Resumo: | 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 was separated into weight categories: very light seeds, light seeds and heavy seeds. Another seed portion was separated in water by their density, into those that sank and those that floated. The seeds from each weight category were weighed and X-rayed. A further seed portion from the categories (separated by blower and in water) was also placed in 500 mg L-1 of a solution [gibberellin 4 (GA4) + gibberellin 7 (GA7) and cytocinin] to overcome dormancy and was later sown in soil taken from the “Cerrado”. The internal seed morphology andseedling emergence of X. aromatica were influenced by seed weight. The elimination of badly formed and insect- infested seeds improved the physiological potential of the seed lot. The X-ray test can efficiently evaluate seed quality but does not permit a visualization of the embryos. |
