“…Microwaves were used for drying Curcubita melo (Diniz et al, 2020), Oryza sativa (Rifna et al, 2019), Avena sativa (Miano et al, 2019;Rifna et al, 2019) and Parkia multijuga (Miano et al, 2019), for example. All these authors described that the seeds when submitted to this process lose water by capillarity, from the inside to the outside of the tissues.…”

Aspidosperma pyrifolium Mart. & Zucc. (Apocynaceae) é uma árvore presente no semiárido brasileiro, utilizada para exploração madeireira, cosmética e medicinal. Métodos sustentáveis de manejo são importantes para melhorar o rendimento e garantir a produção florestal sustentável. Dentre esses métodos, podemos citar o tratamento físico para melhorar o vigor das sementes, com o uso de ultrassom (US) e micro-ondas (MW). Esta pesquisa teve como objetivo testar o uso de US e MW para melhorar o vigor de sementes de A. pyrifolium. Sementes desta espécie foram submetidas aos seguintes tratamentos: 1) MW: 0, 5, 10, 15 e 20 s e 2) US: 0, 1, 2, 3 e 4 min, sendo em seguida semeadas em rolos de papel e incubadas em câmara de germinação (BOD) (25 ± 2 ºC, sete dias, fotoperíodo de 12 h). As sementes foram avaliadas por 14 dias sobre variáveis de germinação e vigor e os resultados foram analisados por regressão linear e correlação de Pearson, com o programa R. Os tratamentos físicos US e MW não apresentaram efeitos positivos para enriquecimento do vigor de sementes de A. pyrifolium.

“…This research was conducted in the municipality of Sumé, located in the western Cariri micro-region of Paraíba, northeastern Brazil. The climate in the region is characterized by rainfalls concentrated in 3 or 4 months, irregularly distributed in time and space, with mean annual temperatures relatively high (25-27ºC), mean insolation of 2,800 hours/year, relative humidity about 50%, and mean evaporation rates around 2,000 mm/year [19].…”

This study aimed to determine the biometric characteristics of seeds of Tabebuia aurea and evaluate the effect of different periods of water immersion on the initial growth of seedlings. For this, the following dimensions were analyzed: length, width, and thickness of seeds with lateral wings and embryo. The moisture content, weight of a thousand seeds, and the number of seeds per kilogram were determined. The seeds were subjected to 11 treatments, as follow: control (no immersion in water; 0 hours) and periods of water immersion for 6,12,18,24,30, 36, 42, 48, 54, and 60 hours, with four replications of 25 seeds in each treatment. The aerial part and seedling root lengths were analyzed 30 days after sowing. The water content was 9.81% and the weight of a thousand seeds was 130.260 g, corresponding to about 7,677 seeds/kg. The seeds with lateral wings had mean length, width, and thickness of 5.252, 1.226, and 0.147 cm, respectively. For the embryo, these dimensions corresponded to 1.355, 0.805, and 0.103 cm. Regarding the aerial part and root length of T. aurea seedlings, immersion for 48 hours is recommended because this treatment had the best results.
