The main objective of the present investigation referred to the activity of amylase and α-glucanphoshorylase, two enzymes involved in the metabolism of reserve glucides in two graminaceae species (Sorghum sudanense and Sorghum vulgare), in correlation with the dynamics of starch concentration, followed along ten germination days. The results obtained evidenced that the enzymatic activity follows a Gauss-type curve, with a minimum in the beginning of the germination process and a maximum recorded over the 144 - 192 germination hour interval, unlike the starch concentration, characterized by a decreasing dynamics along the whole time interval under analysis.
