Abstract

Seed germination is an important event in the life of every sexually reproduced higher plant. The seed of many medicinal plant species have dormancy, which they do not germinate unless specific environmental signals or events occur. This study was carried out to evaluation the effect of different treatments on seed dormancy and germination of Chahar Mahal & Bakhtiyari local thyme (Thymus daenensis) was done in completely randomized design (CRD) with three replications. These treatments were: gibberellic acid 100 PPM, gibberellic acid 500 PPM, gibberellic acid 1000 PPM, KN₃  0.2%, thiourea 1 Molar  and control. The results of analysis of variance (ANOVA) showed that the effect of various treatments on thyme seed germination percentage were significantly different (P<0.01). Treatments of KNO₃ (0.2%) and Thiorae (1 Molar) have the highest and lowest seed germination percentage.
