(Hamamelidales: Hamamelidaceae), is a species of interest for short-rotation plantation forestry in the southeastern United States. Despite its high levels of resistance to many native insects and pathogens, the species is susceptible to generalist defoliators during outbreak epidemics. The objective of this field study was to evaluate the potential impact of defoliation on sweetgum growth and productivity within the context of an operational plantation. Over three growing seasons, trees were subjected to artificial defoliation treatments of various intensity (control = 0% defoliation; low intensity = 33% defoliation; moderate intensity = 67% defoliation; high intensity = 99% defoliation) and frequency (not defoliated; defoliated once in April of the first growing season; defoliated twice, once in April of the first growing season and again in April of the second growing season). The responses of stem height, stem diameter, stem volume, crown volume, total biomass accumulation, and branch growth were measured in November of each growing season. At the end of the first growing season, when trees had received single defoliations, significant reductions in all growth traits followed the most severe (99%) defoliation treatment only. After the second and third growing seasons, when trees had received one or two defoliations of varying intensity, stem diameter and volume and total tree biomass were reduced significantly by 67 and 99% defoliation, while reductions in stem height and crown volume followed the 99% treatment only. All growth traits other than crown volume were reduced significantly by two defoliations but not one defoliation. Results indicate that sweetgum is highly resilient to single defoliations of low, moderate, and high intensity. However, during the three-year period of the study, repeated high-intensity defoliation caused significant reductions in growth and productivity that could have lasting impacts on yield throughout a harvest rotation.}, journal={Journal of Insect Science (Tucson, AZ)}, author={Jetton, R.

Fertilization increased constitutive resin flow, but only the younger trees sustained increased resin flow after wounding and inoculation treatments. An induced resin flow response occurred between 1 and 30 days after wounding and inoculation treatments. Wounding with inoculation resulted in greater resin flow than wounding alone, but increasing amounts of inoculum did not increase resin flow. Increased resin flow (relative to controls) lasted for at least 90 days after wounding and inoculation. This increase appeared to be limited to the area of treatment, at least in younger trees. The long-lasting effects of fungal inoculation on resin flow, as well as the response to fertilization, suggest that acquired resistance through induced resin flow aids in decreasing susceptibility of loblolly pine to southern pine beetle.}, number={6}, journal={TREE PHYSIOLOGY}, author={Knebel, Larissa and Robison, Daniel J. and Wentworth, Thomas R. and Klepzig, Kier D.}, year={2008}, month={Jun}, pages={847–853} }

Recent studies show that a variety of silvicultural activities affect the growth of yellow-poplar seedlings.

Weed control, fertilization and thinning treatments were imposed on rising 1- and 3-year-old naturally regenerated stands. Stem growth and monthly height growth patterns, and leaf physical and chemical parameters were compared by treatment during the third growing season after treatments were initiated. The response of yellow-poplar to fertilization suggests that inherent site resources are not suitable for optimal growth, especially when stem densities are high. Vector analysis of N, P and K responses to fertilization, weeding and thinning treatments demonstrated that yellow-poplar responded to ameliorations of N and P deficiencies. Thinned + weeded yellow-poplar, with or without fertilization, had a greater percentage of height growth later in the summer compared to other treatments. Foliar characteristics like leaf number, leaf size and nitrogen concentration were positively correlated with stem growth.

However, very few studies have explored silvicultural opportunities to manage these constraints. In this study, the effects of fertilization, density and vegetation control on rising 1- and 3-year-old upland mixed species NC Piedmont stands were monitored for 3 years following the imposition of treatments. Broadcast fertilization proved very beneficial in accelerating stem growth and promoting self-thinning at both sites. Weeding (non-arborescent vegetation) treatments without thinning had no effect on stem height. At both sites, substantial increases in tree size were noted for yellow-poplar and oaks when thinning and weeding treatments were combined. A significant fertilization effect on thinned plots was also noted for oaks.

