- Abstract
The aim of this research was verify the efficiency of the controlled deterioration and accelerated aging tests to differentiation of physiological quality of cabbage seeds, cultivars "quatro estações" and "sessenta dias". Seeds were tested for controlled deterioration test (water content of seeds with 16, 18, 20 and 22% at 45 ° C for 24 h) and accelerated aging (45 ° C for 48 h). The seeds were sown in Petri dishes lined with paper germitest and kept in a germination chamber type Biochemical Oxygen Demand (BOD) under constant temperature of 30 °C., were studied germination and vigor. The accelerated aging and controlled deterioration are efficient to identify different levels of seed vigor of cultivars of cabbage "quatro estações" and "sessenta dias", mainly through germination speed index.
