          Abstract

          O trabalho teve como objetivo avaliar a eficiência do sistema computadorizado de análise de imagens de plântulas Seed Vigor Imaging System (SVIS(r)), em comparação com os outros testes recomendados para determinação do vigor de sementes de girassol. Foram utilizados dez lotes de sementes, cultivar Catissol 01, os quais foram avaliados quanto ao potencial fisiológico por meio dos testes de germinação, envelhecimento acelerado, emergência de plântulas em areia e em campo e análise de imagens de plântulas com o sistema SVIS(r), aos 0 e 4 meses de armazenamento. O delineamento experimental utilizado foi inteiramente casualizado para os testes realizados em laboratório e blocos ao acaso para o teste de emergência de plântulas em campo; em ambos os casos, foram utilizadas 4 repetições. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Scott Knott a 5% de probabilidade. Verificou-se que a análise computadorizada de imagens de plântulas com SVIS(r) é eficiente para avaliação do vigor de sementes de girassol.

          Translated abstract

          This study aimed to evaluate the efficiency of computerized image analysis of seedling Seed Vigor Imaging System (SVIS(r)) compared with the other recommended tests to determine vigor in sunflower seeds. It was used ten seed lots of cultivar Catissol 01.The physiological potential was assessed using tests of germination, accelerated aging, seedling emergence and seedling image analyze with SVIS(r) at 0 and 4 months after storage. The experimental design was completely randomized for the laboratory tests and randomized blocs to seedling emergence on the field; in both cases it was used four replications. The data were submitted to variance analyze and mean comparisons at Scott Knott test (P<0,01). Seedling image analyze with SVIS(r) is efficient to access sunflower vigor seeds.
