Propagation of Hazelnut by Mound Layering

The objective of this study was to determine the propagation performance of the hazelnut cultivars; Tombul, Palaz, Fo？a, Cavcava, Uzunmusa, Kal？nkara, ？ncekara and Sivri by mound layering (stooling) between 2013 and 2015 years. 6 old bushes with 5-6 stools are used as stock plants and 20 stool shoots are used per bush. This research has been repeated on the same stock plants two years in a row. In the first year, control, bud removal, bark removal and girdling treatments have been conducted. In the second year, control, bark removal + girdling and IBA + girdling have been applied. In terms of rooting and stool shoot development traits that are examined, Tombul, Palaz, Fo？a and Kal？nkara cultivars has had the highest results. Girdling treatment has performed the highest effect among all other treatments. The treatments have had various effects depending on the cultivars and treatment combinations. Rooting percentage has varied between 14.44% and 80%, rooting grade has varied between 1.08-4.533, primary root number has varied between 3.17 and 38.97, primary root length has varied between 6.44cm and 25.53cm, fresh root weight has varied between 0.307 g-9.556 g, dry root weight has varied between 0.183 g and 4.378 g, shoot length has varied between 49.65 cm and 122.65 cm, shoot diameter has varied between 6.01 mm ile 11.11 mm, bud number has varied between 11.60 and 28.26, fresh shoot weight has varied between 9.43 g and 74.35 g, dry shoot weight has varied between 4.78 g and 39.37 g and the leaf area has varied between 56.15 cm2 and 126.06 cm2. In the study, great success has been achieved during 2013-2014 period however stool shoot development and root quality has been low during 2014-2015
