The objective of the present work was to determine adequate substrates and temperatures for germination of the seeds of Eugenia uvalha Meng and Paivaea langsdorfii Berg. The tested substrates were: filter paper, sterilized sand and sterilized soil in the modes: upon paper, upon and inside sand, and upon and inside soil. The temperatures employed were 20, 25 and 30oC. The effects caused by the treatments on the quality of the seeds were evaluated by the production of normal seedlings and by the rate of seed germination. Among the substrates tested on the germination of the two species, which caused the least damage in their quality were: ?inside soil? for seeds of E. uvalha (uvaia) and P. langsdorfii (cambuci). ln general, the temperature of 30oC proportioned the higher number of normal seedlings in a shorter space of time, seeds, germination, substrate, temperature.
