The selects of bearberry (arctostaphylos uva-ursi (l.) Spreng.) From natural populations in Poland

Abstract

Five plants of bear berry selected from nalural stands in Poland and one from a Botanical Garden were propagated by cuttings. The clonal plants were first kept under observation for two years planted on different substrates in containers and were afterwards field cult vated for three subsequent years. The existence of a significant differentiation within these Arctostaphylos uva-ursi clones was proved. Two selects of good ornamental features as well as with high concentration of medicinal sub stance -Arbutin were chosen. Plants started fruiting in the fourth year of growth and the area covered by a single plant exceeded 2 m after five years of cultivation.,.
