【 摘 要 】

The present study aimed to evaluate the physiological quality of seeds of crambe in different storage conditions for nine months. The crambe with moisture content of 4.63% (wet basis) was placed in the packages laminated, PET and HDPE, which were stored in environments: refrigerated at 10 ± 1.19 °C and 34.84 ± 4.09% relative humidity (RH) and natural at 24.81 ± 1.82 °C and 54.93 ± 12.77% RH. The completely randomized design in triple factorial (3 x 2 x 4) with three replications was used. Data were analysed by analysis of variance and regression. The natural environment and packaging PET containers is best to maintain seed quality of crambe for up to six months of storage. The natural environment preserves the seed vigor and promotes overcome primary dormancy as early as the third month of storage. The refrigerated environment at 10 °C is not recommended for storage of seeds of crambe.
