The creation of small-leaved lime planting stock (Tiliacordata) in the conditions of south forest-steppe of the Omsk region
Small-leaved lime ( Tíliacordata) iswondeful species of trees, producing honey. This tree species is not cultivated in forest tree nurseries of Head forestry department of the Omsk region for the purpose of an artificial reproduction. Small-leaved lime grows wild in BolshyiUki, Ust-Ishym and Tevris areas. This forest is the basis for a honey production. Small-leaved lime occupies a very small area, which equals 1.5 ha. Natu- ral reproduction of small-leaved lime in the Omsk Pryirtysh district is a reliquiae. Questions of reproduction of small-leaved lime haven’t been studied yet. Shoots cloning of small-leaved lime has an important practi- cal value for areas of natural reproduction. A technology of seed reproduction has not been developed for the Omsk region. Complexity of the matter is in the existence of a long and deep physiological quiscent period of small-leaved lime seeds. Experimental facts of small-leaved lime seed reproduction has been describedin this article. Results of measuring of height and root neck diameter of one-, two- and three-year old plants have been shown. It has been shown that seedlings received from small-leaved lime growing in the Оmsk State Agrarian University Dendrology Park have large variation in the growth and development parameters.
