| Abstract | Using image analysis techniques for evaluation of internal morphology and vigor of sorghum seeds Image analysis techniques using X-rayed seeds and computerized analysis of seedlings are considered efficient to evaluate the seed quality of various species, with a fast response and methodologies that are easy to implement and reproduce. Thus, this research aimed to evaluated methodologies that associate the internal morphology of sorghum seeds with their physiological potential via radiographed images of seeds and image processing of seedlings. Ten seed lots of the sorghum hybrid 50A70 were used in the study. The study was conducted in two phases; the first involved the utilization of radiographed images of seeds to associate their internal morphology with germination. The second consisted evaluation of vigor using first count germination, accelerated aging, cold test, emergence and speed of emergence in sand, seedling emergence in field and computerized seedling image analysis ("Seed Vigor Image System SVIS ® "), the seedlings were evaluated two and three days after sowing for the germination test, in order to detect variations in the seed vigor among the lots, during four months of storage. The results allowed to conclude that the X-ray test is effective in identifying damage tissue deterioration, mechanical damage, malformation damage and insect damage, enabling to establish a relationship between the observed damage and the negative effect on germination. Computerized analysis of three-day-old seedlings consists in a feasible method to detect differences in the seed vigor among the lots. |
