| Abstract | ||
| According to importance of Salsola rigida in arid and semi arid regions, also due to Artemisia sieberi allelopathic property, this research was carried out to find whether or not Sa. rigida is sensitive against Ar. sieberi allelochemicals in germination stage when they are planting with together. For this purpose, Sa. rigida seeds were taken from Pakan Bazr Cooperation in Isfahan. Aerial parts of Ar. sieberi were gathered from Jafarieh region in Qom province, dried and powdered. They were mixed with distilled water in a ratio of 1:3 (one part Sa. rigida powder, 3 parts distilled water). Based on standard methods, extracts with different concentrations were prepared. Sa. rigida seeds were put in Petri dishes and watered with different concentrations of the prepared extracts. Experiment was done in a completely randomized design with 4 treatments (0, 25, 50 and 100 percent extractions) and 4 replications. Understudy germination properties were Final Germination percentage (FG), Rate of Germination (RG), Mean period of Final Germination (MPFG) and Percentage of Inhibition (PI). Duration of experiment was 13 days. Results based on statistical analysis revealed that there was significant difference between FG, MPFG, and PI under different extract concentrations effects (P<1%) while for RG difference was significant at 5% probability. Totally, it is concluded that Sa. rigida could be affected by Ar. sieberi allelopathic property in germination stage. | ||
