Vigor tests of Crambe abyssinica seeds/Testes de vigor em sementes de Crambe abyssinica

The objective was to verify vigor tests efficiency in the evaluation the crambe seeds physiological quality Four lots of crambe seeds of cultivar 'FMS Brilhante' were submitted to the following standard germination and vigour test (first germination count, length and dry mass of seedling, seedling emergence in sand and field, electrical conductivity, accelerated ageing and controlled deterioration). The experiment was conducted in a randomized complete block design for test, evaluating the lots effect. The seedling emergence in field test and the controlled deterioration test at pre-moistened seeds at 15% and maintained under 42[degrees]C/48h and at 25% under 45[degrees]C/ 36h are efficients classifying the crambe seeds lots in different vigour levels. Key words: accelerated ageing, controlled deterioration, crambe. O objetivo deste trabalho foi verificar a eficiencia de testes de vigor na avaliacao da qualidade fisiologica de sementes de crambe. Para isso, quatro lotes de sementes de crambe da cultivar 'FMS Brilhante' foram submetidos aos testes de germinacao e vigor (primeira contagem de germinacao, comprimento e massa seca de plantula, emergencia de plantulas em areia e campo, condutividade eletrica, envelhecimento acelerado e deterioracao controlada), em delineamento inteiramente casualizado com quatro repeticoes. Os testes de emergencia de plantulas em campo e de deterioracao controlada com sementes pre umedecidas a 15% e mantidas a 42[degrees]C/48 horas e a 25% a 45[degrees]C/36 horas sao eficientes na classificacao dos lotes de sementes de crambe em distintos niveis de vigor Palavras-chave: envelhecimento acelerado, deterioracao controlada, crambe.
