The use of efficient procedures for seed analysis is essential for quality control programs, helping to select the materials with the greatest potential for seedling production, as well as for monitoring during seed storage. The objective of this research was to identify appropriate procedures of accelerated aging test to evaluate Parapiptadenia rigida (Benth.) Brenan seed vigor. Parapiptadenia rigida seeds represented by 3 lots. Seed moisture content was measured and germination capacity were evaluated; seed vigor was evaluated by electrical conductivity, seedling length, fresh and dry seedling weight obtained after seedling length test and with different accelerated aging tests. Results showed that Parapiptadenia rigida seed vigor can be evaluated efficiently by accelerated aging tests, using combinations of 38 ° C for 24, 48 or 72 hours and 41 ° C for 24 hours.
