Olive 'Gemlik' has been planted in different ecological zones in Turkey; growers have begun to focus on some problems of yield and quality, and they would like to use grafting (top-working) with local cultivars. Although there is no problem of grafting compatibility between cultivars according to the literature, it has proved very difficult to give advice to growers for top-working because problems have been encountered when grafted local cultivars onto 'Gemlik' rootstock. The plant material used in this study consisted of cultivars 'Ayvalik', 'Domat', 'Gemlik', 'Memecik', 'Nizip Yaglik' and 'Sari Ulak'. These cultivars were grafted (T-budding) onto 1-year-old 'Gemlik' rootstock propagated by cuttings. According to the results of phenolic compound variance analysis, high levels of 4-hydroxyphenylacetic acid, vanillic acid and ferulic acid content were determined in 'Ayvalik', 'Nizip Yaglik' and 'Domat'. As a result, we showed that, during recovery of the graft zone, development of new cambium tissues, vascular connections and sclerenchyma tissues occurred imperfectly in 'Ayvalik', 'Domat' and 'Nizip Yaglik' when grafted onto 'Gemlik' rootstocks. For this reason, the graft zones of these combinations were weak.
