TOLERÂNCIA À DESSECAÇÃO EM SEMENTES DE SUCUPIRA (Bowdichia virgilioides Kunth.) - Fabaceae
The purpose with this experiment was to evaluate the sucupira-preta seeds tolerance to the desiccation. Seeds initially with 10.63% of humidity were submitted to a drying until reaching the following water tenors: 10.63% (control); 10.0%; 9.5%; 9.0%; 8.5%; 7.5%; 7.0%; and 6.5%. Then they were prehea...
