Abstract Height-over-age curves and site-index prediction tables were derived using nonlinear polymorphic regression models with data from 25-year-old old-field plantations ranging from coastal North Carolina to southwestern Arkansas. Plots from heavy silty clay soils of the interior flatwoods of Mississippi exhibited height growth patterns noticeably different from the overall pattern. A separate table and set of curves were developed for such sites.

Abstract Callery pear (Pyrus calleryana Decne.) is rapidly spreading in the United States, gaining attention in the last two decades as a serious invasive pest. Recommended control methods include foliar, basal bark, cut stump, and hack-and-squirt application of herbicides, but there are few published studies with replicated data on efficacy. Four readily available herbicidal active ingredients and a combination of two active ingredients were tested for control efficacy against P. calleryana in old-field areas and loblolly pine (Pinus taeda L.) understory. Basal bark applications (triclopyr, triclopyr + aminopyralid), foliar applications (glyphosate, imazapyr), and a soil application (hexazinone) effectively killed P. calleryana with the exception of hexazinone at one site, where rainfall may not have been optimal. Foliar application of glyphosate provided the most consistent control. Our results demonstrate efficacy of registered herbicide formulations for P. calleryana control in two geographic locations and two habitat types. The need for development of integrated pest management programs for P. calleryana is discussed.

The beach plum, Prunus maritima Marsh is native to the sandy North Atlantic coast, from Newfoundland to North Carolina. It can grow well without irrigation, even on low-nutrient sandy soils, saline land, old-field and coastal beach where many other plants cannot survive. It is fine rootstock to improve stress tolerance of cion. The fruits of beach plum can be made into delicious jams, jellies and wine. This paper is aimed to introduce beach plum to people, and hope it can become an important multipurpose crop in Chinese coastal beach in the future.

As the role of distance learning within the educational setting expands, it is imperative that potential producers and receivers of these courses examine the prospects and problems of a distance learning initiative prior to embarking on this new educational journey. The authors provide guidance from their own distance learning experiences at the North Carolina School of Science and Mathematics. The article focuses on the importance of instructor and facilitator training, student selection, physical arrangements for the studio/classroom, and an evaluation plan.
