Abstract

Seeds of Solanum stramonifolium Jacq. (SM 293) and Solanum torvum Sw. (SM 287 and SM 259) were harvested at 70 days after anthesis and kept in dry storage at 20oC and 30oC for five months to determine the seed dormancy periods. The results showed that seed dormancy of these accessions was broken after three months of storage at 20oC or five months at 30oC. Under both storage regimes, the dormancy of S. stramonifolium was broken faster than S. torvum. When newly harvested seeds of these three accessions were treated with various methods for breaking dormancy, it was found that dormancy could also be overcome by the following treatments: 12 hour soaking, 30 minute pre-washing, one-day pre-heating at 50oC, pre-chilling at 5oC for one day (SM 293 and SM 287) and five days (SM 259), 0.1% KNO3 or 0.01% GA3.
