In the article we have conducted the estimation of
breeding population of salix acutifolia. We have
studied the following indicators of the measured trees:
the percentage of salicylates, bark content in relation to
the wood. For these two indices we have calculated the
"complex" productivity of the trees. Based on that, the
trees are assigned to these breeding categories:
Category 1: trees with high productivity - ( 49.7 - 39.9
kg / t of raw materials) Category 2 : trees with average
productivity - ( 39.1 - 33.8 kg / m raw materials)
category 3 : trees with low productivity - ( 31.8 - 24.3
kg / t of raw materials)
In order to identify high-genotypes in natural stands of
Sacutifolia Willd we worked to identify the categories of breeding trees. Experimentally proved, that for breeding to increase the productivity of bark of Salixacutifolia Willd the selection would be best carried out with plants, the diameter of the barrel of which is in the range of 9 to 16 cm, tree age 15 - 19 years
The researches have been conducted for the optimization of culture medium for unique genotipes of Populus tremula L. in vitro. It was found that for induction of proliferation of the arms of Populus tremula in vitro one should use MS culture medium with 0,1 ml / l IBA and 0,1 or 0,5 ml / l BAP. For stimulation of rhizogenesis MS culture medium with 0,3 ml / l IBA should be used
