【 摘 要 】

The medicinal use of linden species (Tiliasp.) in traditional folk medicine has been known for centuries. It is one of the most consumed herbal teas, especially in winters. A large part of the production is obtained from natural silver linden (Tilia tomentosaMoench.) forests in Bursa and Yalova provinces. Since there aren’t any plantations for flower production, production from natural forests creates extreme damages. To prevent this destruction, it is necessary to establish flower production plantations where the high-quality flowers are selected and clonal propagation performed. It is seen that in natural populations, flowering time, flower color, bigness, odor, etc. vary. In this study, The oil amounts of samples collected at the full blooming time from Bursa-Gökçeören, Karacabey-Yeniköy and Yalova-Esenköy Natural Populations were determined using Clevenger apparatus. The factors such as location, altitude, aspects, slope, crown aspect, flower color, affecting the oil yield were investigated. Finally, Correlations between oil amounts and physiographic factors were examined.As a result of the study; It was determined that the oil yield of the linden flowers varies according to the location and the altitude, while the slope and aspects showed no effect. It was also found that crown closure, tree crown diameter, crown aspect, flower color, bud, and full blooming did not affect the oil yield.
