Study of pre-treatments on seed germination of Foeniculum vulgare L., Salvia sharifii Rech. et Esfand. and Abutilon fruticosum Guill. et Perr.

Cultivation programming of medicinal plants is necessary for curing, limiting natural habitats, little reproduction and inexpedient cutting. In this investigation, the effects of pre-treatments on seed germination of Foeniculum vulgare L., Salvia sharifii Rech. et Esfand. and Abutilon fruticosum Guill. et Perr. were conducted. Seeds of species were collected from their main habitates and tested for pre-treatments as sulfuric acid (for 5, 10 and 15 minutes), warm water, cold, KNO3 and control sample. Seeds were sown in Petridishes for 14 days. This experiment was complete randomized design with three replications. According to the results, applying sulfuric acid for 10 minutes as pre-treatment on seeds had higher values of seed germination percent and germination rate on Foeniculum vulgare, KNO3 on Salvia sharifii and sulphuric acid for 15 minutes on Abutilon fruticosum. The highest and lowest vigor index was in Salvia sharifii, 191.75 (control) and zero (sulfuric acid for 10 and 15 minutes), in Foeniculum vulgare 365.75 (cold) and zero (warm water) and in Abutilon fruticosum, 23.4 (sulphuric acid for 10 and 15 minutes) and zero (warm water, cold, KNO3 and control sample).
