We examined the interaction between the roots of Pinus sylvestris and closely related species Heterobasidion annousum s.l. (H. annosum s.s., H. parviporum, H. abietinum) that differ in host plant preference. The aim of the current study was to determine in roots the accumulation pattern of low molecular mass compounds such as catecholate and hydroxamate derivates, oxalic acid as well as iron-reduction...
The aim of this work was 1) to investigate the genetic diversity of H. annosum s. str. populations, 2) to recognize genets ability of their aggressiveness to Scots pine. The genetic similarity among genets varied from 0% to 74%. Totally different genets were found in 17.9% of cases. The lowest similarity occurred among 20.7% of genets and it was calculated on 18%. Six months after inoculations of...
The aim of this study was the analysis of H. annosum s. s. stand infection and also the stumps colonization by P. gigantea and H. annosum a year after stumps inoculation with biopreparation. The study was conducted in 40-year-old Scots pine stand growing on the post arable soil, where two plots had been established. After commercial thinning the stumps treatment with P. gigantea was done. There were...
The aim of this study was to analyse genetic diversity of H. annosum s. s. population in selected Scots pine stands with planted beech as a second floor or understorey, in Bolewice and Tuczno Forest Districts. In these stands the 14 genets of H. annosum s. s. were recognised. The biggest genet occupied 84 m2 and the smallest one colonized only one beech. The beech was attacked by pathogen similarly...
