Sunflower seed vigor evaluation by seedling image analyzeThis 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.
