“…Since at a given water potential, the lipidrich sunflower seeds contain less water than starchy Phaseolus, the levels determined in Phaseolus may correspond to 0.05 to 0.09 g water* (g dry wt)-' for sunflower seeds (21). Therefore, it is likely that the seeds used in this study (0.045 g water.…”

“…Mean germination time (MGT) was calculated according to the modified equation of Roberts and Ellis (1989): MGT = ΣD n /Σn where n is the number of seeds germinated on day D, and D is the number of days counted from the beginning of germination.…”

“…Coincidentemente, o modelo simplificado (Vp -Vi)/ p = -(tgβ) mostra que a taxa de deterioração da semente (tgβ) equivale a 1/σ da equação de Ellis & Roberts (1980). Nem o genótipo e nem a qualidade inicial da semente afetam a declividade (1/σ e tgβ) das curvas, mas somente a intercepção, K i , da equação de viabilidade (2) é afetada por tais fatores (Roberts, 1973;Roberts & Ellis, 1989). Portanto, a equação simplificada proposta pode ser descrita pelo modelo: Vp = Vi -(tgβ).p, em que Vp é a viabilidade da semente em 'probit' no período p, Vi = Vp quando p = 0, e Vi é a qualidade inicial da semente.…”
