Summary

This paper presents information about the germination of the seeds of araçá-pera (Psidium acutangulum D.C.), at the same time comparing the effect of different substrates: sand, loam and sawdust. The statistical design used was that for a completely randomized experiment, with three repetitions. The evaluated parameters were: germination iniciation and stabilization; final germination percentage; germination velocity index; and total plant height at the end of the experiment. The following results were obtained: iniciation and stabilization occured at 30 and 100 days, respectively, in all substrates; for final germination percentage there was a significant (5%) effect of treatment, with the loam average superior to the others; for germination velocity index there was no significant effect of treatment; and for total plant height there was a significant (1%) effect of treatment, with the loam average superior to the others. From these results one may conclude that germination iniciation and stabilization occurs at 30 and 100 days, respectively, independent of substrate and that loam favors the germination and development process in araçá-pera.
