| description | The present study aimed to determine the imbibition curve and evaluate the effects of ‘reducing the water content of cagaita seeds (Eugenia dysenterica DC.), using the radiographic image analysis technique. To this end, three assays were carried out: seed imbibition curve and root protrusion were determined in assay 1. Seeds in silica gel were oven dried for to 72 h and were then analyzed for water content and vigor in assay 2. Seeds were dried up to certain levels of the water content and were evaluated by radiographic imaging analysis in assay 3. A rapid mass gain was observed in the first 60 imbibition hours and the root protrusion reached 94.4% after 192 imbibition hours. Cagaita seeds did not tolerate drying periods longer than 24 h, which corroborates the recalcitrant behavior of the seeds of these species. The analysis of the radiographic image obtained by an X-ray test allowed the establishment of a direct relation between the increased free space area within the seed and the decrease in the seedling emergence. The drying process altered the internal morphology of the seed and such changes directly influenced the development of the seedlings. |
