Genetic and correlation analysis of oleoresin chemical components in slash pine.
This is the first comprehensive study of the genetic analysis of the majority of oleoresin components of slash pine (Pinus elliottii). Pine oleoresin, the resin secreted from the pine tree, is a raw material widely used in industrial products. The objective of this study was to explore the genetic variation and correlation between the major oleoresin components of 50 open pollinated families of...
متن کاملAluminum sensitivity of loblolly pine and slash pine seedlings grown in solution culture.
To probe variation in Al sensitivity of two co-occurring pine species, seedlings from six full-sib families of loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) were grown in solution culture containing 4.4 mM (high-Al) or 0.01 mM (low-Al) AlCl(3) at pH 4 for 58 days. On average, both pine species had 41% less total dry weight in the high-Al treatment than in the low-Al tr...
متن کاملChemicals and biofuels from pine oleoresin
Coniferous trees are rich in chemical compounds such as terpenes, fats/fatty acids, waxes, tannins and phenolics, which function to protect the tree against insect pests and diseases, and as energy reserves. Compounds extractable with organic solvents typically comprise about 3 to 5 percent of total biomass on a whole tree dry basis, and may represent up to 25 percent in certain tree parts, suc...
متن کاملTop Grafting Longleaf x Slash Pine F1 Hybrids on Mature Longleaf and Slash Pine Interstocks
-Top grafting is used to accelerate the breeding cycle of loblolly pine (Pinus taeda L). Scions, collected from seedlings as young as 1 year from seed, are grafted onto mature interstocks of the same or a related species. Male and female strobili production often begins 1 or 2 years after grafting, thus potentially decreasing the generation time by several years over conventional accelerated br...
متن کاملDefense response in slash pine: chitosan treatment alters the abundance of specific mRNAs.
We used differential display to identify chitosan responsive cDNAs in slash pine cell cultures. Two clones that showed increased mRNA abundance had sequence similarity to genes with roles in major plant defense responses, clone 18 to cinnamic acid 4-hydroxylase, and clone 30 to chitinase.
