Abstract

The initial dormancy in mature seeds of 12 out of 14 species of grass weeds studied was significantly overcome by pretreatment of the dry seeds at 50 C in stoppered vials. The time required for maximum effect varied depending upon species and lots within species. The procedure, termed accelerated after-ripening, can produce seeds in various stages of dormancy simply by varying the duration of the pretreatment. One of the first stages that becomes apparent is an increased response to light.
