Resumo: Crambe, native from Mediterranean zone, belonging to the Brassicaceae family, is a rustic crop that e merges as a productive alternative, with a potential for the production of feedstock for biodiesel, with emphasis on its oil quality. This study aimed to evaluate the effects of temperature and substrate on seed germination crambe, FMS Brilhante cultivar. The experimental design was completely randomized in a factorial 2 x 7 (temperature x substrate) with 4 replicates of 25 seeds. The seeds were placed on substrates Germitest® paper and clay soil + sand and subjected to temperatures of 9°C, 12°C, 15°C, 20°C, 25°C, 30°C and 35°C. Seed germination percentage and germination speed index were evaluated. The temperature of 25°C is ideal for testing the seed germination of crambe. Temperatures below of 12°C and above of 30°C are detrimental to the germination process. The substrates germitest® paper and sand + clay soil are suitable for testing germination, since observed temperature of execution. The use of paper substrate at temperatures lower than 20°C underestimate the seed germination.

O trabalho teve por objetivo avaliar os efeitos de diferentes temperaturas e substratos na germinação de sementes de crambe, cultivar FMS Brilhante. O delineamento experimental foi o inteiramente casualizado no esquema fatorial 7 x 2 (temperaturas x substratos) com 4 repetições de 25 sementes. As sementes foram colocadas em substratos papel Germitest® e solo argiloso + areia e submetidas ao teste de germinação sob temperaturas de 9°C, 12°C, 15°C, 20°C, 25°C, 30°C e 35°C. Foram avaliados a porcentagem e o índice de velocidade de germinação. A temperatura de 25°C é a ideal para a realização do teste de germinação de sementes de crambe. Temperaturas inferiores aos 12ºC e superiores aos 30°C são prejudiciais ao processo germinativo. Os substratos de papel Germitest® e solo argiloso + areia são adequados para realização do teste de germinação, desde que observado a temperatura de execução. O uso de substrato papel sob temperaturas menores a 20° C subestimam o potencial germinativo das sementes. UEL2012-10-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Laboratórioapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/796210.5433/1679-0359.2012v33n5p1825Semina: Ciências Agrárias; Vol. 33 No. 5 (2012); 1825-1830Semina: Ciências Agrárias; v. 33 n. 5 (2012); 1825-18301679-03591676-546Xreponame:Semina.
