“…Two recent shifts in focus have brought attention to the production of longleaf pine for restoration and reforestation. First, federal incentive programs have encouraged restoration of longleaf pine ecosystems (Hainds, 2002), and second, land managers are moving from pulpwood to sawtimber production because of higher economic returns (Kush et al, 2004). To meet this demand, use of container longleaf pine has increased dramatically because survival and growth often exceeds bareroot stock (Boyer, 1989;Barnett and McGilvary, 1997;South et al, 2005).…”

“…For one species with a grass stage, Pinus palustris (longleaf pine) of the southeastern United States, demand for container seedlings has increased dramatically during the past 15 years. Because survival and growth of container longleaf pine often exceeds that of bareroot stock (South et al 2005), historic concerns by land managers about poorer survival and slower initial growth of longleaf compared to other pine species have dissipated (Barnett 2002), resulting in renewed interest in planting longleaf pine in an attempt to realize the greater economic benefit of its sawtimber compared with other southern pine crops (Kush et al 2004). Federal incentive programs have further stimulated demand by encouraging restoration of longleaf pine ecosystems (Hainds 2002b); nearly 98 % of the original 36 million ha of longleaf pine forest type have been extirpated, imperiling many terrestrial species dependent on that habitat (Outcalt 2000;Jose et al 2006).…”

Few pine species develop a seedling grass stage; this growth phase, characterized by strong, carrot-like taproots and a stem-less nature, poses unique challenges during nursery production. Fertilization levels beyond optimum could result in excessive diameter growth that reduces seedling quality as measured by the root bound index (RBI). We grew longleaf pine (Pinus palustris), a grass stage species, in containers of four different volumes (60-336 ml) either coated with copper oxychloride or left untreated and fertilized at low, medium, or high levels of nitrogen (N). In general, N concentration of tissues rose as N rate increased, with larger changes in concentration occurring between low and medium levels than between medium and high levels. N rate influenced root tissue N concentration less than it did stems and needles. Subtle needle color differences caused by N rate were significant, suggesting its potential utility during nursery production. As expected, seedlings grew larger as container volume increased and as N rate increased. Copper treatment, which we posited could influence the RBI, tended to increase root-collar diameter and tap root biomass and decrease total root volume. Chlorophyll abundance was affected more by N rate than by container volume or copper treatment, but photosynthesis was affected more by copper treatment than N rate or container size. Although RBI was 25 % greater for seedlings grown in small containers with high N rates than those grown in large containers with low N rates, RBI ranged only from 11 to 15 %, well below the critical 27 % threshold.

“…These soil moisture gradients make them ideal for studying the effects of hydrology on leaf‐to‐stand scale productivity. Additionally, due to a variety of resistance and tolerance traits, these ecosystems have been proposed as resilient candidates for carbon storage and ecosystem services (Kush et al . 2004).…”

Environmental controls on carbon dynamics operate at a range of interacting scales from the leaf to landscape. The key questions of this study addressed the influence of water and nitrogen (N) availability on Pinus palustris (Mill.) physiology and primary productivity across leaf and canopy scales, linking the soil-plant-atmosphere (SPA) model to leaf and stand-scale flux and leaf trait/canopy data. We present previously unreported ecophysiological parameters (e.g. Vcmax and Jmax) for P. palustris and the first modelled estimates of its annual gross primary productivity (GPP) across xeric and mesic sites and under extreme drought. Annual mesic site P. palustris GPP was~23% greater than at the xeric site. However, at the leaf level, xeric trees had higher net photosynthetic rates, and water and light use efficiency. At the canopy scale, GPP was limited by light interception (canopy level), but co-limited by nitrogen and water at the leaf level. Contrary to expectations, the impacts of an intense growing season drought were greater at the mesic site. Modelling indicated a 10% greater decrease in mesic GPP compared with the xeric site. Xeric P. palustris trees exhibited drought-tolerant behaviour that contrasted with mesic trees' drought-avoidance behaviour.
