Abstract:

reproductive phenology, floral morphology and the reproductive system of schinus terebinthifolius were investigated in two physiognomies of restinga vegetation at grussai/iquipari, rio de janeiro, from january to december/2004. schinus terebinthifolius had cornucopia flowering strategy, with two flowering peaks during the year, both in the rainy season; fruit was set in the dry period. morphological analysis of the flowers and pollination experiments confirmed dioicism and obligatory xenogamy in this species. high synchrony between male and female plants occurred, an important strategy for dioecious species. no difference in fruit set was found between natural and cross pollinations in the two physiognomies studied, indicating lower values than those observed in others studies.
