Background & Aim: The most therapeutic properties of different species of Pinus class are antimicrobial and anti-inflammatory characteristics, soothing effect, resolver of skin itches, wound, acne and rash healer and improvement of ulcers and chronic lesions. In ancient medical literature of Iran, different parts of Pinus classes, particularly its resin, had been used for treat...

The resin tapping history of an Aleppo pine (Pinus halepensis ssp halepensis) forest in Northern Evia, Central Greece was investigated by standard dendrochronological methods. Cross-sections disks of tapped and non-tapped trees were taken from a representative, concerning structure and management, Aleppo pine stand. The identification of resin tapping scars in the cross-sections, combined with ...

-We evaluated selection of nest sites by male Red-cockaded Woodpeckers (Picoides borealis) in Texas relative to the age of the cavity when only cavities excavated by the woodpeckers were available and when both naturally excavated cavities and artificial cavities were available. We also evaluated nest-cavity selection relative to the ability of naturally excavated cavity trees to produce resin,...

The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...

afghan pine one of the native tree species in eldar region of azerbaijan republic. fast growing, suited for dry climate condition, increasing wood in unit volume, reason of using eldar pine in reforestation and plantations. at this case study of absheron peninsular of baku, azerbaijan, were taken 14 trees samples of two sites. bbg, baku botanical garden and bmd, baku merdakandendrary, are two c...

Many forest ecosystems with a large pine component in the western United States have experienced environmental stress associated with climate change and increased competition with forest densification in the absence of fire. Information on how changes in climate and competition affect carbon allocation to tree growth and defense is needed to anticipate changes to tree vigor and, ultimately, sta...

Tapping technique comprises the extraction of pine oleoresin, a non-wood forest product consisting of a complex mixture of mono, sesqui, and diterpenes biosynthesized and exuded as a defense response to wounding. Oleoresin is used to produce gum rosin, turpentine, and their multiple derivatives. Oleoresin yield and quality are objects of interest in pine tree biotechnology, both in terms of env...

Introduction Tree defense characteristics play a crucial role in modulating conifer bark beetle interactions, and there is growing body of literature investigating factors mediating tree growth resin-based defenses conifers. A subset studies have looked at relationships between growth, resin duct morphology climate; however, these are almost exclusively from lower-elevation, moisture-limited sy...

Resin flow is the primary means of natural defense against southern pine beetle (Dendroctonus frontalis Zimm.), the most important insect pest of Pinus spp. in the southern United States. As a result, factors affecting resin flow are of interest to researchers and forest managers. We examined the influence of fertilization, artificial wounding and fungal inoculation on resin flow in 6- and 12-y...
