Abstract

Monumental tree. or also called as uncommon tree is separated easily than common trees by biological, habitus and historical, which is a natural resources and part of daily life of people. These differences and their locations make compulsory in conservation and awareness of nature. The trees have also a link between history and biology because of their older ages, and also genetic reserve together with social-cultural importance. To transmit these link and importance can be by generative or vegetative propagations from monumental trees. However, vegetative propagation has many advantages to generative propagation in the transmitting such as loss of genetic diversity. In this context, hard and softwood cuttings were sampled, from a monumental tree which had the one of the oldest common yew (Taxus. baccata L.) trees in the world and the oldest tree of Turkey by about 4000 years, in April and August of 2017. The cuttings treated by 0.1%, 0.3% and 0.5% doses of Indole-butyric acid (IBA) were rooted in perlite medium in greenhouse conditions together with control group. The effect of these doses on the properties of rooting percentage, average root length and number of roots were investigated. There was no significant effect of IBA in different doses on rooting percentage, root length and root number, while sampled period of cutting was effective on rooting. The highest rooting (18%) was observed in hardwood cuttings sampled in April and treated by 0.1% IBA. Results of the study were discussed based on forestry practices such as genetics, nursery practices of the species.
