Aim and Background:
Ducrosia anethifolia Boiss is from the Apiaceae family, which is used in traditional medicine as a headache and back pain remedy. This research was conducted to select the best pretreatment for breaking seed and seed germination and seedling growth.
Material and methods:
Experiment was conducted in a completely randomized design with 6 treatments and 4 replications in University of  Kashan in 2016. Treatments included potassium nitrate 0.1% and 0.2% for 72 hours, sulfuric acid 98% for 5 minutes, chilling for 35 days at + 5 ° C, soaking in distilled water and control.
The results showed that the effect of different treatments on germination percentage, germination rate, root and stem length and fresh and dry weight were significant at 1% probability level. Sulfuric acid scarification treatment completely prevented germination.
The highest germination percentage was observed in potassium nitrate solution. Therefore, potassium nitrate is useful in response to metabolic processes of the seeds
Considering that the most important reason for reducing the distribution of this plant is the length of the seed dormancy, the use of the results of this study will help to germination of this herb.
