Özet
Effects of root undercutting in the seedbed and seed size grading on a variety of seedling morphological traits of sessile oak (seedling height, seedling diameter, root dry weight, shoot dry weight, number of large lateral roots > 1 mm and number of fine lateral roots < 1 mm) were studied at Ardanuc Forest Nursery, Artvin, Turkey. The growth and dry weight of 1+0 bareroot sessile oak seedlings were observed higher for the seedlings raised from acorns of medium and large sizes. Time of undercutting affected seedling morphological attributes, and undercutting in July produced greater seedlings from acorns of medium and large size class (for both height and diameter) that had greater numbers of large lateral roots compared to the other undercutting treatments. When averaged over three acorn sizes, undercutting increased shoot dry weight, number of large lateral roots and fine lateral roots. This study suggests that undercutting treatment and acorn sizing appear to be tools to the nursery manager to produce larger sessile oak seedlings in the nursery.
