Figure 2. Seed germination after accelerated aging. The germination of Brassica oleracea seed from cultivars Lintop and Maverick was assayed after seeds were stored for 2 to 7 d, under conditions designed to accelerate deterioration in viability (46°C and 75% relative humidity). Unbroken line: untreated seeds; dotted line: partially hydrated (primed) seeds; broken line: primed seeds in which shelf life was induced using a slow drying and heating treatment.
