      As plant material has great visual and functional importance and it is often used within landscape architecture, it can be easily said that it is one of the most important physical components of landscape architecture and landscape planning. Owing to recent improvements in biotechnology and gene researches, it is possible to use any plant species more easily and in the desired quantity. In this research, a native species of Black Sea Region of Turkey, Sorbus torminalis L.Crants, was examined as an important plant material for landscape architecture and some information regarding its vegetative and generative seedling methods and its adaptation to the outer media were provided for the implementers.

This study performed in four stages. In the first stage, the determination of Sorbus torminalis L. Crantz seeds’ stratification process (cold stratification and acid process application) , in the second stage, determination of taking root percentages from Sorbus torminalis L. Crantz’s soft and hard cuttings, in the third stage, production of Sorbus torminalis L. Crantz’s embryos and buds with the method of tissue culture in the MS-LS media and the adaptation of the seedlings to the environment, then in the last stage, searched for determination of the importance for Landscape Architecture.

       In generative and vegetative production, while there was germination in Sorbus torminalis L. Crantz seeds which taken to cold stratification for 120 days, germination was not seen mostly in other prosess. In the study of soft steel production, there was rooting in the forest soil having %16.6 percent of IBA hormone though, there was not any rooting in the production of hard cutting. In the tissue culture study, it was ascertained that the most perfect development was in MS and LS areas 3mg/l BAP+1mg/l Kinetin dosed combinations, the most perfect shoot length and shoot number were in MS 3mg/l BAP+1mg/l Kinetin area, the most perfect rooting was in the LS 3mg/l BAP+1mg/l Kinetin area, the most efficient hormone was IBA in rooting of micro steel, the most perfect dose was 1mg/l, the most perfect area was ½ MS area with %56,6 percent of rooting and the most perfect mixture of adaptation to the soil were 2:1:1forest soil: sand : perlite mixture.
