چکیده
Rooted stem cuttings of forest trees are increasingly being used around the world to deploy elite genotypes in intensive forest plantations. In 1992, the NCSU Loblolly and Slash Pine Rooted Cutting Program was formed as an industrially sponsored research cooperative. The primary mission of the program is to conduct research to facilitate the operational use of rooted cuttings for the pines of the southeastern United States.

Study on Slash Pine (Pinus elliottii) as a Short Rotation Forestry in the North of Iran
Forests of Iran located on the Southern border of the Caspian Sea cover 1.9 million hectares. The Caspian forests are divided into four separate forestry areas. One of these being Guilan influx area with total area of 565000 hectares. About 30 to 40 percent of Guilan province forests are suitable to short rotation forestry for afforestation. Slash pine (Pinus elliottii) is one of the main exo...
متن کاملEffects of Nursery Characteristics on Field Survival and Growth of Loblolly Pine Rooted Cuttings
Morphological characteristics of rooted cuttings and seedlings of four open-pollinated loblolly pine families cultured at the G.H.W. Weyerhaeuser Nursery near Washington, North Carolina were assessed after lifting. Cuttings were visually assigned to nine grading classes and six putative cull classes. The nine grading classes represented a factorial of three root collar diameter classes (small [...
متن کاملLoblolly pine growth and soil nutrient stocks eight years after forest slash incorporation
Incorporation of forest slash during stand establishment is proposed as ameans of increasing soil carbon and nutrient stocks. If effective, the increased soil carbon and nutrient status may result in increased aboveground tree growth. Eight years after study installation, the impact of forest slash incorporation into the soil on soil carbon and nutrient stocks, foliar nutrients and loblolly pin...
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 کاملEffects of Plant Growth-Promoting Rhizobacteria on Loblolly and Slash Pine Seedlings
Loblolly and slash pine seed were inoculated at sowing with 1 of 12 different strains of plant growth-promoting rhizobacteria (PGPR) in the greenhouse. Time to germination and seedling densities were determined at 21 days, and seedling biomass was measured at 12 wk after sowing. All bacterial strains significantly increased the speed of seedling emergence over nontreated pine seed. By 12 wk, ho...
