DEVELOPMENT OF CRITERIA FOR SELECTION ESTIMATION OF SALIX ACUTIFOLIA FOR THE CONTENT OF BIOLOGICAL ACTIVE SUBSTANCES
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)
