Title
Evaluation of different priming and exposure times on seed germination indices of Green Cumin (Cuminum cyminum)
Authors
Abstract
Green Cumin (Cuminum cyminum) is an annual grass, dark and umbrella in the family of apiaceae. The plant
is an important medicinal plant in Iran and valuable in industry, business and cost-effective to export it
around the world. In order to evaluate the effects of different priming and exposure times on seed
germination indices of C. cyminum a factorial experiment based on completely randomized design with two
factors and three replicates was conducted at Medicinal Plant Research Center, Shahed University in 1392.
The factors were different kind of primings with three levels including polyethylene Glaygvl (PEG6000),
potassium nitrate (KNO3) and potassium chloride (KCL), and exposure times with three levels (12, 24, 36 h).
The results showed that different priming and exposure times had a significant effect on most seed
germination indices. The highest germination percentage and mean daily germination were happened in KCL
(potassium chloride) treatment at 24 h exposure, and the lowest germination percentage and mean daily
germination were happened in KNO3 (potassium nitrate) treatment at 12 h exposure.
