Özet
Mastic tree (Pistacia lentiscus var. chia Duham.) is an important medicinal aromatic plant which is being culti-vated without any regular fertilization generally. Foliar Zn applications have great importance for many com-mercial plant species because of their important role in metabolic activities. In this study, the effects of foliar ZnSO4 sprayings (0, 0.2, 0.4, 0.8%) applied at 50% and 100% leafing stages, on some yield parameters and essential oil composition of mastic tree were assessed. A field experiment was carried out for two consecutive years at Ege University, Turkey. Mastic resin yield was more than doubled with 0.8% Zn particularly in the second year. The highest leaf Zn content was measured as 187.8 mg l- 1 with 0.8% zinc spraying while it was 35.4 mg l- 1 in unsprayed trees at 100% leafing in the first year. Leaf essential oil and alpha-tocopherol contents were not significantly influenced by different Zn levels and leafing stages in both years. As for the major essential oil constituents, 13-myrcene (62.4%), germacrene-D (14.3%), alpha-terpinenyl acetate (5.52%), t-caryophyllene (2.1%) and alpha-pinene (1.4%) were determined. Zinc sprayings increased the 13-myrcene, germacrene-D and alpha-pinene contents particularly at 100% leafing in the first year. In mastic tree two consecutive applications of Zn seems to be necessary for reaching to desirable leaf Zn contents. Application of 0.8% Zn or more would be proper to increase the contents of most parameters assessed.
