Chamber temperature and seed moisture content can influence the accelerated aging test results and consequently their interpretation. This work was conducted to determine the effect of initial dry bean seed moisture content on the accelerated aging test results, and the conditions of temperature and relative humidity in the two aging chambers and the gerbox (inner chambers), during the test. Samples obtained from four seed lots of dry beans were adjusted to 8, 10 and 12% initial seed moisture. The seed samples were aged using two chambers (water-jacketed chamber) and a germination chamber (BOD type). During the test, the conditions of the temperature and the relative humidity in the outer and inner chambers (gerbox) were measured using a datalogger. There was little variation in the temperature and relative humidity for both chambers, being however lower for the water-jacketed chamber. Due to the higher relative humidity in the water-jacketed chamber, the seed moisture content was higher when compared to the BOD chamber. Both chambers (water-jacketed and BOD) can be used for the dry bean seed accelerated aging test.Downloads
