Accelerated aging test to evaluate the quality of crambe (Crambe abyssinica Hochst - Brassicaceae) seed physiology

The present study aimed to evaluate the efficiency of the accelerated aging test to determination of the physiological potential of the Crambe abyssinica Hochst seeds, from two harvests (2009 and 2010). Were evaluated: water content, germination and vigor by germination speed index, accelerated agin...
