Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Riparian forests suffered from forest fragmentation, which in turn promote the change in the pattern of seed dispersion and modification of soil seed bank. The aim of this study is to indicate the main species that make up the seed bank of a stretch of riparian forest of the Mogi Guaçu River continued to a fragment of semidecidual forest, located in the Guarnição da Aeronáutica de Pirassununga. It was delimited ten plots of 10 x 10 m. Four soil samples was collected by plot with a 25 x 25 cm template. Samples were packed in greenhouse for seed germination and monitored every 15 days for six months. Altogether, 494 individuals from 19 families were sampled, distributed in 30 genera and 40 morphospecies. Diversity and distribution of species in the fragment is homogeneous and can be used as source of propagules for forest restoration.
RESUMO
Florestas ripárias sofrem com a fragmentação florestal, que promove mudanças no padrão de dispersão de sementes e modificação do banco de sementes. O objetivo do presente estudo é indicar as principais espécies que compõem o banco de semntes de um trecho de floresta ripária do Rio Mogi Guaçu River contínuo a um fragmento de floresta estacional, localizada na Guarnição da Aeronáutica de Pirassununga. Foram delimitadas dez parcelas de 10 x 10 m. Quatro amostras de solo foram coletadas através de um molde de 25 x 25 cm. Amostras foram mantidas em estufa para germinação de sementes e monitoradas a cada 15 dias por seis meses. Ao todo, 494 indivíduos pertencentes a 19 famílias foram amostrados, distribuídos em 30 gêneros e 40 morfoespécies. A diversidade e a distribuição das espécies no fragmento é homogênea, podendo ser usado como uma fonte de propágulos para restauração florestal.
