Effects of different storage methods on germination and seedling growth of Corispermum patelliforme seeds

Dormancy appeared during germination of Corispermum patelliforme seeds. The aim of the study was to explore seed viability and the optimal temperature for seed germination and seedling length. The dormancy was broken during the course of seed storages and the optimal seed storage method was selected for dormancy-breaking. The results showed that seed viability did not change after stored at different conditions. If stored at RDS (Room dry storage) and RSS (Room sand storage) conditions, the optimal temperature for seed germination was 20 ℃ and 25 ℃, 25 ℃, respectively. Germination rate increased after storage with the following order: CDS (Cold dry storage)FSARDSRSSFSS (Field sand storage). The optimal temperatures for seed germination and seedling growth ranged within their optimal seed storage temperatures for RDS and RSS which suggested that CDS was the best storage method among these five studied seed storage methods for C. patelliforme.
