Abstract :

The physical properties of safflower seeds like those of other grains are essential for designing of equipment for handling, harvesting, aeration, drying, storing, dehulling and processing. The objective of this study was to investigate the effect of variety on some physical properties of safflower kernels cultivated in Markazi State. Study of physical properties of 4 varieties of safflower kernels (Goldasht, Padideh, PS and Esfahan 28) at base moisture content (5.5% w.b) showed that effect of variety on length, sphericity percent and aspect ratio as statistically at 1% level and on thickness and arithmetical mean diameter of kernel at 5% level is significant. Thickness and geometrical mean diameter of kernels are about 3 mm and 3.6 mm, respectively. Geometrical dimensions of Esfahan 28 variety are more than other varieties. Maximum and minimum percent of sphericity and aspect ratio at PS and Esfahan 28 varieties was shown respectively
