotheses that seeds of short-lived species are more persistent than those of long-lived species, and long-lived seeds are characteristic of species living in disturbed habitats. 2 The data are not representative of the north-west European flora as a whole; they are a fair reflection of a research effort that has been largely directed towards grassland and arable weeds. Data for rare species, non-agricultural habitats in general and wetlands, rocky habitats and native woodland in particular, are scarce or absent. 3 Annuals and biennials almost always have more persistent seeds than related perennials, and this difference is most striking when, as in Anagallis arvensis and Aphanes arvensis, the short-lived species have moved well away from the ‘core’ habitat of the family. Confamilial monocarps and polycarps do not differ consistently in seed mass. 4 Gradients of habitat disturbance are accompanied by predictable changes in seed persistence, which are themselves often (but not always) accompanied by parallel shifts in seed size. These results suggest that increasing habitat disturbance (i.e. increasing density-independent mortality) always selects for increased seed persistence, confirming both theory and previous analyses. However, increased seed persistence is not always associated with reduced seed size. This is because persistence depends not only on seed size, but on other traits, many of them physiological. In many habitats the probability of seed burial is strongly linked to seed size and shape, but in arable habitats cultural practices have broken this link.

Titre : Seed size, shape and vertical distribution in the soil : indicators of seed longevity Type de document : Tiré à part de revue Auteurs : Renée Marlies Bekker (1967-) ; Jan Pouwel Bakker ; U Grandin ; R. Kalamees ; Per Milberg ; Peter Poschlod ; Ken Thompson (1954-) ; J.H. Willems Année de publication : 1998 Importance : 834-842 Langues : Anglais (eng) Résumé : 1.We investigated the vertical distribution of seeds in the soil, using data from ninestudies in five European countries. We discovered significant correlations betweenseed shape and distribution in the soil.2.The classification of the longevity of seeds of plant species has been improved bythe introduction of a ‘longevity index’, expressing on a continuous scale the mostrecent information on seed longevity represented as the proportion of non-transientseed bank records in the database of Thompson et al. (1997). Remarkably, no differ-ence in seed longevity was found if the index was based on direct observations onlywhen compared with the index based on the complete data set where indirect, ‘depth-derived’ observations were included.3.Seed longevity was best estimated using a multiple regression model with anintegrated measure of seed size and shape and depth distribution of seeds.4.The shape of seeds, known to be a consistent character of species, was shown to beconstant within species, whereas depth distribution of seeds was highly variableamong sites. This is consistent with the variability of seed longevity found in publishedseed bank data.
