Early flowering together with small size would be useful for various biotechnical or genetic studies on trees. We report here the selection and micropropagation of early flowering birch (Betula pendula) clones (BPM1–12) obtained from seeds of birch

A field trial of 15 transgenic birch lines expressing a sugar beet chitinase IV gene and the corresponding controls was established in southern Finland to study the effects of the level of sugar beet chitinase IV expression on birch resistance to fun

Summary The aim of this study was to screen Scots pine embryogenic tissue culture material to Gremmeniella abietina. According to the results Scots pine (Pinus sylvestris) embryogenic tissue lines (27 lines) could be ranked based on significant diffe

Publikováno v: Forest Pathology. 27:291-300

Summary The number of airborne deposits of the root pathogen Heterobasidion annosum was counted with a wood disc method at distances 5–1000 m from one S-type and one P-type infection centre in stands of Picea abies in June, July and August, 1995. T

The effect of two stilbene compounds, pinosylvin and resveratrol, on the growth of several fungi was evaluated in plate tests. Wood decay tests were carried out with birch and aspen samples impregnated with the two stilbenes. In plate experiments, re
