Characterization of fruits, seeds and seedlings of species of Clusiaceae from sandy coastal plains (restingas) of Rio de Janeiro State

Authorship SCIMAGO INSTITUTIONS RANKINGS

In this work we studied the morphology of fruits, seeds and seedlings of five species of Clusiaceae present in vegetation of sandy coastal plains (restinga) from the State of Rio de Janeiro. The fruits of the studied species have characteristics of zoochoric (Clusia fluminensis, C. lanceolata, C. criuva and Garcinia brasiliensis) and anemocoric dispersion (Kielmeyera membranacea). The newly collected seeds have high germination rates: C. fluminensis (100%), C. lanceolata (100%), C. criuva (99.2%), G. brasiliensis (90.45%) and K. membranacea (91%). Germination is phanerocotyledonar in C. fluminensis, C. lanceolata, C. criuva and K. membranacea and cryptocotyledonar in G. brasiliensis. Seedlings of Clusia species are frequently found in the natural habitat especially associated with species of Bromeliaceae, that act as nursery plants.
