VIGOR OF CANOLA SEEDS THROUGH QUANTIFICATION OF CO 2 EMISSION Vigor de sementes de canola quantificado pela liberação de CO 2

摘要: Seed marks the beginning of grain production from cultivated crops. Ensuring seed quality is priority in field technology. In this context, purpose study was to evaluate use carbon dioxide concentration classify Brassica napus lots different resulting various sowing dates. were evaluated by percentage normal plantlets and germination rate index. CO 2 quantified samples submitted five periods incubation at 40° C with aid a gas exchange analyzer coupled an injection airflow system. The results subjected analysis variance mean values compared Duncan test regression 5% level significance. B. seeds all showed high Percentage correlated concentration. Determination more efficient three hours which allowed classification canola into four vigor classes. inversely proportional plantlets.
