This research laboratory done in 2010 at the Faculty of Agriculture, Chamran University was for effects of seed priming on germination and initial growth of Dianthus barbatus seeds compared with controls (not Prime). Seed priming is a method that allows water uptake as controlled before planting the seeds will germinate the primary activities such as activation of hormones, enzymes and dissolve the food materials stored. However, the rooting is prevented from leaving and then the seeds are dry until planting is able to maintain capability. Priming is benefits for action many including, increased viability, germination rate under low temperature, increased root yield, increase the power of germination and seedling establishment under conditions fungal infections, increase the power of germination under salinity and drought, reducing the need for Water green and finally to establish better and more plants per unit area in different plants. In this experiment, Sweet William seeds were placed for 24 h in solutions GA3 (with two concentrations 50 and 100 ppm), KNO3 (0.5 and 1%), KH2PO4 (1 and 2.5%). After completion of priming, seeds were dry at room temperature and dark conditions. For evaluation behavior of germination, 20 seeds from each treatment was placed within the Petri dish between two layers of filter paper, in 5 ml distilled water to each petri dish was added, for germination was transferred germinator 2±25 °C. Design was used in this study based on factorial Completely Randomized Design. At the end of germination were evaluated traits such as root length, shoot length, germination percentage, and dry weight plant. Test results showed that seed treatment with gibberellin solution concentration of 100 ppm was significant germination, root length, and shoot length in comparison with other treatments as a significant level of 5%.