Abiotic factors, such as nutrient supply and water relations, have the potential to modify this plant-insect-fungus interaction; however, little is known of the effects of inoculation with beetle-associated fungi on oleoresin flow. We observed that constitutive and induced resin yield in loblolly pine, Pinus taeda L., were affected by either fungal inoculation (with the southern pine beetle-associated fungus Ophiostoma minus (Hedgcock) H. & P. Sydow) or silvicultural treatment. The effects of mass wounding (400 wounds m(-2)) and mass wounding and inoculation with O. minus were assessed by comparison with untreated (control) trees. The treatments were applied to trees in a 2 x 2 factorial combination of fertilizer and irrigation treatments. Fertilization did not significantly affect constitutive resin yield. Even as long as 105 days post-treatment, however, mass-inoculated trees produced higher induced resin yields than control or wounded-only trees, indicating a localized induced response to fungal inoculation. We noted no systemic induction of host defenses against fungal colonization. Although beetles attacking previously attacked trees face a greater resinous response from their host than beetles attacking trees that had not been previously attacked, the effect of an earlier attack may not last more than one flight season. Despite mass inoculations, O. minus did not kill the host trees, suggesting that this fungus is not a virulent plant pathogen.}, number={6}, journal={TREE PHYSIOLOGY}, author={Klepzig, KD and Robison, DJ and Fowler, G and Minchin, PR and Hain, FP and Allen, HL}, year={2005}, month={Jun}, pages={681–688} }

However, damage from defoliating insects can significantly reduce the yield of SRWC and negatively impact their sustainability. Information regarding the relative resistance to defoliation of different SRWC clones is not only useful for deployment and breeding choices, but can also help elucidate ecological patterns of herbivore specialization. Laboratory feeding bioassays tested the resistance of 19 willow (Salix spp.) and six poplar (Populus spp.) biomass production clones to feeding by seven common folivorous insects. Defoliation was measured using a leaf area meter and results were standardized according to leaf area consumed per insect per day. Significant differences in resistance were found among clones (p ≤ .05). The most folivore-resistant groups included the six poplar clones and willow clones SH3, SP3, S546 and S625. Willow clones with S. eriocephala or S. dasyclados parentage were generally less resistant to herbivory than those with other parentages. Comparisons of univariate and multivariate approaches found that the multivariate techniques are robust and conservative, and provide an efficient means of screening a large number of clones in a development program. The multivariate approach provided a clearer sorting of folivores along a continuum of insect specialization. Such sorting may be useful in selecting model folivores to use in tree genetic improvement screening systems to efficiently reveal which clones are more likely to be resistant to multiple insect pests.}, number={2-3}, journal={FOREST ECOLOGY AND MANAGEMENT}, author={Nordman, EE and Robison, DJ and Abrahamson, LP and Volk, TA}, year={2005}, month={Oct}, pages={307–318} }

First, standard foliar nutrient ratios for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) were established using high-yield stands from a region-wide sweetgum fertilization study. DRIS indices were then calculated for the low-yield stands in the same study and stands from four other studies to evaluate foliar nutritional characteristics. Low-yield stands showed strong negative K imbalance, indicating insufficient K, but also showed strong positive Mg imbalance. Potassium imbalance was also observed in the other four data sets tested. DRIS analysis successfully identified the tendency for K insufficiency to increase from early to late in the growing season, probably due to K foliar leaching and low soil K supply. While insufficient N was common in all the stands tested, the DRIS analysis failed to identify any P imbalance. We recommend that K be applied in N:K ratios less than one to correct K imbalance problems in the studied sweetgum plantations. Supra-optimal Ca and Mg levels are expected to decline once insufficient N and K are corrected. DRIS analysis provides the means for diagnosing nutrient imbalance and a potential basis for prescribing corrective amendments in sweetgum plantations. #The submitted manuscript has been authored by a contractor of the U.S. Government.

In experiment one (established near Raleigh, North Carolina), 0, 56, 168, or 336 kg N/ha (ammonium nitrate) was applied in June 1998 to sycamore (Platanus occidentalis L.), sweetgum (Liquidambar styraciflua L.), green ash (Fraxinus pennsylvanica Marsh.), and swamp cottonwood (Populus heterophylla L.) to obtain foliar samples with a range of N concentrations. Significant regression equations were established between foliar N concentration (obtained through chemical analysis) and SPAD value for all four species studied in August 1998. In experiment two, the SPAD meter was further tested in 1999 on sweetgum in eastern NC to examine whether crown position and the date of measurement affect the relationship between SPAD meter readings and foliar N concentrations. The slopes of the regression lines were similar but the intercepts were variable among the dates and crown positions. The best correlations between the SPAD meter readings and foliar N concentrations were obtained for the upper crown position early in the growing season and for the lower crown position late in the growing season. The SPAD meter was demonstrated to be a useful tool for nondestructively assessing foliar N status, particularly for relative comparison purposes, and may have efficient application for field assessments in decision-making and operational nutrient management programs for hardwood species.

