Description
Summary:The objective of this study was to evaluate the physiological and sanitary quality of seeds of rocket; the research was done at the Laboratory of Seed Analysis and greenhouse of the Department of Plant Science, Federal University of Pelotas (UFPel). Four lots of the cultivar "Antonella'' were tested for following features: initial and final moisture content, germination rate, first count of germination, accelerated aging with saline solution, dry matter contents, seedling shoot and root length, emergence speed index, emergence of seedlings in substrate, electrical conductivity and sanitary condition. A completely randomized design with four replications was used for all tests done and means were compared by Tukey test (P≤0.05). For all tests performed it was concluded that despite changes in the ranking of the best lots, there was agreement regarding the indication of the inferiority of the lot 3 in all tests and it was also observed that the incidence of fungi associated with seeds of rocket interfere with the physiological quality of the lots. O objetivo nesta pesquisa foi avaliar a qualidade fisiológica e sanitária de sementes de rúcula. O trabalho foi conduzido no laboratório e em casa de vegetação do Departamento de Fitotecniada Universidade Federal de Pelotas (UFPel). No ensaio, foram utilizados quatro lotes de sementes de rúcula da cultivar 'Antonella', sendo efetuados os seguintes testes: grau de umidade inicial e após o envelhecimento acelerado, germinação, primeira contagem de germinação, envelhecimento acelerado com solução salina, massa seca da parte aérea e de raiz de plântulas, comprimento da parte aérea e de raízes de plântulas, índice de velocidade de emergência, emergência de plântulas, condutividade elétrica e teste de sanidade, em delineamento experimental inteiramente casualizado, com quatro repetições, sendo que as médias foram comparadas pelo teste de Tukey (P≤0,05). Apesar das alterações na classificação dos melhores lotes, nos testes analisados, verificou-se concordância quanto à indicação da inferioridade do lote 3 em todas as avaliações. Verificou-se que a incidência dos fungos associados às sementes de rúcula interfere na qualidade fisiológica dos lotes.
