BREAKDOWN OF SEED DORMANCY IN Canavalia brasiliensis

, 2007
Canavalia brasiliensis has a great potential as green manure in Brazilian Savanna. The species gives nitrogen to subsequent crops and produces excellent dry matter. On the other side, even under suitable environment conditions, several seeds don’t germinate due to the impermeable seed coat. This trial aimed to identify different treatments for dormancy
