Table 4 GLM analysis comparing germination rates between experiments (A) ‘Germination in Water’ and (B) ‘Germination Over a Substrate’. In both cases, GLM design is factorial: treatment (Treat, days of immersion in water) and condition (Cond, seed scarified or unscarified). Significant results are highlighted in bold

From: Rivers as a potential dispersing agent of the invasive tree Acacia dealbata
