Seed size, physiological quality and brassica transplant development
Seed grading may increase the seed quality and consequently the transplant performance and stand establishment in the field. 'Ramoso de Brasília' broccoli, 'Vitória de Verão' cauliflower and 'União' cabbage seeds were classified using round screens generating tree lots (>2.0, between 2.0-1.5, <1.5 mm); the original seed lot was used as control. The physiological seed quality (germination, first counting and accelerated aging) and transplant development (fresh and dry weight of shoot and root, and leaf area) were determined. The results indicated that seed grading affected the seed weight and especially seed vigor. Large seeds led to better transplant quality.
