Qualidade sanitária e fisiológica de sementes de canola durante a armazenagem

Abstract

The culture of rapeseed (Brassica napus L.) has been considered a great potential economic world, providing opportunities for the production of oils, income stability, and use of the available means of production. But related research will evaluate the quality of seeds of this culture are still scarce. The aim of this study was to evaluate the physiological and sanitary quality of six lots of canola seeds stored for 10 months and kept in the refrigerator will 4º C. After 0, 60, 120, 180, 240 and 300 days of storage seed quality was evaluated by germination, seedling length, health and emergency speed index. The experimental design was completely randomized in a factorial 2x6 (lots x storage periods) with four replications, being individually assessed each cultivar with their respective lots. Data were submitted to analysis of variance and the means compared by Tukey test at 5% (p < 0,05). There was an effect of the storage period with respect to all variables, but also difference in the performance of lots of each cultivar. The IVE after storage was more accurate for the separation of batches at the level of force and with respect to health, there was a high incidence of fungi in the canola seed.
