On the mobilization of reserve starch under the action of glucanphosphorylase in Panicum miliaceum and Bromus sterilis
Abstract
The main objective of the study was the quantitative determination of the reserve starch and of the total soluble
proteins, in correlation with the dynamics of the α-glucanphosphorylase activity from the caryopses, subjected to
germination under laboratory conditions, belonging to two graminaceae species from the cultivated (Panicum miliaceum)
and spontaneous (Bromus sterilis) flora. The experimental results obtained put into evidence a differentiated dynamics for
both the enzymatic activity and protein and starch concentration, as a function of species - on one side - and germination
time - on the other.
