-(Floristic composition and diaspore dispersal syndromes of shrubs and tree species in Parque Estadual Mata São Francisco, Paraná State, Brazil). The present study aimed to describe the floristics and strategies of propagule dispersal, as well as the types of fruits from woody species in a semi-deciduous forest fragment, at Parque Estadual Mata São Francisco, which had suffered selective logging and became a conservation area in 1994. The survey was conducted monthly from October/2007 to July/2009 considering shrubs and woody individuals with DBH ≥ 5 cm, resulting in the identification of 99 species and 77 genera distributed in 36 botanical families among the dispersion syndromes, zoochory was the most frequent, represented by 64% of the species, followed by anemochory (23%), and autocory (13%). The most abundant fruit was the capsule type. Comparisions with a previous study made in the same area, highlighted an increase of richness, high turnover of species and higher proportion of dispersed animal species, suggesting a successional advancement of this fragment. Key words: Atlantic Forest, semi-deciduous seasonal forest, southern Brazil, zoochorics species RESUMO -(Florística e síndromes de dispersão de espécies arbustivo-arbóreas no Parque Estadual Mata São Francisco, PR, Brasil). O presente estudo teve por objetivos descrever a florística e as estratégias de dispersão de propágulos, assim como os tipos de frutos das espécies arbustivo-arbóreas em um fragmento de Floresta Estacional, no Parque Estadual Mata São Francisco, onde ocorreu extração seletiva de madeira até se tornar Unidade de Conservação em 1994. O levantamento florístico foi realizado durante os meses de outubro/2007 a julho/2009, considerando os indivíduos arbustivos e arbóreos com DAP ≥ 5 cm, resultando na identificação de 99 espécies e 77 gêneros, distribuídos em 36 famílias botânicas. A síndrome de dispersão mais frequente foi a zoocoria com 64% das espécies, seguida pela anemocoria (23%), e autocoria (13%); e o fruto mais abundante foi do tipo cápsula. As comparações com estudo anterior desenvolvido na área, ressaltaram o aumento na riqueza, grande substituição de espécies e maior proporção de espécies zoocóricas, sugerindo o avanço sucessional desse fragmento.
