Assessment of Some Physical Properties and Germination Characteristics of Ereğli and Kırıkhan Local Population Black Carrot Seeds

Nowadays, food production and food security are an extremely important issue. Seed is of great importance for maintaining and securing crop production capacity. It is also necessary to protect gene resources and to apply new technologies. This study examined physical properties and germination parameters of calibrated black carrot seeds from the local populations S1 (Ereğli) and S2 (Kırıkhan). The length, width, thickness, geometric mean diameter, sphericity, projected area, volume, thousand grain weight, bulk density, bulk density, and terminal velocity values of the seeds of S1 population at 3.96% moisture level were determined as 3.95 mm, 1.65 mm, 0.98 mm, 1.84 mm, 0.47, 5.18 mm², 2.01 mm³, 2.51 g, 0.431 gcm-³, and 1.80 ms-1, respectively. Moreover, those values for S2 population seeds were found to be 3.61 mm, 1.46 mm, 0.82 mm, 1.62 mm, 0.45, 4.55 mm², 1.37 mm³, 2.21 g, 0.395 gcm-³, and 1.75 ms-1 at 4.45% moisture level, respectively. Germination percentages, MGT, GI, GRI and CVG values of S1 and S2 variety seeds were 85% and 81%, 4.52 and 3.50 days, 548.5 and 574, 20.85 and 28.52 % day-1, 22.20 and 28.79, respectively. The data obtained from this study will guide future studies on black carrot cultivation and seed processing technology.
