Abstract:

Abstract Mortality due to annosus root rot among trees of seven species on two sites was 6% or less by age ten. Previous stands on these sites had been clearcut because the disease was widespread. After 22 years neither basidiocarps of Heterobasidion annosum nor trees with symptoms of annosus root rot were present in the plantations. Planted seedlings of loblolly (Pinus taeda L.), longleaf (P. palustris Mill.), slash (P. elliottii Engelm. var. elliottii), and eastern white (P. strobus L.) pines survived well and at age 22 provided fully stocked to overstocked stands with good basal area and av

Abstract:

This study investigated the origins and spread patterns of Heterobasidion root disease in three Pinus contorta Dougl. ex Loudon plantations established on forest and agricultural land and subjected to three different management scenarios. Trees with decline symptoms and stumps remaining from the previous rotation were sampled for fungal isolations. Ten isolates of Heterobasidion parviporum Niemelä & Korhonen and 425 of Heterobasidion annosum (Fr.) Bref. were tested for clonality through somatic compatibility tests.

High inoculum concentrations (107 spores/mL) were also required for rapid colonization and establishment of the pathogen in the cortex.

Abstract:

В условиях Архангельской области преобладают хвойные леса, в первую очередь насаждения ели европейской (Pícea ábies), которые подвергаются активному хозяйственному освоению. Одной из причин снижения товарности еловых древостоев является воздействие дереворазрушающих грибов. В еловых насаждениях района исследований наиболее распространены базидиальные грибы: корневая губка (Heterobasidion annosum (Fr) Bref), и еловая губка (Phellinus chrysoloma), вызывающие пеструю коррозионную ядровую комлевую и стволовую гнили. Болезнь приводит к потере части деловой древесины, вызывает образование бурелома и

Abstract:

Pacific silver fir (Abies amabilis Douglas ex J. Forbes) was first introduced to Britain in 1830 but has not been widely planted and occupies a minute part of the forest estate. The results of six experiments established in the uplands of Britain examining material from 30 collection sites in 14 seed zones clearly demonstrate that its potential has not been recognised. The trials were assessed after 28 years and show that Pacific silver fir has the potential to be as productive as other common species options. There was little variation in performance between the 14 seed zones, and future seed

Abstract:

In the mountain pine (Pinus mugo subsp. uncinata (DC.) Domin) forests of the Swiss National Park in the Central Alps, disease centers associated with the root-rot fungi Heterobasidion annosum (Fr.) Bref. and Armillaria spp. are characteristic elements. We assessed the impact of these pathogens on forest dynamics by studying transects running across disease centers into the adjacent forest. Overall, mountain pine was the most abundant regenerating tree species and accounted for 84% of all seedlings (<20 cm high) and 93% of all saplings (20–130 cm high), whereas Swiss stone pine (Pinus cembra

Abstract:

Erwinia billingiae S31R1 and Bacillus simplex S11R41, isolated from the rhizosphere of a healthy tree located in a Pinus radiata D. Don plantation with high presence of fungal pathogens, are antagonists of pine root rot fungi Heterobasidion annosum and Armillaria mellea in vitro and in young trees. For effective biocontrol of these pathogens, the bacteria must stably colonize P. radiata roots following their application. To determine root colonization patterns, the bacteria were transformed with stable plasmids encoding green fluorescent protein (GFP). Transformed E. billingiae was visualized

Abstract. Various biotic and abiotic stresses are threatening forests. Modern remote sensing technologies provide powerful means for monitoring forest health, and provide a sustainable basis for forest management and protection. The objective of this study was to develop unmanned aerial vehicle (UAV) based spectral remote sensing technologies for tree health assessment, particularly, for detecting the European spruce bark beetle (Ips typographus L.) attacks. Our focus was to study the early detection of bark beetle attack, i.e. the “green attack” phase. This is a difficult remote sensing task

Abstract:

Pine stands affected by root and butt rot (Heterobasidion annosum s.l.) contain pines (Pinus sylvestris L.) that can survive for a long time without showing external symptoms of the disease (‘conditionally resistant’ refers to trees that survive without symptoms despite infection). The establishment of stands from the seeds of such trees can significantly increase the effectiveness of artificial afforestation. Since the growth and development of pine trees is determined to a certain extent by the number of cotyledons after seed germination, this article examines this trait in the progeny of tr

The development of wood decay caused by 12 major root-rot and trunk-rot fungi was investigated in vitro with sapwood extracted from nine ornamental and landscape hardwood and conifer species native to southern temperate regions of North America, Europe, and the lower Mississippi Delta. Wood decay rates based on dry weight loss for 108 host tree–wood decay fungi combinations were compared at 21 °C over 1-year and 2-year incubation periods in the absence of tree-resistance mechanisms. Strains of Armillaria mellea, Ganoderma lucidum, and Heterobasidion annosum exhibited the highest decay potentia
