Efeito da colheita mecânica na qualidade fisiológica de sementes de sorgo (Sorghum bicolor L.).

Abstract

Mechanical injury to seeds caused by mechanical harvesting is a serius and inevitable problem. This research evaluated the physiological quality of surghum seeds, by stablishing a Quality Factor (FQ) accounting for germination (%), aging (%), electrical conductivity and cold test (%). It was found that mechanical harvesting causes injury to seeds that reduces its physiological quality.
