Variation of colour and selected physical and mechanical properties related to artificial drying of sawn silver birch (Betula pendula Roth) timber from plantations. ...

We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a...

We used in vitro callus and shoot cultures as target material for genetic transformation of silver birch (Betula pendula Roth) by particle bombardment. Cultivation of in vitro shoot cultures before particle bombardment and a long selection period, combined with a high concentration of selective agent after bombardment, led to the production of transformed plantlets that were stable, and no esca...

In declining broadleaf forests in western Ukraine, several Phytophthora species including P. plurivora, bilorbang, polonica, gonapodyides and cactorum were recovered using soil baiting assays identified morphological molecular methods. Pathogenicity tests of selected isolates performed on black alder (Alnus glutinosa (L.) Gaerth.) silver birch (Betula pendula Roth.) to assess susceptibility the...
