Seed weight of Xylopia aromatica (Annonaceae): quality evaluation from X-ray and seedling emergence

Xylopia aromatica (Lam.) Mart. (Annonaceae) is a native species of the Brazilian Savannah (“Cerrado”) region, recommended for the recovery of degraded areas and also for medicinal use. Seeds of some species of the Annonaceae require a long period to germinate and many studies have focused on determining methods which can rapidly analyze seed quality. The objective of this study was to evaluate the quality of Xylopia aromatica (Lam.) Mart. seeds in accordance to their weight, through X-ray images and emergence test. Seeds were collected from dehiscent follicles with a blower and one portion...
