Stocktype impact on survival and growth of one-year old Quercus pubescens seedlings on the edge of Panonnian basin Utjecaj tehnologije proizvodnje na preživljavanje i rast jednogodišnjih sadnica quercus pubescens na rubu Panonskog bazena Jovana Devetaković, Milutin Đilas, Ivona Kerkez Janković Summary Querqus pubescens has relatively wide distribution in Europe, but dominated forests are quite common in South Europe, while they are confined to warm microclimatic conditions in central Europe. On the edge of the Panonnian basin Q. pubescens is mainly found on the edge of its native range, in isolated populations which have an important role in examining the adaptive potential, especially considering that the forest-steppe and sub-mediterranean climate is predicted to be the dominant climate in some regions of Central Europe in future. There are very limit knowledge about Q. pubescens forest establishment and restoration in continental climate today. This study provides information about stocktype effect on seedlings success after outplanting in very competitive conditions. Although bareroot seedlings were larger in the nursery, container seedlings had better survival and growth on the field. Generally, low survival rate for both stocktypes (mean survival 47.60 %; container seedlings 55.41%; bareroot seedlings 41.41%) can be assessed as consequence of uncompetitive seedlings and lack of vegetation control. Key words: stocktype, survival, growth, lack of vegetation control, restoration Introduction Uvod Oak forests are represented for the most part of Balkan Peninsula and Southeast Europe, but their condition and perspectives are related to composition of species and ecological conditions which vary from site to site. According to last forest inventory in Serbia, about 30% of forest area belongs to oaks forest, while more than half of them are coppice forest (Banković et al., 2009). One of native oaks in Serbia is Pubescent or Downy oak (Quercus pubescens Wild.) which is frequent member of polydominant oak forests, but with significant lower distribution then Q. cerris, Q. petraea, Q. frainetto and Q. robur (Cvjetićanin et al., 2016). Since Q. pubescens is mainly distributed in central and southern Europe and it is one of the most important forest tree species in south-central and south-eastern Europe and Anatolia (Bordács et al., 2019), so majority of data for Q. pubescens seedlings field performance are available for Meditteranian region. Q. pubescens dominated forests are quite common in South Europe, while they are confined to warm microclimatic conditions in central Europe |
