Investigation of the effects of arb uscular mycorrhizal fungus inoculation on growth performance and adaptation success of oriental beech (Fagus orientalis Lipsky.) seedlings

In the thesis study, arbusular mycorrhizal fungus vaccination was performed in the oriental beech (Fagus orientalis Lipsky.) seedlings, the tubular seedlings applied and not applied to mycorrhizae will be planted in 3 different elevation stages (200-400 m, 400-600 m and 600-800 m) in Yenice region and the field performances were monitored. Comparisons were made both within and between the elevation stages and quantitative characters (elevation, height, root throat diameter, seedlings fresh weight, seedlings dry weight, root length, number of side roots and percent of survival) were measured in the nursery. As a result of the measurements, comparisons between Mycorrhiza and control seedlings were made with the help of variance analysis and Duncan test, and characters that are significant at least 95 % confidence level are given together with homogeneous groups formed among themselves. As a result of comparisons made with control seedlings after AMF application in the study, the mean height growth in the whole sample plots 30,01-43,56 cm, root collar diameter 0,52-0,85 mm, seedlings fresh weight 7,97-9,07 g, it was determined that seedlings dry weight 4,45-6,52 g, root length 22,77-31,39 cm, the number of side roots ranged between 6,10-14,80 pieces and the percentage of survival 62,54-95,12 %. In all morphological characters and percentages of survival studied at all elevation levels, the seedlings with AMF provided superiority to the control seedlings. Especially in the percentage of survival variable, it was determined that oriental beech seedlings, where AMF was applied, had a superiority of nearly 30 % compared to control seedlings.
