Aspidosperma pyrifolium Mart. & Zucc. (Apocynaceae) is a tree present in the Brazilian semiarid Region and it may be used as timber or as raw material for cosmetic and medicinal purposes. Sustainable methods of management are important to improve and to assure sustainable forest yield. Among these methods, we can note the physical treatment to improve vigor in forest seeds with the use of ultrasound (US) and microwave (MW). The aim of this research aimed was to test the use of US and MW to improve vigor to A. pyrifolium seeds. The seeds were submitted to the following treatments: 1) MW: 0, 5, 10, 15, and 20 s and 2) US: 0, 1, 2, 3, and 4 min. After treatment, the seeds were sown on paper rolls and incubated in BOD (25 ± 2 ºC, seven days, 12 h photoperiod). The seeds were evaluated for vigor’s characters during 14 days. The results were analyzed by linear regression and Pearson correlation, using R program. The physical treatments US and MW did not show positive effects to enrich vigor in A. pyrifolium seeds.
