The condition of the root system affects the quality of seedlings in forestry and horticulture. Previously, the electrical impedance loss factor (δ) and the reverse-flow hydraulic conductance (K_r) of the roots of Scots pine seedlings were found to increase when assessed a few days after frost...

Cronartium orientale is a heteroecious rust fungus that causes pine gall rust of two-needle pines, e.g., Japanese black pine (Pinus thunbergii) and Japanese red pine (Pinus densiflora). Basidiospores are discharged from telia on fagaceous plants, then infect pine shoots and/or stems. To determine...

Accurate detection of mechanical components faults is an essential step for reduction of repair cost, human injury probability and loss of production. Using intelligent fault diagnosis systems in tractor could prevent secondary damage, thereby avoiding heavy consequences. In this study, fault...

Description of the subject: Although cork oak is considered highly forest fire resistant tree species, the fire is not without economic impact. The cork stripping method has become a decisive management tool for the success of economic restoration. Objectives: Evaluate the sanitary recovery of cork ...

Modification of forest trees can occur from a variety of factors. Both cultural and natural processes can injure trees and many injuries can be dated dendrochronologically. Distinguishing between types of injuries, however, is important for understanding past human land-use practices and...

Agarwood, resin produced by wounded Aquilaria plants, is widely used in perfume and medicine. In this study, artificial agarwood induced by physical injury, chemical stimulation, fungal infection, and comprehensive stimulation, which are the common induction methods, was collected. After gas...

Timber boardwalk decks are widely installed in parks and scenic areas to provide pedestrians an elevated footpath as well as harmony with the surrounding natural scene. In order to extend the lifespan of boardwalks in the outdoor environment, industrially treated pine timber, such as Pinus...

Tree stems have been identified as globally significant methane (CH₄) sources; however, little information exists on emissions from tree wounds and branches. CH₄ emissions can occur from the decomposition of anaerobic heartwood, which is also associated with wounds; CH₄ may also be transported...

The state of Taxus cuspidata (Japanese yew) population is assessed based on the data obtained during field studies in Udege Legend National Park. The most common types of trunk damages are indicated: bark injuries and drying cracks, tree-top dieback and hollows. The trees were categorized by health ...

Background: Low temperatures are known to limit the growth and geographical distribution of poplars. Although some transcriptomic studies have been conducted to explore the response of poplar leaves to cold stress, only a few have comprehensively analyzed the effects of low temperature on the...
