Abstract
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) didnot germinate. B. chinensis seeds remained viable for up to one year of storage.
Highlights
The ability of seeds to germinate can change during storage, since they start to deteriorate after harvest and lose their viability
Owing to the difficult germination and lack of knowledge on the storage capacity of B. chinensis seeds (SILVA et al, 2017), studies investigating the storage capacity of these seeds are needed to ensure their availability in seed conservation programs. Given these aspects reported in the literature, the aim of this study was to explore the storage feasibility of B. chinensis seeds
B. chinensis seeds collected from dehiscent fruits in March and April 2010, 2011, 2012 and 2013 were separated by year in single-layer Kraft paper bags, and stored in a room with no temperature or relative humidity control
Summary
The ability of seeds to germinate can change during storage, since they start to deteriorate after harvest and lose their viability. This has ecological and agronomical implications for understanding the mechanisms underlying loss of vigor during seed storage (NGUYEN et al, 2015). Among the factors that most affect the storage environment and seed conservation are temperature and relative humidity (BASS, 1980; DOIJODE, 2001; SCHORN et al, 2010; UMARANI et al, 2015; VENIAL et al, 2017). Information on the best storage conditions for the species Belamcanda chinensis nonexistent
