| Abstract | ||
| In order to investigate the effect of seed size onemergence percentage, seedling establishment and some quantitative characteristics of four Safflower genotypes, (Goldasht, Padideh, Mahalli Esfahan and Sina) and three sizes of seed (small: 2-3mm, large: andgt;3mm and control: no sorting) an experiment was conducted in the field of Seed and Plant Certification and Registration Institute, during 2008-2009, located in Karaj. The seeds were planted in (4andtimes;3) factorial arrangement based onrandomized complete block design with three replications. The results expressed significant differences among cultivars for all traits except number of plant per plot, also significant differences observed among all sizes for whichcultivars Goldasht and Padideh for most of the traits were superior than other cultivars. According to mean comparison, large seeds with the highest amount of SEP (80.75%), 1000-SW (51.96g), Seed Yield (230.75g/m2 ) were superior compare to control and small seeds. Since Goldasht and Padideh were superior than other cultivars, also creating vigorous seedlings by large seeds, using cultivars with adequate food storage and selecting large seeds with more germination potential to obtain higher yield and good plant establishment recommended | ||
