SILVA, Girlânio Holanda Da et al. Germination of stored Belamcanda chinensis (L.) DC seeds. Ornam. Hortic. [online]. 2018, vol.24, n.2, pp.149-154. ISSN 2447-536X.  http://dx.doi.org/10.14295/oh.v24i2.1176.

The leopard lily (Belamcanda chinensis) is an exotic ornamental Iridaceae in Brazil and cultivated as a medicinal plant in its countries of origin (China and Japan). It is propagated by rhizomes and seeds; however, the viability of these seeds after storage remains unknown. The aim of this study was to evaluate the germinability of stored B. chinensis seeds. Seeds harvested between March and April 2010, 2011, 2012 and 2013 were separated by year and stored in paper bags in a room without relative humidity and temperature control. Seeds from these four years were analyzed for moisture content, 100-seed weight and germination index. The freshly harvested seeds (2013) and those stored for one year (2012) exhibited 72% and 41% germination, respectively, and 80% and 47% primary root emission at the end of 20 weeks. However, seeds stored for two and three years (2010 and 2011) did not germinate. B. chinensis seeds remained viable for up to one year of storage.
