- ... Starch is the principal reserve of Araucaria araucana seeds, and it is hydrolysed during germination mainly by alpha-amylase. There are several alpha-amylase isoenzymes whose patterns change in the embryo and in the megagametophyte from the one observed in quiescent seeds (T0) to a different one observed 90 h after imbibition (T90). The objective of this research was to study the roles of two puri ...
