Abstract
The research was performed to determine the effect of planting depth on plant development characteristics in grape hyacinth growing (Muscari armeniacum Leichtlin ex Baker). In the experiment, grape hyacinth bulbs with a circumference of 3.5 cm were used as plant material. Grape hyacinth bulbs were planted in the mixture of perlite + peat + cocopeat (1: 1: 1) at a depth of 1 cm (superficial planting), 4 cm (medium depth planting) and 7 cm (deep planting). After planting, bulbs were irrigated until the leaves formed, and then nutrient solution was applied. The experiment was designed as a randomized plot design with three replications with 10 bulbs each (pot). In the experiment, biometric measurements including emergence number, EC, pH, plant weight, bulb diameter, weight, bulblet number, adventitious root number, length, weight, leaf number, length, width and weight were determined. The data was applied to variance analysis (ANOVA) and Duncan multiple comparison test (p=0.05). According to statistical analysis; at the end of the 2nd week, the highest emergence rate (50%) from bulbs planted in superficial planting, and the highest plant weight (3.79 g) from bulbs planted in medium depth planting were obtained. The effect of planting depth on the other parameters was insignificant. The bulb diameter was 14.37-15.42 mm, the bulb weight was 1.79-2.11 g, the bulblet number was 1.00-1.40, the leaf length was 22.88-24.50 cm, the leaf width was 3.64-3.81 mm and adventitious root length was between 8.56-11.50 mm.
