Germination Parameters of Different Types of Black Carrot Seeds of Ereğli Local Population

Abstract

Consumer interest in healthy foodstuffs and vegetables has continuously been increasing. In this sense, quality has become a prominent issue in production, consumption and marketing of vegetables. Seeds and planting processes significantly affect quality of vegetables. Black carrot production is an important source of income for local farmers of Ereğli and Karapınar Districts of Konya province. Bare seeds of Ereğli local population are commonly used in black carrot production. Farmers produce their own seeds. These seeds undergo only one sieving and are not calibrated. In this study, uncalibrated bare, calibrated and coated seeds were planted and germination parameters were investigated. Experiments were conducted in Kuzukuyu village of Ereğli District, at three different planting distances (2.5, 5.0 and 7.5 cm) in randomized blocks design (3x3) with 3 replications. Planting was done in three rows on a ridge (with 7.5 cm row spacing) at a forward speed of 0.64 m s-1. Mean germination time was calculated as 19.90 days for uncalibrated bare seeds, 20.14 days for calibrated bare seeds and 20.79 days for coated seeds; germination rate index values were respectively calculated as 0.431, 0.761 and 0.656 [seeds (m days)-1]; field emergence rates were respectively calculated as 37.13%, 60.97% and 55.19%; number of plants per unit area were respectively determined as 42.35, 69.14 and 59.61 plants m-2. It was concluded based on present findings that calibrated bare and coated seeds should be used in planting process of black carrot seeds of Ereğli local population. Farmers should be trained on black carrot seed production.
