Latest Loblolly Pine Stories
More than 50 years of genetics work to increase loblolly pine production in the Southeast has improved the trees’ ability to act as carbon sinks that mitigate climate change.
Long-lived pine pollen makes it difficult to contain transgenic trees.
Pine trees grown for 12 years in air one-and-a-half times richer in carbon dioxide than today's levels produced twice as many seeds of at least as good a quality as those growing under normal conditions, a Duke University-led research team reported Monday (Aug. 3) at a national ecology conference.
Southern pines appear to grow and conserve water somewhat better in the carbon-dioxide-enriched atmosphere expected by mid-century, a Duke University study has found. However, any growth spurts appear to diminish over time, due at least in part to the kind of hot and dry weather that likely may become more common in the future. Thus, the researchers concluded, enhanced growth of pines may not constitute a long-term sink for human-produced carbon dioxide which might ameliorate global warming.
