Effect of Different Physicochemical Treatments on Seed Dormancy of Medicinal Herbs (Portulaca oleracea L.)

Habib Yazdanshenas, Maliheh Nasiri and Ali Tavili

Abstract:
The objective of the present study was an assessment of different treatments on seed dormancy, germination percentage, velocity of germination and seed vigor index on Portulaca oleracea L. herb. This experiment was arranged out as completely randomized, based on CRD design with 4 replications. For this purpose seedling characteristics were measured: six different physical and chemical treatments including freezing, wetting and drying, pre-chilling, nitrate potassium and sulfuric acid compared with control sample. The results showed a significant effect of nitrate potassium, wetting and drying, pre-chilling and boiling treatments on seed dormancy (p<0.01) and had 52, 49, 40 and 34% germination, respectively. However Freezing (29%) and sulfuric acid (31%) didn’t show any significant effect on germination of this plant seeds.
