ﺑﺮرﺳﻲ ﺗﺎﺛﻴﺮ روشﻫﺎی اﺳﻤﻮ ﭘﺮاﻳﻤﻴﻨﮓ ﺑﺮ ﺧﺼﻮﺻﻴﺎت ﺟﻮاﻧﻪزﻧﻲ ﺑﺬر زﻳﺮه ﺳﺒﺰ (Cuminum Cyminum)

ming is one of the ways for seed germination, which usually are used under the absence of the necessary environmental factor. In order to evaluate the effects of different priming on seed germination indices of C. cyminum a factorial experiment based on completely randomized design with three factors and three replicates was conducted at Medicinal Plant Research Center, Shahed University in 1392. The factors were polyethylene Glaygvl (PEG6000) with two concentrations (5% and 10%), potassium nitrate (KNO3) with two concentrations (1% and 2%) and potassium chloride (KCL) with two concentrations (2% and 4%). The results showed that the priming significantly affected most seed germination indices. The maximum and minimum germination percentage was happened in 4 % of KCL and 1 % of KNO3, respectively. The minimum germination rate daily under KCL and PEG treatments were happened in four and 10 percent concentrations, respectively. In addition, the maximum seed germination rate under KNO3 was happened in one percent.
