Abstract
The effect of potassium humate on seed germination was studied in ‘Tombul’, ‘Palaz’, ‘Sivri’, ‘Çakildak’ and ‘Kalikara’ hazelnuts in Ordu province in 1999-2000. Nuts were cracked and kernels treated with water as a control, or with potassium humate (120 g/L) at three concentrations (0.01 ml, 0.02 ml, and 0.03 ml/seed) for two lengths of times (12 and 24 hours). The seeds were then sown in perlite, and seed germination percentage and germination period recorded.
Differences among cultivars for % germination and germination period were significant for cultivars and dosage, but not for time.
The highest germination percentage was 64.17 % for Çakıldak, and the lowest was 37.08% for Kalınkara.
The germination percentage was highest (53.33%) for the 0.02 ml/seed treatment, and 43.00% in the controls.
K-Humate treatments increased the germination percentages, and prolonged the germination period.
The 0.02 ml/seed of K-humate treatment is recommended for the highest germination percentage.
