Dormant buds on Betula pubescens and Betula pendula stumps under different field conditions

Forest Ecology and Management, 1992
Abstract 1500 Stumps of pubescent birch (Betula pubescens Ehrh.) and silver birch (Betula pendula Roth) were studied in four localities in middle and southern Sweden with different site conditions. The naturally regenerated birches were 3 to 19 years old. The stumps were sampled in 15 mm diameter classes from seed-sown trees. Living dormant buds were

Discrimination between Betula pendula, Betula pubescens, and their hybrids using near-infrared reflectance spectroscopy

Canadian Journal of Forest Research, 1997
Identification of Betula pendula Roth, Betula pubescens Ehrh., and their interspecific hybrid is a long-standing problem. We present a methodology in which dried, milled leaves of a sample of the three taxa have been subjected to near-infrared reflectance spectroscopy at a broad range of wavelengths (400n2500 nm).
