The increases in temperature have recently allowed the southern pine beetle (Dendroctonus frontalis Zimm.; SPB) and its associated fungi to expand its natural range to northern pine forests. In this study, vigorous eastern white pine mature trees were used to evaluate constitutive and induced response to the southern pine beetle, using O. minus as a proxy. We evaluated histological and Cited by: 2. Start studying MDA Mod E unit 4 review final. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

This indicates a change-of-phase, a trait of the resin unique to pine. The ’s- remember the gas lines- were America’s first “Solar Age.”.

Resin ducts may form either constitutively (‘normal’ ducts) or in response to injury (‘traumatic’ ducts), such as in bark beetle attacks (arrow, Figure 33(a)).Normal resin ducts occur singly, and are relatively longer compared to the traumatic resin ducts that tend to be shorter and to occur in groups.

In pines, oleoresin (hereafter resin) is a primary defense other conifers indicates that resin defense characteristics such as flow rates and chemistry are heritable genetic traits and thus subject to selection from insects, pathogens, and resin duct number, density, and size, along with tree growth.
The present book has been published having in views the important uses of pines. The book contains manufacturing process of different products extracted from pines like oleoresin, rosin, turpentine derivatives, tall oil, resins and dimer acids etc.

Resin duct production was measured as a count of resin ducts per annual ring observed. Resin duct production is the mean number of resin ducts present within an annual ring, unadjusted for the area sampled, and represents a relative measure of tree carbon investment in resin ducts.
We cal-culated resin duct density by dividing the resin duct pro. The impacts of climate and competition on large sugar pine growth and defense have potential implications for tree mortality. Slow growth and other patterns often indicate a higher probability of mortality [23,24,25,75].

Resin producing pines Virtually all pines will yield resin if tapped. Key factors that determine the feasibility for tapping are the quality (terpene content) and quantity of resin obtained.

resin/oleoresin yields two industrially valuable chemical products namely the essential oil also known as oil of turpentine, and a non-volatile product, termed as rosin. More than -Pinus species are known to exist; only very few are tapped commercially as a source of .Gel time for a given resin depends on initiator level, promoter level, second promoter level, and temperature.
