Use of Glyphosate and Imazapyr for Cogongrass (Imperata cylindrica) Management in Southern Pine Forests
targeted; thus, systemic herbicides offer one of the most effective tools in an integrated treatment approach. Cogongrass leaves grow directly from buds along rhizomes, without aboveground stems, and may reach 1.5 m in height (Holm et al. 1977, Bryson and Carter 1993). Because shoot meristems are below ground, cogongrass is tolerant of mowing and grazing. Cogongrass is fire tolerant, even thoug...
متن کاملEnergy exchange across a chronosequence of slash pine forests in Florida
We measured net atmospheric exchanges of energy and water vapor using eddy covariance along a chronosequence of Pinus elliottii plantations in north Florida: a recent clear-cut, a mid-rotation stand, and a 24-year-old, rotation-aged stand. Reflected energy averaged 0.26 of incoming solar radiation at the clear-cut and 0.18 at the closed-canopy stands. The sum of sensible (S), latent (LE) and so...
متن کاملMapping quantitative trait loci controlling early growth in a (longleaf pine x slash pine) x slash pine BC(1) family.
Random amplified polymorphic DNA (RAPD) markers were employed to map the genome and quantitative trait loci controlling the early growth of a pine hybrid F(1) tree ( Pinus palustris Mill. x P. elliottii Engl.) and a recurrent slash pine tree ( P. elliottii Engl.) in a (longleaf pine x slash pine) x slash pine BC(1) family consisting of 258 progeny. Of the 150 hybrid F(1) parent-specific RAPD ma...
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 کاملSlash Pine: Characteristics, History, Status, and Trends
-Slash pine is the premier tree species on many sites throughout the South. Its ease of establishment and early growth, however, has extended its range to many sites where its performance has been less than ideal. For that reason, the acreage and volume of slash pine are declining. Nonetheless, it will continue to be the favored species on many sites where it is the most appropriate and product...
