Results of statistical models testing the effects of seed identity (P. leptocoma E+ control, P. leptocoma E+ natural, P. leptocoma E− or P. reflexa E−), microsite type (P. leptocoma or P. reflexa) and their interaction on (a) whether or not a seed germinated, (b) the number of weeks to germination for seeds that germinated, (c) whether or not a germinated seedling survived, (d) number of weeks surviving for seedlings that died and (e) combined growth responses (number of live leaves at the time of harvest, aboveground biomass and belowground biomass) using MANOVA.
