Résumé
There is about 5,25 million ha land area that are socially, economically and ecologically feasible for afforestation in Turkey. A considerable amount of these potential afforestation areas suffer from water deficiency during growing season. Afforestation practices in arid and semi-arid lands have been resulted limited success so far. Low survival rates and slow growth of remaining seedlings increases the cost of afforestation efforts. Thus, exclusion of these lands to animal grazing and usage of locale people increases the social friction. Data from different region around the world suggest that using mycorhizal seedling may increase the plantation success. However, Turkish forestry has not well adopted producing and using such seedlings. Thus, the aim of this study is to contribute to data generation about mass production of mycorrhiza inoculated seedlings and promotion of using such seedling in aridland afforestation. The local mycorrhizal mixture was obtained from the rhizospheres of Black locust (Robinia pseudoacacia) and Russian olive (Elaeagnus angustifolia) in afforestation areas located around Ekecik, Acıpınar, İncesu, Emirgazi, Karapınar and Meke Lake. The local mycorrhizal mixture and a commercial mycorrhizal mixtures with humic acid combinations were applied on black locust and Russian olive seedlings in a completely randomized design. To determine the treatments effects seedling variables such as root collar diameter, shoot height, leaf area index, root length were measured and leaf nutrient concentrations (N, P, K, Ca, Mg, Fe, Cu, Zn, Mn) analysed. Results of the data indicated growth variables of seedlings treated with local mycorrhizae were significantly different than those of the other treatments. It is recommended that local mycorrhizaecan be used to growing seedlings for arid regions.