A pot experiment was conducted to test the hypotheses that (1) sweetgum (Liquidambar styraciflua L.) families have different patterns in biomass production and allocation, N uptake, and N use efficiency (NUE), because of their differences in growth strategies, and (2) sweetgum families that are more responsive to N additions will also have greater nutrient use efficiencies. Seedlings from two half-sib families (F10022 and F10023) that were known to have contrasting responses to fertility and other stress treatments were used for an experiment with two levels of N (0 vs. 100 kg N/ha equivalent) and two levels of P (0 vs. 50 kg P/ha equivalent) in a split-plot design. Sweetgum seedlings responded to N and P treatments rapidly, with increases in both size and biomass production, and those responses were greater with F10023 than with F10022. Growth response to N application was particularly strong. N and P application increased the proportional allocation of biomass to leaves. Under increased N supply, P application increased foliar N concentration and content, as well as total N uptake by the seedlings. However, NUE was decreased by N addition and was higher in F10023 than in F10022 when P was not limiting. A better understanding of genotype by fertility interactions is important in selecting genotypes for specific site conditions and for optimizing nutrient use in forestry production.}, number={electronic}, booktitle={Optimizing nitrogen management in food and energy production and environmental protection: Proceedings of the 2nd International Nitrogen Conference on Science and Policy.

This will lead to increased production and a strengthening of the commercial prospects of these plantations. The primary objective of this study was to use a multivariate approach to evaluate the relative clonal performance of 38 willow and hybrid poplar clones, deployed in a genetic selection trial based on a coppice rotation system established in central New York State (NY) in 1997. Cluster analysis was conducted using survival, several individual plant growth attributes, and insect defoliation, all measured during or at the end of 1998. Two linear functions developed using discriminant analysis, comprising primarily of attributes related to tree vigor and site adaptability; tree volume index and length of growing period, explained most of the variation (98.5%) among the clusters. Eight of the 38 clones evaluated are expected to be high biomass producers, and are recommended for more extensive clone-site trials and commercial scale plantations across central NY and the northeastern United States (US). The results of this study indicate a possible approach to more effective juvenile selection in tree improvement programs, and insights for a refinement of the current SRIC tree ideotype.}, number={4}, journal={BIOMASS & BIOENERGY}, author={Tharakan, PJ and Robison, DJ and Abrahamson, LP and Nowak, CA}, year={2001}, pages={237–247} }

Clones were grouped into growth potential classes using cluster analysis and indices of total growth and canker severity. Statistical significance of growth potential classes was tested using discriminant analysis. Seven of the 54 clones examined (DN16, NM6, NE17, D51, DN38, DN55 and NE21) were recommended for additional evaluations in larger scale clone-site trials. The technique presented in this report facilitates hardwood clone performance evaluation for a wide variety of desired products.}, number={2}, journal={BIOMASS}, author={ABRAHAMSON, LP and WHITE, EH and NOWAK, CA and BRIGGS, RD and ROBISON, DJ}, year={1990}, pages={101–114} }

In the course of this work significant information on the scale's biology was also obtained. M. josephi developed and produced viable eggs on different provenances of Aleppo pines ( Pinus halepensis ), brutia pines ( P. brutia ssp. brutia ), and eldar pines ( Pinus brutia ssp. eldarica ). Three-year-old Aleppo pines and eldar pines were considered the best media for routine production of M. josephi. More than 600 male pupae and adult females from 10 to 12 ovisacs were produced per sapling. Third-instar males tended to pupate near the plastic bags in which saplings were planted and were collected directly from the polythene sheet. Routine collection of adult females was best accomplished by striking the sapling over a white sheet of paper. Repeated two or three times, this procedure was adequate in removing 95% of the females. Careful and parallel collection of male pupae at intervals of 1–4 d eliminated adult males from the system and provided us with a pure culture of virgin females. In greenhouses, the earliest emergence of third-instar males and adult females started 18 and 34 d after infestation in early summer, and 34 and 45 d during winter, respectively. The effect of constant temperature, between 10 and 30;°C, on rate of development of feeding and nonfeeding stages of M. josephi was determined. The low temperature threshold of feeding larvae (2.4°C) allows continuous development during winter in Israel, whereas higher low temperature thresholds of nonfeeding life stages (8°C) probably delay emergence of adult males and egg hatching until temperatures are suitable for males to locate the females and crawlers to disperse. The minimal effect of increasing temperature above 20°C on developmental rates coincides with the effect of the temperatures on the scale's principal host, P. halepensis. A young male could fertilize an average of six females between 1 and 4 h old, whereas older males were less successful. Young males mated with a small number of females among the older age groups.}, number={3}, journal={ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA}, author={MENDEL, Z and SAPHIR, N and ROBISON, D}, year={1990}, month={May}, pages={532–537} }
