Abstract

Seeds of ten different Betula species were treated with colchicine solution during germination, to induce duplication of the chromosome set. The species included in the study were B. pendula, B. pubescens, B. papyrifera subcordata, B. papyrifera papyrifera, B. papyrifera occidentalis, B. populifolia, B. alleghaniensis, B.n igra, B. glandulosa and B. nana. The total number of individually labelled, colchicine-treated trees was 1,550. Colchicine treatment induced changes in morphological features, especially in the leaves. These features proved to be good indicators of polyploidization. The experiments produced 687 polyploid trees, 287 of which are still alive. The polyploid Betula trees offer possibilities of studying the significance of the genome dosage for the growth, breeding, adaptability and evolution of Betula.
