MEMLEKETİMİZİN DOĞAL AKÇAAĞAÇ (Acer L.) TÜRLERİNİN ODUNLARININ ANATOMİK ÖZELLİKLERİ İLE YETİŞME YERİ ARASINDAKİ MÜNASEBET

In the course of the taxonomical study on the macro- and micro -morphological charasteristisc of Acer species in Turkey (Yaltırık, 1968) a significant relation between anatomical characteristics of woods in studied Maples and their growing sites was clearly observed. The folio wig 19 taxa under 9 species occur naturally in Turkey: 1 — A. hyrcanum F. et M. (subsp, hyrcanum, subsp. keckianum (Pax) Yalt., A. sempervirens L., 5 — A. monspessulanum L. (subsp. monspessula-num, subsp, microphyllum (Boiss.) Bornm., subsp. ibericum (Bieb.) Yalt., subsp, cinerascens (Boiss.) Yalt., subsp. oksalianum Yalt.,), 6 — A. hyrcanum F. et M. (subsp, hyrcanum, subsp. keskianum (Pax) Yalt., subsp, tauricolum (Bois.) Yalt., sphaerocaryum Yalt.), 7 — A. campestre. (subsp. campestre, subsp, leiocarpum (Opiz) Pax.), 8 — A. cappa-docicum Gledt. (var. cappadocicum, var, stenocarpum Yalt.), 9 — A. divergens Pax (var. divergens, var trilobum Yalt.), (Map 1). In the point of the ecological demants and site characters of Turkish Acer species, they almost are found as small groupes or singly on the whole forest areas in Turkey, under the different solis and climatic conditions (such as in N. Anatolia with humid or perhumid climate and asid soils whereas, in S. Anatolia with alkali, lateritic soils which ise on the limestone rocks, and the climate with the summer droughts), in the different stand types of the forests (such as pure or mixt stands point of the tree species), in the different altitudes (form sea level to above tree line, 2400 m.).A strong relation between the vessel diameters, the number of the vessels in a unit cross sectional area and the moisture relations of the growing sites was found out in this study.
