ABOUT SPLITTING OF THE DECORATIVE SIGN IN THE FIRST GENERATION OF THE ELM SPHERICAL
About splitting of ornamental feature in the first generation of spheroidal elm. It is excellently clipped and keeps artificially made form very well. However, its ornamental forms of crown are the most valuable, one of which is spheroidal – f. umbraculifera (Trautv.) Rehd. It may under do splitting and losing its ornamental features under seed propagation. The task of our study was to evaluate the results of splitting of this ornamental peculiarity in seed propagation. The results of the analysis show that evident relationship is established between, the increasing of the average diameter of seedlings and the number of sprouts during the first year, described by the equation. B = 0.2070+0.8490*A. (r =0.9819). The total sum of regrowth is of special importance in creating spheroidal form. Essential value begins to form in the group of sprouts from 21 to 30, gaining the largest value in the group of 41to 50 sprouts. Increasing the regrowth gum is described by the equation C=28.9000+54.3400*A (r=0.967). Seedlings with the number of sprouts from 11 to 20 occupy the dominant position by the share of participating in the total seed offspring of the first spheroidal form generation, 24 % is the group of 21 to 30. It is defined that during the first year the number of sprouts may be used as the diagnostic feature of ornamental form. The seedlings that have kept their spheroidal form of crown have the number of sprouts from31 to 40. This group in the total offspring makes 4 %.
