摘要：

Many species have the seed analysis method described in rules for seed testing, however some Brazilian native species do not have studies related about germination methods. The aims of this study were characterize the size of Parkia multijuga Benth. seeds and determine the substrate and temperature for the germination test. The sizes assessed were the length, the width and the thickness. To indicate the best temperature and substrate for the germination test the completely randomized design was used in factorial (two substrate, between sand and between paper, and four temperatures, 20, 25 and 30 degrees C with light and 25-30 degrees C, with alternated light). Parkia multijuga seeds are ellipsoids shape and its mean size is 46.4 x 11.8 x 8.8 mm. The germination is hypogeal and cryptocotylar. The germination test should be made either 25 degrees C or 30 degrees C using sand as substrate, in continuous light condition.
