Germination and establishment of bioenergy grasses outside cultivation: A multi-region seed addition experiment. 2012 to 2014 [Ontario, Canada and Illinois and Virginia, United States of America]

This study evaluated the effects of propagule pressure (number of seed additions) and establishment limitations for early establishment of four potential bioenergy grasses in agricultural field margins and forest understory across a 6.3° latitudinal gradient (Ontario, Canada and Illinois and Virginia, United States of America). The experimental design involved the use multiple seed introductions in different years and followed the success of their establishment and persistence for up to three growing seasons.
