Murici (Byrsonima verbascifolia Rich) is a fruit bearing plant of great medicinal importance in the savannah; however, its propagation is hindered by the fact that the seeds have low germination and seedling emergence in the field is slow.
This study evaluated the effect of different dormancy breakage methods in murici seeds.
Therefore, were evaluated effect of different temperatures; soaking in gibberellic acid and water; chemical and mechanical scarification and two types of substrate (distilled water and KNO3).
Treatments were arranged in a randomized block design.
Records made daily on the number of germin...
