Study of the growth, yield, and pest resistance of shortleaf X slash pine hybrids. [New Orleans, La.]: U.S. Dept. of Agriculture, Forest Service, Southern Forest Experiment Station, [] (OCoLC) Some hybrids exhibited an intermediate basal crook. 2 The basal crook is a bend in the stem of shortleaf pine saplings and seedlings that lowers a segment that contains dormant buds to the surface of the soil where it is covered by soil and duff.

The location of the buds below or near the soil surface helps protect them from damage due to fire and presumably facilitates resprouting.

Shortleaf pine (Pinus echinata Mill.) is an important forest tree and timber-producing species found throughout the southeastern United natural range is the largest of the southern yellow pines (subgenus Pinus, section Trifoliae, subsection Australes), extending further north and west than that of the other major species—loblolly pine (Pinus taeda L.), longleaf pine (Pinus Cited by: 4.

Our objectives were to compare survival and growth of loblolly pine, shortleaf pine, and pitch x loblolly hybrid pine planted in southeastern Oklahoma.

The study was established in spring at 4 sites in southeastern Oklahoma within the natural range of Author: K.C. Dipesh, Rodney E. Will, Thomas C Hennessey, Thomas B. Lynch, Robert Heinemann, Randal Holeman. Based on these results, we recommend that shortleaf pine yield orchard managers consider steps to mitigate the genetic impact of trees classified as either F1 or SLBC1 hybrids to maintain the genetic integrity and desired phenotypic traits (i.e., fire, drought, and ice tolerance) of their shortleaf pine seeds, ensuring survival and adaptation of Cited by: 4.

habit of shortleaf pine is a common and desirable characteristic of seedlings. It is a good indicator of genetic purity distinguishing it from loblolly/shortleaf hybrids Successful Planting of Shortleaf Pine Shortleaf pine is one of four major southern yellow pines found in the forests of NC.

Its wide range. Protocols were developed for the micropropagation of shortleaf pine (Pinus echinata Mill.), loblolly (P. taeda L.) x shortleaf pine hybrids, and Virginia pine (P. virginiana Mill.). For meristematic tissue induction, modified Gresshoff & Doy (GD) medium with a high concentration of benzyladenine (BA) and short pulse treatment was best for loblolly x shortleaf hybrids whereas a lower Cited by: Information on Shortleaf Pine, Pinus echinata, a native plant to North America.

Includes commerical and native American uses, botanical characteristics, distribution, habitat, pest and diseases, and images to help with tree species identification. Pinus echinata, the shortleaf pine, is a species of pine native to the eastern United States from southernmost New York, south to northern Florida, west to eastern Oklahoma, and southwest to eastern tree is variable in form, sometimes straight, sometimes crooked, with an irregular crown.

This tree reaches heights of 20–30 metres (65– ft) with a trunk diameter of – Clade: Tracheophytes. Demonstrating a consistent diameter growth pattern in some of its range, shortleaf pine will maintain itself in a stand once reaching the dominant or codominant crown canopy position.

Shortleaf pine is susceptible to littleleaf disease in flood-prone areas, but it does show the most resilience to. Highlands, and it is there that shortleaf management is concentrated.

Despite its importance as a resource, shortleaf has been the most neglected of the major southern pines in terms of research information. This is particularly true for growth and yield information.

There is some growth and yield data available for natural even-aged. Fire Ecology and Management of Shortleaf Pine Ronald E. Masters, Director of Research Tall Timbers Research Station Shortleaf pine (Pinus echinata) occurs across a wider variety of climates, soils, topography, moisture regimes and fire regimes and thus community types, than any otherFile Size: KB.

Foresters describe the growth of shortleaf pine as slow but steady. For its first 2 years, shortleaf pine uses most of its resources developing a root system. During this period, faster growing competitors easily overtop it.

Shortleaf pine feeder roots are smaller and more abundant in. Hybrids between shortleaf pine (Pinus echinata Mill.) and loblolly pine (Pinus taeda L.) have increased since the s throughout the southeastern USA.

Previously, greater sprouting capacity and the formation of a basal crook that lowers the height of dormant buds may have favored pure shortleaf pine populations on fire prone sites. The objective of this study was to determine how Cited by: Shortleaf and loblolly pine trees (n = 93 andrespectively) from 22 seed sources of the Southwide Southern Pine Seed Source Study plantings or equivalent origin were evaluated for amplified.

The old growth forest was made up of Pinus echinata, known to foresters as shortleaf pine. Sawmill operators call them yellow pine. Sawmill operators call them yellow pine. The shortleaf pine is a big tree with an extensive native range in the southeastern states, ranging as far north as the Ohio River valley and as far west as the Great Plains.

IMMEDIATE FIRE EFFECT ON PLANT: Mature shortleaf pine is killed by high-severity crown fires, but withstands low- to moderate-severity surface fires [9,23].Shortleaf pine is most susceptible to fire in the first 6 to 10 years after establishment [].Seedlings up to 5 feet ( m) tall are usually top-killed, and saplings often suffer bark char, needle scorch, or needle consumption [].

For loblolly and slash pine, the volume equations over-predicted the average volume by and d/tree, respactlvaly, or about 5 to 10 percent of tree volume. The taper equation for loblolly was adequate, but the slash pine taper equation did not fit the data well.

There is no appropriate volume or taper model for shortleaf pine. Shortleaf pine has been successfully crossed with slash, loblolly, longleaf, and Sonderegger pines (P. elliottii, P. taeda, P. palustris, and P. × sondereggeri). Some of the hybrids have also been back-crossed.

Shortleaf pine × loblolly pine hybrids have also shown resistance to fusiform rust, have grown as well as or better than one or both. year traits in a pseudo-backcross {(slash x loblolly) x slash} and the open-pollinated families of the pure-species progenitors.

Hybridization between shortleaf pine and loblolly pine is causing loss of genetic integrity (the tendency of a population to maintain its genotypes over generations) in shortleaf pine, a species already exhibiting dramatic declines due to land-use changes.

Recent findings indicate hybridization has increased in shortleaf pine stands from 3% during the s to 45% for.

The two trees grow at about the same rate for the next 20 years. However, after about 45 years, the growth rate of the shortleaf pine outpaces the loblolly.
