Alıç (Crataegus monogyna Jacq.) fidanlarının morfolojisi ve kök gelişme potansiyeli üzerinde yetiştirme sıklığının etkisi

In this study, the effects of seedbed density on one year-old hawthorn (Crataegus monogyna Jacq.) seedlings characteristics (root collar diameter, seedling height, shoot and root dry weights and root/shoot ratio) and root growth potential were investigated. Five different seedbed density (control, 3, 6, 9 and 12 cm) were applied in Egirdir Forest Nursery. As a result, different seedbed density were significantly affected root collar diameter, seedling height, shoot and root dry weights except root/shoot ratio and root growth potential. The highest root collar diameter, seedling height, shoot and root weights were obtained from seedling which is grown with 9 and 12 cm seedbed density while control seedlings had lowest in nursery. Under conditions of Egirdir Forest Nursery, seedlings should be thinned to 6 or 9 cm in distance to produce taller seedlings with larger diameter.
