Produção e qualidade de sementes de Crambe abyssinica no Sul Fluminense

Abstract

The objective of this dissertation, was evaluate of production and quality crambe seeds cv. FMS Brilhante below sunflower plants residues, both adjust methodologies to evaluate seed vigor of this specie. Were evaluated production components, yield and physiological quality seeds. Also evaluated oil yield, harvest index and nutrients content seeds. Moreover, were adjusted of vigor tests (first germination count, length and dry mass of seedling, seedling emergence in sand and field, electrical conductivity, accelerated ageing and controlled deterioration). The results obtained, was found that, sunflower plants residues favor the production components (seeds weight per plant and thousand seed weight), yield and physiological quality crambe seeds, that were produced. However, adjust methodologies to evaluate seed vigor, showed controlled deterioration test at pre-moistened seeds at 15% and maintained under 42°C/48h and at 25% under 45°C/36h, both seedling emergence in field test, are efficient classifying the crambe seeds lots in different vigour levels.
