Effect of Priming and its Duration on Quality of In-pod Seeds Germination and Seedling Vigour of Sainfoin 'Eski' under Laboratory Conditions %K germination and seedling growth %K Sainfoin %K Seed priming %K time %R 10.22059/jci.2013.36095 %X To study the effects of priming on seed germination traits of sainfoin 'Eski', a factorial in randomized complete block design with three replications was conducted at the laboratory of agricultural research center of Sari in 2011. Treatments consisted of polyethylene glycol (PEG6000) at 5 and 10%, potassium nitrate (KNO3) at 5 and 10% and potassium chloride (KCl) at 5 and 10% levels and 6, 12 and 24 hours of treatment duration. The most significant interaction of time × priming vigor, root length and germination rate was achieved by priming solution containing PEG 10% for 12 hours. The highest germination percentage and total number of seedlings was achieved by 5 and 10% PEG for 6 and 12 hours and the least with a solution of KCl 10% for 6 hours, respectively. The highest shoot length and seedling length was obtained at PEG 10% for 12 hours and the least at KCl 10% for 24 hours. The highest and lowest number of normal seedlings, were observed by a solution of PEG 10% for 12 hours and KCl 10% for 24 hours, respectively. The highest R/S ratio was obtained in a solution of PEG 5% for 6 hours and the lowest ratio was observed in the solution of KNO3 10%. The lowest weight ratio of R/S was obtained in a solution of KNO3 and KCl 10% for 6 and 24 hours and the highest dry weight of R/S in priming with PEG 10% for 12 hours. %U https://jci.ut.ac.ir/article_36095_b44d1111eb7ac04ecdb87a1dad83dd2d.pdf
