Determination of important biotechnical characteristics of some safflower (Carthamus tinctorius L.) cultivars
Abstract
The study aimed to determine the biotechnical characteristics (physical properties, color characteristics, angle of repose, and coefficient of friction) of the seeds of safflower cultivars. Moisture contents of Asal, Balcı, and Dinçer cultivars were determined as 8.64%, 9.52%, and 8.57%, respectively. The width (4.04 mm) of the Dinçer cultivar gave higher values than other cultivars. Statistically significant (p<0.01) differences were determined between the width values of safflower cultivars. There was no statistically significant difference in length, sphericity, surface area, and geometric mean diameter values between cultivars, but statistical differences at p<0.05 level were determined between cultivars in thickness values. L* brightness color value was higher (75.31) in Dinçer cultivar than in other cultivars. The rubber surface gave the highest values (0.360-0.384) in terms of coefficient of friction values. In the study, it is thought that the biotechnical characteristics (physical properties, color characteristics, coefficient of friction, and angle of repose values of the safflower seeds will contribute to obtaining important engineering data in the design of machinery, facilities, and systems to be used for sowing, harvesting and threshing mechanization and postharvest technologies.
