Testes de vigor em sementes de Crambe abyssinica

Abstract

The objective was to verify vigor tests efficiency in the evaluation the crambe seeds physiological quality. Four lots of crambe seeds of cultivar 'FMS Brilhante' were submitted to the following standard germination and vigour test (first germination count, length and dry mass of seedling, seedling emergence in sand and field, electrical conductivity, accelerated ageing and controlled deterioration). The experiment was conducted in a randomized complete block design for test, evaluating the lots effect. The seedling emergence in field test and the controlled deterioration test at pre-moistened seeds at 15% and maintained under 42°C/48h and at 25% under 45°C/ 36h are efficients classifying the crambe seeds lots in different vigour levels.
