Özet

European yew (Taxus baccata L.), native in North and Central Europe, Mediterranean countries, Azores, Turkey and Caucasus, has a wide range of uses as a non-wood forest product. Because the species is reduced in nature as a result of widespread utilization, it is necessary to protect and reproduce yew. The effects of different greenhouse media, rooting media and hormones were investigated on propagation by cutting of European yew. For the experiment, three greenhouse media (Greenhouse-1 media with air temperature at 20 +/- 2 degrees C, rooting table temperature at 20 +/- 2 degrees C, Greenhouse-2 media with air temperature at 20 +/- 2 degrees C, rooting table temperature at 25 +/- 2 degrees C and Greenhouse-3 media without temperature adjustment), two rooting media (perlite and peat) and four hormones (IBA 1000 ppm, IBA 5000 ppm, NAA 1000 ppm and NAA 5000 ppm) were determined in the present study. The rooting percentage, callus percentage, root length and the number of roots were determined. The results showed that the highest rooting percentage was 80% in IBA 5000 ppm treatment in perlite rooting media of Greenhouse-2 media. It can be suggested that the rooting table temperature should be 5 degrees C higher than the air temperature, perlite rooting media and 5000 ppm dosage of IBA hormone should be used for high rooting success.
