| Abstract | ||
| Seed is the most important factor of propagation and conservation of plant genetic resources in different regions under difficult and prolonged conditions. Seeds are the most important factor for reproduction and conservation of plant germplasm and plant emissions in different regions, survival in harsh conditions and long period generation plants. Seed dormancy breaking is necessary for many rangeland and medicinal species. In the present study, the methods for breaking dormancy of rangeland and medicinal plant seed were studied in laboratory condition. Due to the extent of laboratory operations and number of species, the results included the most suitable treatments and substrate for seed dormancy breaking and increasing of seed germination, summarized and presented in a table. It was generally found that the use of filter paper was the best method to study the viability and seed dormancy breaking of most range and medicinal plants of Iran; however, for the large seeds, the use of sterile sand and a chilling treatment (4 ° C) for 1-2 months was useful. Hard coat seeds need to be treated with chilling, scarification, and chemical treatments. | ||
